Full textAbstract:
A programming to make parts are CNC Programming (Computer Numerical Control Programming) for machines. An NC program consists of a sequence of instructions that control the motion and automatic sequences of an NC Machine to perform a particular processing task. In a general sense, the term NC programming refers to the creation of control data for machining workpieces on NC and CNC machines. NC programming has a decisive influence on the cost-effectiveness and profitability of NC manufacturing. The selection of a programming system is mostly guided by the need for software that is suitable for the application at hand, readily available, and as universally applicable as possible.

Full textAbstract:
The motion relationship model of all axes involved in CNC hobbing machines is established. A single pitch adjustment method based on motion coupling relationship in gear hobbing is proposed. With position adjustment of only 0 to 1 pitch, the same motion coupling relationship during the whole machining process can be guaranteed. Though automatic programming system based on SINUMERIK 840D, the coupled motion control and adjustment in CNC hobbing process is realized. And practical application in CNC hobbing machines shows that this method can reduced adjustment time effectively during process, improving processing efficiency.

Abstract. The article presents methodology for designing optimal feed control cycles resistant to unstable machining conditions for a batch of parts in round grinding operations performed on CNC machines. To improve the quality and reliability of control programs for CNC machines, a digital twin (DT) is proposed to be used. It performs virtual testing of a given grinding cycle for the possibility of defect occurrence at some combination of variable technological factors. To design the optimal grinding cycle by calculating the optimum trajectory of the radial feed change cycle, we propose the dynamic programming method (DPM) used in solving the classical transport problem, in which a network of roads with intermediate stations is specified. In the task it is necessary to find the optimal trajectory of transport. The conditions for the appearance of defects detected by the DT are introduced into the system of restrictions, and the feed cycle is again optimized in the DPM optimization system. A new optimized cycle is again tested by the DT. These iterations are repeated until the DT fixes the present of a defect for the operation. The methodology proposed in the article for the synthesis of digital twin and DPM technologies at the stage of preparation of control programs for CNC machines makes it possible to guarantee the maximum productivity of the grinding operation while ensuring the specified quality of the machined surface under varying processing conditions that vary within the specified limits.

The priority task of the development of mechanical engineering is complex mechanization and automation of technological processes of mechanical processing. This problem can be solved by the introduction of machine tools and machine complexes with numerical control. CNC equipment combines the flexibility of universal and high performance of special automatic equipment, which significantly changes the nature of production and makes it mobile, meeting the requirements for continuous improvement and updating of mechanical engineering products. However, such equipment is quite complex, and its acquisition is associated with large financial costs, therefore, the problem of efficient use of CNC machines is a priority for most mechanical engineering enterprises and is inextricably linked with the need to create various programs. The article presents a theoretical analysis of the VGA interface, as well as a practical implementation of this interface, written in the Verilog programming language, on the Terasic DE10-Lite debugging board, with the MAX10 10M50DAF484C7G programmable logic integrated circuit and other peripheral modules. The practical significance of the work is familiarizing with programmable logic integrated circuits of the Intel FPGA family, obtaining basic knowledge in working with the Quartus Lite computer-aided design system (CAD), and learning the basics of programming programmable logic integrated circuits in the Verilog language. In the course of the work, the algorithm for writing code in the Verilog programming language for implementing the VGA interface on the DE10-Lite debugging board was described in detail. The software and mathematical excerpts used in the work are publicly available on the Internet, which allows anyone to carry out similar work and make sure that the written codes and the obtained conclusions are correct. This work can be used not only for writing programs for machine tools, but also for teaching students in the field of developing electronic devices in terms of their algorithmization and for organizing laboratory work, as well as for creating and designing real devices both in production and within a higher educational institution, for example, for developing laboratory work using specialized CAD. Familiarization and study of this programming language are conducted within the walls of one of the leading engineering universities of the Russian Federation, the Bauman Moscow State Technical University.

