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.

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.

This study proposes a method for the online tool condition monitoring of the tools used for the cutting processes in computer numerically controlled (CNC) turning machines. Through this study, we have developed a device for online tool condition monitoring based on the machine vision/image capture method. One of the key features of the image capture device developed through this study is that it will not be affected by contamination from the cutting environment. Wear and tear of machine tools can typically be classified into four categories: fracture, built-up edge, chipping, and severe wear of the insert tip condition of the external turning tools. Methods for inspection of wear and tear used in the past relied on manual inspection of the tool insert or on statistical data analysis of cutting history. However, these methods were unable to effectively enhance the production efficiency of automated turning manufacturing. By leveraging the rapid advances in software, hardware devices, and technology for enabling machine vision in recent years, we have developed an automated online inspection system for tool condition monitoring, which can provide information regarding wear and tear in real time without the need for manual intervention, thereby improving production efficiency. To overcome the impact of contamination in the cutting environment on the image capture device and the tool images it records and to improve the robustness of the tool condition inspection method, we performed detailed analyses using four different images. The images captured include the tool wear exposure image, the tool flank exposure image, the tool wear feature image, and the tool flank feature image. For the tool wear features that cannot be inspected easily, we designed a light source device with an inbuilt capability for auto-modulation of light intensity. This helped maintain a similarity in luminance across different tool images captured, thereby enabling the selection of the appropriate wear feature image for analysis. An automated inspection of the condition of tools was conducted online using batch test samples provided by the manufacturer of the mechanical parts to verify the feasibility of applying the machine vision system developed in this study for actual monitoring of tools in the CNC turning machines. With the rapid growth in practical applications of robotized manufacturing cells (RMCs), this study also used the same method for the inspection of the RMCs by mounting the automated tool condition inspection module on the manipulator with six degrees of freedom, and by carrying out repeated inspections of the CNC turning tools for the manufacturing cell. Thus, we verified the stability and repeatability of the automated inspection system for the RMC and validated the robustness of the offset tool image captured using the machine vision device.

AbstractRobotic drilling systems have been used in the manufacture of large aerospace components for a number of years. Systems have been developed by several systems integrators in order to accurately drill materials from CFRP to Titanium. These systems, however, have been unable to achieve large diameter holes in Titanium due to reduced structural stiffness and end effector capabilities. Typically, large holes are either drilled using large cartesian CNC-controlled machines or drilled using automated drilling units (ADU). However, there is a pull from aerospace OEMS to move away from large monolithic machines, in favour of flexible robotic system. Flexible robotic systems provide a number of benefits for large structure assembly. The following report primarily outlines drilling trials conducted on the Accurate Robotic Machining System, during which holes from 25 mm to 32 mm ID were drilled in titanium implementing an empirical test schedule. Additionally, a discussion on the benefits of drilling large diameter holes using flexible robotic platforms.

A CNC machine can be programmed in different ways to machine a workpiece. In addition to creating the cutting program, many other factors also need to be considered or programmed. These include workholding devices, cutting tools, machining conditions as well as the machining strategy. The first generation CNCs were programmed manually and punched tapes were used as a medium for transferring the machine control data (MCD), that is, G-codes into a controller. Tapes were later replaced by RS232 cables, floppy disks, and finally standard computer network cables. Today’s CNC machines are controlled directly from files created by CAD/CAM or CAM software packages, so that a part or assembly can go directly from design to manufacturing without the need of producing a drafted paper drawing of the component. This means that for the first time, bringing design and manufacturing under the same automation regime becomes a reachable target. Error detection features give CNC machines the ability to alert the operator in different ways including giving a ring to the operation’s mobile phone if it detects that a tool has broken. While the machine is awaiting replacement on the tool, it would run other parts that are already loaded up to that tool and wait for the operator. The focus of this chapter is on a detailed account of the basics of CNC programming, and the emphasis is on G-code and Automatic Programming Tool (APT). G-code is still the dominant manual programming language for CNC machine tools. It is also the main form of control commands many CAD/CAM (or CAM) systems output. APT was developed soon after G-codes and CNC machine tools were developed to alleviate the drudgery work of straight G-code programming. Modern CAD/CAM systems these days are now becoming the main-stream tools for CNC programming.

