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.

Mesin CNC salah satu teknologi yang masih dikembangkan untuk peningkatan kegiatan produksi salah satunya mesin CNC 3 axis dengan fungsi milling. Pada umumnya kontrol utama mesin CNC menggunakan salah satu board dari platform resmi yaitu Mach3 dengan fitur yang sangat mendukung untuk fungsi sebuah mesin CNC salah satunya komunikasi paralel untuk menunjang kinerja mesin CNC tetap stabil, akan tetapi komputer dengan fitur komunikasi paralel umumnya tipe lama dengan spesifikasi rendah yang hanya bisa dijadikan sender dan tidak bisa digunakan untuk mendesain. Berdasarkan permasalahan tersebut maka diperlukan peningkatan efisiensi dalam memanfaatkan teknologi CNC yaitu dengan menggunakan platform yang bersifat open source dan menggunakan komunikasi serial untuk menjadikan teknologi CNC lebih fleksibel dalam hal pengoperasian dengan satu komputer dapat digunakan untuk mendesain dan sender. Arduino Uno salah satu platform yang bersifat open source yang dapat dimanfaatkan untuk menjadi kontrol utama mesin CNC. Hasil penelitian mesin CNC berbasis Arduino menunjukan bahwa penerapan komunikasi serial untuk pengoperasian mesin CNC memiliki perfomansi dan akurasi yang tidak jauh berbeda dengan mesin CNC yang menggunakan komunikasi serial. Dalam parameter jumlah objek yang dikerjakan sama Mach3 30 detik lebih cepat dengan akurasi kesalahan 0,05% dan Arduino 0,1%. Dalam parameter jumlah waktu yang sama yaitu 30 menit Mach3 menyelesaikan 8 objek dan objek ke - 9 hanya dikerjakan 25,6%, Arduino menyelesaikan 8 objek dan objek ke – 9 hanya 14,5%.

The contouring precision of computer numerical control (CNC) machine tools relates to whether the dynamic performances among all the axes match or not. In general, the cross-coupled controller (CCC) is a more efficient approach to enhance contouring precision than single-axis servo controller. Note that the contouring error CCC can not be separated from pathway programming in multi-axis linked servo system. In order to obtain satisfied contouring precision, the CCC approach connected with non-uniform rational basis spline (NURBS) curve interpolation is researched in detail in the paper. Above all, an "arc approximation algorithm" contouring error computing model is developed, according to the real cutter positions from each axis feedback and the interpolation dots stored in the interpolation buffer. Then the contouring error correction quantity PI control and distribution algorithm is put forward by introducing a zoom coefficient. The contrast experimental results on the CNC experiment table show that the developed CCC approach can reduce contouring error and improve tracking performance further.

Three different and complementary ways of adaptive control are presented, each working on a different time scale. All three of them are made possible due to evolutions and developments in CNC controls. The first and most popular way of adaptive control is adaptive process control. Since the process variables in sheet metal equipment change significantly in milliseconds, the control loop must also perform on a sub second time scale. The second adaptive loop is adaptive production control. Modern CNC controls know what they are manufacturing and talk with higher production software. Instead of just executing a planning that came top down, the CNC has enough knowledge of its environment that it can propose an intelligent job sequence and hence react more effectively on unforeseen situations. These adaptive loops perform on a time scale of hours and days. The third adaptive loop is adaptive resource control. To produce sheet metal parts, we need several kinds of resources: human resources, material, consumables, energy and equipment. CNC sheet metal equipment is a considerable investment. However most production managers do not know how effective their resources are being used. By applying the principles of overall equipment effectiveness, we can close the resource control loop. This loop performs on a time scale of weeks and months.

Abstract. By analyzing the current open software architectures for PC-based master-slave Computer Numerical Control(CNC) systems and soft-CNC systems, this paper put forward a multi-platform compatible open software architecture for the two types of CNC systems. The architecture is composed by five different function layers: CNC presentation Layer, CNC Business Layer, CNC Data Layer, NC Interface Layer and NCK Layer. Firstly, the WPF and the MVVM pattern decouple the User Interface (UI) presentation and business logic. Secondly, the component technology is used to decouple the business logic and Numerical Control(NC) functions. Thirdly, the implementation of NC tasks is put into non-RT environment and RT environment. The experiment results of developing the application based on the architecture show that the layered software architecture improves the maintenance and development efficiency, and running the application in the “non-RT+RT” environment proves that the architecture is available for PC-based master-slave CNC systems and soft-CNC systems.