A promising direction in the production of high-pressure pipelines is the use of composite materials with special properties. Characteristics of composite products are set by reinforcement schemes and the use of various binders. The stability of the strength characteristics significantly depends on the stability of the process of laying reinforcing fibers. The development of automated technological systems of production, ensuring the stability of the process, is an urgent task. A method of fiberglass pipe bends manufacturing by the method of pre-impregnated tape winding on a folding mandrel. To implement this method the problem of developing technological equipment, equipment and methods of adjustment are solved. The proposed solution provides the formation of a branch from the inner surface. The kinematic scheme of the equipment realizes the rotation of the tape stacker around the axis of the cross-section of the mandrel and the longitudinal-angular displacement of the mandrel relative to the stacker, which provides the possibility of cylindrical and spiral stacking of the tape. The installation of tap winding, which is a three-axis CNC machine that implements the proposed scheme, is described. The rotation of the coils with tape around the mandrel is provided with a hollow rotary axis – stacker. Moving the mandrel relative to the stacker is provided by its installation on a movable platform. Following the proposed method of manufacturing bends, the outer surface of the collapsible mandrel ensures the formation of the inner surface of the branch, including the connecting-butt surfaces. Rules for the choice of the surface of the connector mandrel, ensuring its extraction from the manufactured branch is formulated. A method for programming winding operations has been developed. A method for determining the parameters of the control system of the CNC system is given, which specifies the structure of laying the tape and the wall thickness of the outlet. A procedure is described for setting up a tap manufacturing operation consisting in changing the relative position of the installation elements and the mandrel fixing devices. The use of traditional for CNC systems approaches to adjust the coordinate systems ensures the accuracy of the initial position is not worse than 0.1 mm.

To date a wide variety of computer aided tools are available for computer numerical controlled (CNC) automated machine-tools. Solid modelling software and 3D computer-aided design (CAD) are know firmly established in the early design stage whereas computer aided machining (CAM) and computer numerical control (CNC) simulator software is employed during the manufacturing stage. Training in the use of these systems is often undertaken in separate technical disciplines and training courses (e.g., graphic representation, mechanical design, computer numerical control programming, computer-aided machining, manufacturing technology, etc.), but students often lack a sound global understanding of these tools and fail to comprehend the full potential of integrating these applications. Thus, the aim is to propose a global methodology for the teaching of computer aided automated machining systems by integrating an array of computer aided tools (3D solid modelling, CAD/CAM software, CNC simulators, DNC communication, etc.) in order to enhance knowledge and develop skills of the entire manufacturing process i.e., to provide practical hands-on tasks from the early design stages to the final stages of the computer aided automated machining of a product.

Canned cycles are predefined machine instructions stored permanently in the machine controller. These are used while writing part program to perform machining operations that are of repetitive nature. Whenever G & M code for these canned cycles appeared in part program, the controller of the machine calls already stored instructions and executes. However all CNC machines may not have facility to run part programs with canned cycles due to lack of computational facilities. The developed utility in this program allows part programmers to write part program using canned cycles and later on convert them in simplified programs to run on the low cost CNC machines. Present work deals with computations required to convert a canned cycle into linear interpolation based on the machining parameters assigned in that canned cycles. Developed code reads the CNC part program and extracts the desired points from presented canned cycles and perform desired geometric computations to converts it into simple part programs with elimination of canned cycles and writes in another text file in the form of a part program. Developed system is user friendly and made available online for users at http://virtualcnc.iiitdmj.ac.in. It implies a web based online client-server architecture which facilitates user to send their own CNC part programs with canned cycles at server site via internet and get the simplified part program which contains only linear interpolation at their end. Therefore the developed utility in this work can also provide an interface/exchange program for part programs between various CNC machines of different make.