Full textAbstract:
Wire Electric Discharge Machining (WEDM) stands out as a non-contact and nearly force-free machining technique able to cut complex workpieces, delivering dimensional accuracy and superior surface finishing, especially for exotic super-hard materials. On the other hand, machining with six-axis industrial robots (IR) has received much attention due to its notorious advantages over CNC machines to deliver cost efficiency, large envelope, and complex tool kinematics. However, robot machining suffers from severe limitations regarding the tool payload, chatter, repeatability, accuracy error, complex programming and frequently poor surface finishing. This paper investigates the benefits of combining a robot with WEDM to exploit the advantages of both techniques. However, the new system design is not trivial and will involve a transdisciplinary approach and inventive problem solving to design and control a WEDM end-effector. The present study adopts the TRIZ algorithm approach to design a novel WEDM end-effector and define actions to be taken to achieve a flexible and accurate robotic machining system for hard-to-cut materials.

Web-based learning is rapidly becoming the preferred way to quickly, efficiently, and economically create and deliver training or educational content through various communication media. This chapter presents systems that use speech technology to emulate the one-on-one interaction a student can get from a virtual instructor. A Web-based learning tool, the Learn IN Context (LINC+) system, designed and used in a real mixed-mode learning context for a computer (C++ language) programming course taught at the Université de Moncton (Canada) is described here. It integrates an Internet Voice Searching and Navigating (IVSN) system that helps learners to search and navigate both the web and their desktop environment through voice commands and dictation. LINC+ also incorporates an Automatic User Profile Building and Training (AUPB&T) module that allows users to increase speech recognition performance without having to go through the long and fastidious manual training process. New Automated Service Agents based on the Artificial Intelligence Markup Language (AIML) are used to provide naturalness to the dialogs between users and machines. The portability of the e-learning system across a mobile platform is also investigated. The findings show that when the learning material is delivered in the form of a collaborative and voice-enabled presentation, the majority of learners seem to be satisfied with this new media, and confirm that it does not negatively affect their cognitive load.

A reconfigurable gear machining numerical control system (NC/CNC) architecture is proposed in this paper. The CNC platform can be quickly applied to gear hobbing, shaping, milling and grinding machine, through simple reconfiguring or parameter setting. Parametric automatic programming technology, high speed and high precision electronic gearbox, process database technology are studied. Based on the analysis of the gear machining process, the mathematic model on automatic programming of gear machining is established. Based on the Windows CE operating system, the CNC gear machining automatic programming system is developed on the ARM+DSP hardware platform, including the design of human-machine interface, automatic programming algorithm and other modules. With the support of the automatic programming and process database modules, NC codes can be generated automatically just by inputting gear parameters, tool parameters and process parameters, then, the interpolation data structure can be generated by interpreter module. A new kind of software electronic gearbox (EGB) and its implementation methods are also researched in the embedded CNC. Data flow among the modules is analyzed. Finally, experiments are conducted, and the tracking error and contour error are analyzed. The results show that the proposed gear machining CNC architecture is effective.

Abstract Common industrial applications of body-guiding linkages occur with robot (or CNC machine) interaction at workstations in automated production and assembly lines in industry. A linkage in such cases is generally operated horizontally where large deflections at the body location occur creating positioning and orientation errors of the body. These errors must be delivered to the interacting robot to program its motions and operating geometries to eliminate effects of errors on the performed tasks at the workstations. Driving the linkage at high speed, generating dwells at workstations, experiencing efficient dynamic behaviors is an important phase of its design. In this article, a four-bar linkage guides the body. A disk cam with translating roller follower drives a slider-crank loop driving the body guiding linkage providing dynamically efficient motion of the guided-body along its path and the mechanism. Processes of programming motion of the rigid-body along its path, obtaining the corresponding motions of the links of the mechanism, designing the cam-follower mechanism, determnine elastic errors and their correction and minimization, and performing the elastodynamics of the system are offered. A three-dimensional isoparametric beam element and matrix exponential method are used to perform the elastodynamics of the cam-link mechanism, determining dynamic stresses, elastic errors, bearing forces, frequencies, and response with and without vibratory motion effects, and furnishing data for the interacting robot. Numerical results for a system are given.

