In order for the generated NC program to be directly applied to CNC machining, a dedicated post processor must be customized for each CNC machine. This requires the developer to be familiar with the CAM system used and the format of the generated tool path file, familiar with the CNC machine tool and its CNC system code function and its expression format, and this work is intellectually intensive and labor intensive. process. Application example parts: 3D solid punch of ashtray, CAD/CAM software: MasterCAM processing equipment: Huazhong I type CNC ZJK7532A multi-function CNC milling and drilling machine, tool: high-speed steel ball end mill. Main steps: (1) 3D solid figure of ashtray punch ashtray established by MasterCAM. (2) Typical system parameter setting settings. 1 Set the transmission parameter values ​​of the communication interface between the MasterCAM system and the CNC machine tool and other peripherals, such as metric, even parity, transmission format ASCII, transmission rate 1200, read post-processing program; 2 set the master processor system currently used as post-processing program , tool library, material library and other archive files, data paths, etc.; 3 set MasterCAM system to automatically generate NC program related parameters, such as metric, mechanical origin, pattern display mode, program line number, processing report, minimum number of NCI points, etc. Wait. (3) The computer automatically calculates and automatically generates the tool path file, and all the tool path generation is completed. The tool path is shown in Figure 4. (4) Using the 3D entity of the ashtray modeled by MasterCAM, the NC program is automatically generated through the post-processing function of the software: the program above N4600M30, we call the original program, generally can run directly on the CNC machine tool, but due to different CNC machine tools have different CNC systems, and their programming commands and formats are also different. Therefore, they must be slightly modified. We make the following modifications to the original program: 1 Enter the program number after %: the program number consists of four numbers, but not 0000; 2 delete the descriptive statement in parentheses; 3 because the tool and tool change are done manually, Therefore, G20, G21, G17, G49, G28, G43, G54, H3, T3 and other setting statements should be deleted; 4 at the beginning of the program to add workpiece coordinate positioning and quick positioning statement; 5 according to processing needs, the feed rate is changed to F300 ~ between F800. The above modifications are mainly done at the beginning and the end of the program. In addition, the amount of cutting and cutting amount need to be found in the demonstration process through the actual operation of the CNC machine, but the problem is not big. Just make some minor corrections on the value. . Through the trial cutting, the processing of the parts is completed on the wax mold, and the effect is good. Results and significance. In this case, MasterCAM software is used to realize the geometric modeling, tool path generation, tool position verification and tool path editing and post processing. The NC program is automatically generated and processed. Simplify the complex problem. As long as the parameter setting is successful, the system will automatically generate the correct path of the tool, and automatically generate the NC program through the post-processing system, which reduces the error caused by human factors and improves the machining accuracy. Conclusion (1) The editing of post-processing files in this method is based on the application of the automatic programming function of MasterCAM software. The post-processing program defines the NC program of the controller as the format used by Huazhong CNC, and the geometric modeling of the parts. The combination of tool position calculation and graphic display effectively solves the problem of programming data source, graphic display, tool simulation and interactive modification, which makes up for the shortage of CNC language programming. (2) The programming process is performed on the computer directly facing the geometry of the part. It does not require a source program, and is simple, accurate, and intuitive to check. (3) CNC rear-end technology is the key to CAD/CAM integration. For the current use of a variety of CAD / CAM systems, equipped with a variety of machine tools of various types of CNC systems, from CAD to CAM can not be in one step, by manual modification The numerical control program can be applied to different CNC machine tools, which has higher feasibility and practical value. (Finish) Stainless Steel Reversed Dutch Weave
Reverse dutch weave is one of special weave wire cloth used in the filtration field of plastic industry, chemical industry, etc.
Comparing with the normal dutch weave, warp wires are much more than the weft wires in certain unit area, with a larger absolute ratio, so this weave can supply better filtration rate.ustry, etc.