Generation of the part programs, or tool paths, for products to be manufactured by computer numerical control (CNC) machines is very important. Many methods have been used to produce part programs, ranging from manual calculations to computer aided design/ manufacturing (CAD/CAM) systems. This work introduces a new technique for generating the part programs of existing products using the latest technology of computer vision. The proposed vision system is applicable for two-dimensional vertical milling CNC machines and is calibrated to produce both metric and imperial dimensions. Two steps are used to generate the part program. In the first step, the vision system is used to capture an image for the product to be manufactured. In the second step, the image is processed and analysed by software specially written for this purpose. The software CNCVision is fully written (in lab) using Microsoft Visual C++ 6.0. It is ready to run on any Windows environment. The CNCVision software processes the captured images and applies computer vision techniques to extract the product dimensions, then generates a suitable part program. All required information for the part program is calculated automatically, such as G-codes, X and Y coordinates of start-points and end-points, radii of arcs and circles and direction of arcs (clockwise or counterclockwise). The generated part program can be displayed on screen, saved to a file or sent to MS Word or MS Excel. In addition, the engineering drawing of the product can be displayed on screen or sent to AutoCAD as a drawing file.

Automated tool changing of CNC machines reduces the cycle time of operations as most processes require a number of different tools to complete a task. The machine can be pre-loaded with the required tools and programmed to automatically retrieve the tools as required. CNC machines will often run unattended or work too quickly for manual intervention, so it is important that safety features and checks are built in to prevent damage. The purpose of this research project was to modify a tool changing system for a reconfigurable machine tool (RMT), which was previously developed in the Department of Mechatronics. The RMT is capable of performing milling, drilling and electric discharge machining (EDM). In this research, the automated tool changer (ATC) was developed and successfully integrated into the RMT, and interfaced with the machine controller. The redesigned ATC is able to provide fast, reliable and safe tool changing for a variety of tools.

The use of computer technology in manufacturing industries can improve manufacturing flexibility significantly, especially in manufacturing processes; many software applications have been utilized to improve machining performance. However, none of them has discussed the abilities to perform direct machining. In this paper, an integrated system for remote operation and monitoring of Computer Numerical Control (CNC) machines is put into consideration. The integrated system includes computerization, network technology, and improved holding mechanism. The work proposed by this research is mainly on the software development for such integrated system. It uses Java three-dimensional (3D) programming and Virtual Reality Modeling Language (VRML) at the client side for visualization of machining environment. This research is aimed at developing a control system to remotely operate and monitor a self-reconfiguration fixture mechanism of a CNC milling machine through internet connection and integration of Personal Computer (PC)-based CNC controller, a server side, a client side and CNC milling. The performance of the developed system was evaluated by testing with one type of common protocols particularly User Datagram Protocol (UDP). Using UDP, the developed system requires 3.9 seconds to complete the close clamping, less than 1 second to release the clamping and it can deliver 463 KiloByte.

The diameter of the workpiece is measured, while the workpiece is located on the CNC (computer numerical controlled) turning machine, using a new laser instrument and technique. The optical instrument is based on the laser Doppler principle, using an He—Ne laser as a light source. It obtains data by detecting the scattered light from the surface of a rotating workpiece, processing this data with respect to the rotation of the spindle and providing a value representing the workpiece diameter. The basic resolution of the system depends on the wavelength of the laser and geometry of the optics. Higher resolution can be achieved by obtaining the data from the workpiece surface over more than one complete revolution of the spindle. The resolution for one revolution of the spindle is 0.5μm and for ten 0.05μm. The measurement system is also integrated with the CNC turning machine, particularly for autofocusing of the instrument. The instrument is mounted on the tool holder of the CNC turning machine, which is focused by means of a tool offset parameter for non-contact measurement of each different diameter. Autofocusing is carried out using the MI5 machine tool interface unit which is already established for the Renishaw probe system, according to CNC part programming. The performance of the proposed technique and instrument is verified through the experiments.