Multi-axis machines are growing rapidly their precision and complexity with the increasing importance of machine intelligence, automation, optimization and safety. It is necessary to identify collision risks and avoid them in manufacturing otherwise production stops may cost a huge amount to the manufacturing company. This study has focused on safe trajectory generation for CNC machines especially focusing on high risked non-functional trajectories. These machines should be able to see any unwilling situation (i.e. collisions) in their vicinity and must be able to detect and react automatically in real-time for safe tool movements. Currently CAM software and some multi-axis machines are able to detect collisions but they do not have any solution to avoid such collisions automatically. The main objective is to make multi-axis machine vision system effective enough that it can see all its activities regarding collisions and can react or command automatically online as well as off-line for real and virtual productions. In presence of obstacles during manufacturing, the proposed approach will provide decisions regarding trajectory correction and improvement automatically. The proposed vision concept is able to take into account the evolution of the scene i.e. the aspects of changes to the obstacle like shape, size or presence during production. The application presented in this paper is for 2D traversal safe online trajectories generation in virtual simulated dynamic environment, which will be adapted to the real-time real machining scenarios at shop-floor by integrating it with STEP-NC technology in future.

Traditional Computer Numerical Control (CNC) machines use ISO6983 (G/M code) for part programming. G/M code has a number of drawbacks and one of them is lack of interoperability. The Standard for the Exchange of Product for NC (STEP-NC) as a potential replacement for G/M code aims to provide a unified and interoperable data model for CNC. In a modern CNC machine tool, more and more motors, actuators and sensors are implemented and connected to the NC system, which leads to large quantity of data being transmitted. The real-time Ethernet field-bus is faster and more deterministic and can fulfill the requirement of data transmission in the high-speed and high-precision machining scenarios. It can provide more determinism on communication, openness, interoperability and reliability than a traditional field-bus. With a traditional CNC system using G/M code, when the machining is interrupted by incidents, restarting the machining process is time-consuming and highly experience-dependent. The proposed CNC controller can generate just-in-time tool paths for feature-based machining from a STEP-NC file. When machining stoppage occurs, the system can recover from stoppage incidents with minimum human intervention. This is done by generating new tool paths for the remaining machining process with or without the availability of the original cutting tool. The system uses a real-time Ethernet field-bus as the connection between the controller and the motors.

Automated packaging machines must be constantly redesigned to accommodate ever changing packing. There is little time to make these changes and no room for error. In this work, computer-integrated design and manufacture of a packaging machine has been conducted. A knowledge base system has been developed, which checks for errors in user input, updates all assemblies per the user input, checks for part interferences in the assembly, holds the new design to accepted design standards, and sends warning messages to the user’s computer screen in the event of a problem. The knowledge base then creates new intelligent part numbers. These part numbers provide the informational link from Engineering to Production as they contain all the new part information needed to make the parts. These part numbers are entered into a program that automatically creates the new tool paths for the CNC mill. The entered part number is automatically milled into the part to insure the correct part was entered. The cost of design and manufacture is then reduced substantially. This knowledge base also extends into sales for quoting and for new job creation which expedites the entire process.

Abstract At present, automatic machines have gradually replaced human labor for improving both the stability and effectiveness of manufacturing operations. Five-axis CNC machine tools are commonly used for traditional surface milling machining. However, it is still necessary to manually reposition the work-piece for the CNC machine tools that enviably lowers position accuracy. As such, it is essential to develop an integrated fusion system that can scan any objects and conduct repair operations automatically. The primary purpose of this research is to integrate the stereo vision system into an existing industrial manipulator. With the proposed method and system, the position error can be reduced by avoiding moving the work-pieces during operations. Also, reconstructing the scan results from multiple views avoids the common blocking problem in vision. Finally, the distance of the manipulator path is optimized by the Hill Climbing algorithm, allowing to create a trajectory of the manipulator end-effector to reprocess the work-piece. In the future, this system can be implemented for automated optical inspection (AOI), such as pipeline maintenance, turbine engine maintenance, and automatic classification of defects.