Direct numerical control is also known as distributed numerical control (also abbreviated DNC), is a common manufacturing term for networking CNC machine tools. On some CNC machine controllers, the available memory is too small to contain the machining program (for example machining complex surfaces), so in this case the program is stored in a separate computer and sent directly to the machine, one block at a time. If the computer is connected to a number of machines it can distribute programs to different machines as required. Usually, the manufacturer of the control provides suitable DNC software. However, if this provision is not possible, some software companies provide DNC applications that fulfill the purpose. DNC networking or DNC communication is always required when Computer-Aided Manufacturing (CAM) programs are to run on some CNC machine control. Wireless DNC is also used in place of hard-wired versions. Controls of this type are very widely used in industries with significant sheet metal fabrication, such as the automotive, appliance, and aerospace industries. A DNC system has to fulfill two basic tasks such as first guaranteeing secure, timely data transfer from and to the CNC controllers, secondly administering many thousands of NC programs.

An automatic tool-setting and workpiece online detecting system was proposed to study the key technologies of next-generation intelligent vision computerized numerical control (CNC) machines. A computer vision automatic tool-setting system for a CNC machine was set up on the basis of the vision tool-setting principle. A rapid vision calibration method based on the position feedback from the CNC machine was proposed on the basis of the theory of traditional vision system calibration. The coordinate mapping relationship of the image and the CNC machine, the tool-setting mark point on the workpiece, and the tool tip were calibrated. The vision system performance testing and system calibration experiments were performed. Experimental results indicated that the time consumption was 128 ms in image processing. The precision of tool setting and measuring was less than 1 μm. The workpiece positioning and processing online detection function of the system can completely meet the requirements of visual CNC machine application, and the system has wide application prospects.

A Unified Reconfigurable Open Control Architecture (UROCA) aims at unifying the reconfiguration aspects and managing the interaction amongst the different operating levels of individual machining control systems that are likely to perform in reconfigurable manufacturing systems. The hierarchical control structure of UROCA demands the usage of a supervisory control scheme in order to manage operations of supervisory and servo controllers altogether into a reconfigurable control process. The main function of the supervisory unit is to serve as a switching/reconfiguring logic amongst different available controllers, according to need, in order to maintain motion output within the permitted limits. Due to backlash, efficiency of machine tools will be undesirably turned down causing higher vibrations, lower contouring accuracy, and may draw the whole system into instability region. A Switching control scheme designated to manage the control process where two different controllers with two different control functionalities, acting differently in two vital zones - one of them where the backlash lies, and the other when moving past the backlash - is the main topic of this paper. The proposed switching schemes emphasize a reconfiguration aspect on the control process level for machine tools as perceived, investigated and resolved by the physical and control layers located at the deliberative part of the UROCA architecture.

Mutational analysis of cap'n'collar (cnc), a bZIP transcription factor closely related to the mammalian erythroid factor NF-E2 (p45), indicates that it acts as a segment-specific selector gene controlling the identity of two cephalic segments. In the mandibular segment, cnc has a classical homeotic effect: mandibular structures are missing in cnc mutant larvae and replaced with duplicate maxillary structures. We propose that cnc functions in combination with the homeotic gene Deformed to specify mandibular development. Labral structures are also missing in cnc mutant larvae, where a distinct labral primordia is not properly maintained in the developing foregut, as observed by the failure to maintain and elaborate patterns of labral-specific segment polarity gene expression. Instead, the labral primordium fuses with the esophageal primordium to contribute to formation of the esophagus. The role of cnc in labral development is reciprocal to the role of homeotic gene forkhead, which has an identical function in the maintenance of the esophageal primordium. This role of homeotic selector genes for the segment-specific maintenance of segment polarity gene expression is a unique feature of segmentation in the preoral head region of Drosophila.