Abstract For precise job manufacturing, system should possess good dimensional accuracy and surface finish. In applications like drilling, punching, marking, boring, tapping work piece is positioned firstly and then cutting tool performs its action while motion axes are kept stationary. In traditional approach for such applications, manufacturer uses highly expensive CNC machine for programming job cycle and executing the same. Big scale manufacturer can afford such highly expensive machines but for small scale mechanical job manufacturing industry we have to think of low-cost solution that can deliver high class output. In this project we are trying to propose low-cost design which gives similar functionality as that of high-cost CNC machine. By applying this machine in industry, it can acquire the multi generation brief time. In order to perform some operation which requires continuous cutting over a pre-defined curve, CNC machines are used as the traditional machines in the industry. Installation of a CNC machine requires a high financial investment and a skilled labour to perform the different operations on the machine. Apart from that the maintenance cost of such machine are also high. In small scale industries where the operations are performed on small job pieces, the installation of such high-cost CNC machine is very difficult; hence this project work is taken up in which a low-cost CNC laser cutting machine is designed using the Arduino. This CNC laser cutting machine will be quite useful for small scale industries where the job size is not very large. Also, the machine does not require a highly skilled labour to perform operations.

This paper reports a new technology for designing control programs for contour milling on CNC machines. The technology enables stabilization of the cutting process along the entire contour at the optimal level by controlling the feed, which ensures an increase in productivity when meeting the requirements for restrictions. Moreover, the effectiveness of using the technology improves with an increase in the complexity of the contour by changing the curvature of the surface. A mathematical model has been built for the interaction between the cutter and workpiece in the cutting zone when machining contours with variable curvature, which makes it possible to determine the main characteristic of the cutting process – the rate of cutting the allowance. The technology involves the use of a control program in G codes designed in any CAM system. At the first stage, a shape-formation trajectory in the form of a two-dimensional digital array is derived from the program. At the second stage, the cutter workpiece engagement in the cutting area is modeled simulated while determining the main characteristic of the cutting process – an analog of the material removal rate. And at the final stage, the simulation results are used to design a new control program, also in G-codes, with a new recorded law to control the feed, which enables the stabilization of the cutting process along the entire milling path. The software for the new technology has been developed, which automatically converts the preset control program in G-codes into a two-dimensional digital array, simulates the milling process, and designs a new control program in G-codes based on its results. The results of the experimental study into the milling of the preset contour using the developed simulation program showed an increase in productivity by 1.7 times compared to the original control program, designed in a conventional CAM system

Verification of programming of various control systems and production of mathematically defined shaped surfaces on 3D CNC milling machine is a challenging technological process. Appropriate design and optimization of tool path is essential for the production of high-quality surfaces with the required accuracy and roughness. This paper presents the design of shaped surfaces in various programming means in order to evaluate both the accuracy of the shape manufactured by the production machine and also by program created shapes for control systems of 3D milling machines. Based on the analysis of mathematically defined shaped surfaces to evaluate both accuracy of shape of 3D milling machine and also applied programs for the programming of the selected control system the shaped surface "Interface" was chosen. The advantage of mathematically described surface is a better way to evaluate the accuracy compare to surface modeled e.g. by Bezier ́s curves. Mathematically described surfaces enable us to optimize their shapes by available mathematical functions. Typical example the derivatives are, which make it possible to search extremes. Verification of the shaped surfaces accuracy according to created control programs was solved using the 3D Carl-Zeiss coordinate system and also HOLOS software. Verified programs for the NC machine programming were in CATIA V5, Pro/Engineer and EqCAM. The result is an optimally designed original EqCAM program for 3D CNC milling machine programming, which generates optimal NC codes and bypasses various built-in interpolations, and by precise control at every step it is possible to achieve maximum accuracy and quality of machined surface for each 3D CNC milling machine.

