The characteristics of CNC cutting machine Compared with ordinary lathe, CNC cutting machine has unparalleled advantages: high flexibility. When changing the machining object, it is only necessary to change the program code accordingly, and the hardware (tooling fixture, etc.) hardly needs much adjustment. Conducive to modern management. Realize computer network control and management, processing time, processing conditions are all data, easy to integrate information, and help integrated manufacturing system (CIMS) and enterprise resource management (ERP). At the same time, however, there are also inferior places like ordinary lathes, such as high prices, large initial investment in equipment, and higher requirements for maintenance personnel, technicians and programmers. The main contents and steps of NC programming of NC cutting machine are: analyzing the part pattern to determine the machining process, calculating the value, writing the program list according to the calculation result and the machining route, the proofreading program and the first piece of the CNC machine tool through the control medium input. Trial production. a. Analyze drawings and determine the process. Part drawings and machining process analysis are the basis of CNC programming. Whether it is automatic programming or manual programming, this must be done first. Since the domestic computer-aided process design (CAPP) technology has not yet reached the universal application stage, the work cannot be undertaken by the computer. The programmer needs to analyze the shape, size and technical requirements of the workpiece, and then select the processing plan to determine the processing order. Processing route. b. Numerical calculation. In addition to the point-controlled CNC machine tools (such as CNC drilling and punching), it is generally necessary to calculate the rough and finishing motion trajectory of the part and obtain the tool position data. If the drawing coordinate system is inconsistent with the programmed coordinate system, the coordinates need to be converted. . c. Copy, inspection, trial production. With the development of computer technology, CNC machine tool control media generally have perforated paper tape, magnetic tape, floppy disk, U disk, mobile hard disk or recordable CD. If the graphics are simple and the program is not long, manual data input (MDI) can be used. There are two ways to check. In the early stage, the machine was run empty. The pen was replaced by a pen, the workpiece was replaced by coordinate paper, the machining route was drawn, and then the CRT graphic display was introduced to simulate the cutting process to check whether the motion track is correct, but both. It is impossible to find out the accuracy of the actual workpiece processing, so it is necessary to carry out the first trial production. Flame CNC cutting machine in the application of flame, plasma CNC cutting machine due to its superior performance, has the advantages of manual, semi-automatic cutting can not match, play a huge role in the manufacture of parts. Here is an example: First, a process analysis of the CAD drawings (as described above), which is a drawing of the steel plate (3) in the bottom gate of the coke tank in the localization of the CDQ system, the drawing number is JCY ( first). 02.01.02.01-3, the material is stainless steel 0Cr19Ni10NbN, the thickness of the plate is 16mm, you can see that the roughness of the blank is Ra=50, the rest of the smooth surface is not required, and the drainage holes of 7 35 can not meet the drawing requirements when cutting. Therefore, it is no longer possible (later machining and drilling), taking the amount of bending into consideration to expand the figure, and removing the dimension of the remaining layers. If the length of the board is not enough, it must be stitched in the appropriate position, and finally. The dwg (shown) format is converted to. The dxf (shown) format is saved, which lays the foundation for the next step into CAM programming.