Full textAbstract:
The mechanical engineering department at Washington State University has just completed a 6 year program in offering a modern sequence of design/manufacturing electives. Using theoretical foundations, site visits, guest lectures, IT based labs, and hands-on manufacturing exercises students learn about the role of information technology and electronic data in modern manufacturing enterprise systems, design for manufacture concepts, design automation, and also hands-on machining using advanced programming concepts of CNC code and CNC machines that are integrated with CAD/CAM systems. In this paper, two key courses of this sequence will be discussed and the innovations that they have enabled in engineering design education of the students will be presented. What is significant is that thru these courses we have achieved a dynamic interplay between the new and the old — we have been able to leapfrog into concepts of modern industry where IT and modern computing tools play a critical role in the manufacturing enterprise system and bring about considerable design and manufacturing automation; at the same time we have also retained and enhanced traditional concepts from before where design engineers had considerable hands-on knowledge with machining and manufacturing processes.

Full textAbstract:
Optimization of manufacturing processes is one of the key challenges towards a sustainable manufacturing environment. The components manufactured nowadays are usually divided into small batches of highly customized parts. These parts are usually machined using the traditional approach for machining on CNC machines. This approach involves the creation of a static G-code for every component that is manufactured, which is dispatched to the machines either manually or through a LAN network. In this paper a new approach in machine tool programming is presented. The proposed system is based on IEC 61499 function blocks to create last-minute feature based code for machining respecting actual machine status. The proposed system optimizes cutting parameters and delivers optimized code with respect to machining time. The function block approach is ideal for on-controller implementation while also allowing through its web based option the embedding into a cloud manufacturing environment. A cloud platform accommodates the machine availability monitoring module for increasing shop-floor awareness and allowing for the correct decisions at the right time. The machining process of face milling was selected as a case study for demonstrating the functionality of the proposed system. The results of the case study are visualized and verified using simulation software.

Full textAbstract:
Rapid Prototyping and Manufacturing (RP&M) technologies are increasingly being applied to produce functional prototypes and directly manufacture small batches of components (where the “prototype” is itself the final product). Although there are various forms of RP&M, almost all rely on a layered manufacturing approach. However despite the flexibility of these systems, they have common drawbacks such as slow build rates, a limited number of build axes (typically one) and the need for post processing, i.e. removal of support structures and finishing. This paper reports the preliminary research that aims to combine sophisticated CAM software and automated assembly technologies to demonstrate that a non-layered method of RP can be engineered. The system under development is referred to as RPBloX. This novel technique has the potential to not only supplement current RP techniques but also act as a standalone method in which products can be brought to market within a shorter design-manufacture cycle time. Essentially, the RPBloX methodology involves a cellular approach to building up a part. Rather than slicing up the CAD model into numerous thin sheets, RPBloX segments the model into 3D cells (or Bloxes) of varying sizes. In contrast to current RP technology, conventional machine tools such as CNC machines and robots are employed for manufacturing and assembly work. Consequently, production costs could be significantly reduced without the forfeiting accuracy and timeliness.

In ASME 2012 International Manufacturing Science and Engineering Conference collocated with the 40th North American Manufacturing Research Conference and in participation with the International Conference on Tribology Materials and Processing.

Full textAbstract:
Compressed air is regarded as the fourth largest utility in the manufacturing industry behind electricity, natural gas and water. It is used in a wide variety of pneumatic, mechanical and maintenance applications in every manufacturing facility. However, very little efforts have been made in trying to monitor and optimize the utilization of compressed air. Hence, a project was conducted to study and analyze the utilization of compressed air under various scenarios that are typical during metal cutting operation in a manufacturing facility. PneuViz application was developed using LabVIEW programming package to monitor and analyze the results. PneuViz was seamlessly linked with the MTConnect data being broadcasted on the corporate network. PneuViz provides drill down capability to analyze cost of compressed air on a per part, per machine, and per customer order. Monitoring the utilization of compressed air by a stand-alone Computer Numerical Control (CNC) machine as well as the overall utilization on the shop floor was facilitated by the use of a sensor system comprising of a flow meter, Data Acquisition Device (DAQ), and a power sensor (load meter). MTConnect was used to enable plug-and-play functionality across the various machines on the shop floor. This was implemented by developing a system of MTConnect adapters that were able to capture the raw sensor data and broadcast it over the Ethernet network. Subsequently, analysis was carried out over various scenarios to determine the cost, energy and carbon footprint impact of the compressed air usage on the manufacturing shop floor.