Industrial programming is a tiresome and time-consuming task that requires technical skill. Thus, new and more intuitive ways for people to interact with CNC machines are required to make programming easier. The goal is to present two methods of programming that helps users to program a machine in an intuitive way, providing a high-level of abstraction from the machine language. Therefore, this paper presents a CAD-based system to program from a 3D CAD environment, allowing users with essential CAD skills to generate programs off-line in order to facilitate and accelerate these related tasks. This is feasible due to a relatively low cost and commercially available CAD packages that enable the user to generate machining programs. The method used to get data from CAD and techniques to manipulate, simulate and convert it into CNC machine commands are presented herein. Finally, the effectiveness of the two methods is showed when the time and wastes saved in 3D programming is compared to 2D programming to perform the same task. This presented method can also contribute to improve the quality of work, increase productivity, standardize work routines, and strive for excellence in adding value. A case study is showed to evidence the benefits reached.

In this article, a new method for rapid tool movement in CNC machines is presented. Firstly, a single digital camera, installed on the Z-axis, captures the image of the workpiece on the work table. Image processing techniques, implemented using MATLAB, are then used to convert the image into a binary black and white image. This allows the locations of protruding edge sections on the workpiece, which could impede tool movement, to be identified. Quadtree decomposition is then performed on the binary image, and possible paths from the tool current location to its target location are found. These paths are then analysed based on the tool diameter clearance and the distance to the goal, and the shortest path with sufficient tool clearance is selected. A Visual Basic program then converts the selected path into G-code commands that provides instructions to the CNC machine tool such that this path is followed. With this method, the workpiece fixture location would not have to be precise as the imaging system would be able to automatically identify the target location with respect to the tool current location, along with the optimal path to reach it.

The capability of any manufacturing system primarily depends on its available machine tools. Thus machine tool representation is a vital part of modelling any manufacturing system. With the rapid advances in computerized numerically controlled (CNC) machines, machine tool representation has become a more challenging task than ever before. Today's CNC machine tools are more than just automated manufacturing machines, as they can be considered multi-purpose, multi-tasking, and hybrid machining centres. This paper presents a versatile methodology for representing such state-of-the-art CNC machining system resources. A machine tool model is a conceptual representation of the real machine tool and provides a logical framework for representing its functionality in the manufacturing system. There are several commercial modelling tools available in the market for modelling machine tools. However, there is no common methodology among them to represent the wide diversity of machine tool configurations. These modelling tools are either machine vendor specific or limited in their scope to represent machine tool capability. In addition, the current information models of STEP-NC, namely ISO 14649, can only describe machining operations, technologies, cutting tools, and product geometries. However, they do not support the representation of machine tools. The proposed unified manufacturing resource model (UMRM) has a data model which can fill this gap by providing machine specific data in the form of an EXPRESS schema and act as a complementary part to the STEP-NC standard to represent various machine tools in a standardized form. UMRM is flexible enough to represent any type of CNC machining centre. This machine tool representation can be utilized to represent machine tool functionality and consequential process capabilities for allocating resources for process planning and machining.

CNC equipment is flexible, versatile, and has high performance. The use of such equipment significantly changes the nature of production and makes it mobile, meeting the requirements for continuous improvement and updating of mechanical engineering products. However, CNC machines are quite complex, and their acquisition is associated with large financial costs, therefore, the problem of efficient use of CNC machines is a priority for most mechanical engineering enterprises and is inextricably linked with the need to write various programs. Variants of the implementation of sequential, parallel correction and feedback correction methods in the Simulink package from MATLAB CAD are proposed. When performing the work, customizable library blocks are used, which are available for students to access on the official website of the software manufacturer. Schemes for each correction method with a description of the included blocks are presented. The output of the results and the comparison of the obtained data is carried out using a software oscilloscope built into the package, which allows clearly understanding the difference between the schemes. A comparison is made on the example of various types of signals for the most objective assessment of the quality of signal correction by one method or another. The practical significance of the work is familiarization with the MATLAB CAD Simulink package and consideration of possible ways to implement these correction schemes, as well as availability of the same schemes for self-construction in this CAD. This work can be used not only for teaching students of higher educational institutions in the field of development, debugging and coding of electronic and radio-electronic devices in terms of describing the algorithm of their work, but also for organizing laboratory work on courses of disciplines related to this topic, as well as when creating and designing real devices in production. Familiarization and study of this programming language are conducted within the walls of one of the leading engineering universities of the Russian Federation, the Bauman Moscow State Technical University.

Finally the proposed approach is implemented in a prototype system and tested with an example STEP-NC program for turning, which shows not only the feasibility of the proposed approach for information extraction and process evaluation, but also the possibility of using simple transitional systems to bridge the gap between the sophisticated STEP-NC part program and conventional CNC machines.

Digital Twin-based Cyber-Physical Quality System (DT-CPQS) concept involves automated quality checking, simulation, and prediction of manufacturing operations to improve production efficiency and flexibility as part of Industrie4.0 initiatives. DT-CPQS will provide the basis for the manufacturing process to march towards an autonomous quality platform for zero defect manufacturing in the future. Analysing sensor data from the CNC machine and vision monitoring system it was concluded that there was enough signal data to detect quality issues in a part being machined in advance using statistical/mathematical models (Smart PLS) and using machine learning algorithms. This allows the operator to take corrective actions before the resultant part ends in a quality failure and reduces the inspection time. The proposed approach forms the basis in expanding this concept to a large machine shop wherein by monitoring various parameters of the machines and state variables of the tools we can detect quality issues and develop an automated quality system using machine learning techniques.

Introduction. One of the main reasons that modern multi-purpose CNC machines do not use the capabilities of multi-tool processing is the lack of recommendations for design in this direction and, accordingly, for adjustment schemes. The study of the possibilities of multi-tool processing on multi-purpose machines is the subject of the work. The purpose of research: The problem of developing full-factor matrix models of dimensional accuracy and its sensitivity to the machining process is considered to increase the machining efficiency while ensuring machining accuracy using the technological capabilities of multi-tool machining on modern multi-purpose CNC machines. For this purpose, full-factor matrix models of the size scattering fields performed on multi-tool double-carriage adjustments have been developed, taking into account the cases of processing parts with dimensions that differ sharply in different directions, which are often encountered in practice, and in this case, the significant influence of the turns of the workpiece on the processing error, especially in directions with sharply different overall dimensions. Results of research: The developed accuracy models make it possible to calculate not only plane-parallel displacements of the technological system for double-carriage adjustments, but also angular displacements around base points, take into account the combined effect of many factors – a complex characteristic of the subsystems of the technological system (plane-parallel matrix of compliance and angular matrix of compliance), the geometry of the cutting tool , the amount of bluntness of the tool, cutting conditions, etc. As a result, based on the developed accuracy models, it is possible to obtain several ways to control multi-tool machining, including improving the structure of multi-tool adjustments, calculating the limiting values of cutting conditions. Based on the developed full-factor matrix models, it became possible to develop recommendations for the design of adjustments and the creation of an automated design system for multi-tool machining for a group of modern multi-purpose CNC lathes. Scope of the results: The results obtained can be used to create mathematical support for the design of operations in CAD-systems provided for multi-tool multi-carriage machining performed on multi-purpose machines. Conclusions: The developed models and methodology for simulating the machining accuracy make it possible to increase the accuracy and efficiency of simultaneous machining, to predict the machining accuracy within the specified conditions.

This study aims to build a machine scheduling method that involves the cutting tool management in parallel-type flexible manufacturing systems. These systems consist of multi-axis CNC machine tools and are equipped with an automated tool changer and a large-capacity tool magazine. The target scheduling problem could be described as a multi-objective parallel scheduling problem. We consider the availability of cutting tools stored in the magazine as so-called “machine eligibility,” and propose a two-phase scheduling method for tool allocation and job sequencing on machines to minimize the workload balance between machines and the total completion time. Two mathematical models for tool allocation are provided: a machine-eligibility-based model and an enhanced version of the model that considers each cutting tool. A series of computational experiments demonstrates the effectiveness of the proposed method. We also clarify the relationship between schedule performance measures and job routing flexibility in the system.
