mastercam后处理文件的修改1（MasterCAM post-processing file changes 1）

mastercam后处理文件的修改1（MasterCAM post-processing file changes 1） Settings and parameter modifications for MASTERCAM postprocessing Mastercam is a set of CAD/CAM software developed by American CNC Software company. The earliest version is V3.0, which can run in DOS system,.V5.0 above, and run in Windows operating system. Because of the birth of early and complete functions, especially in the CNC programming convenient, therefore has a high market share. To construct 2D or 3D graphics CAD function of software architecture, the function of free surface is far better than other similar software. The CAM is more intuitive and convenient, can be directly on the point, line. Generate tool path surface and entity. The following focuses on its post-processing settings Post processing document, referred to as post-processing file, is a file that can be modified by the user in the form of an answer to the question. The extension is.PST. When you install the MASTERCAM system will automatically install the default postprocessing for MPFAN.PST. in the application of Mastercam automatic programming function before, must first of the document for editing, to meet certain needs and habits of users of the NC controller program in performing a postprocessing procedure, if not all correct, it may cause an accident. For example, control the system of a machine tool using G54 series of workpiece coordinate positioning, G90 absolute programming requirements, the previously generated NC program must have a G54G90 setting, if the postprocessing file is set to G55G91, then each generation program contains G55G91, but not G54G90, if in the process without manual correction, it will inevitably cause processing error. This paper introduces the Mastercam postprocessing document content and method and modify settings, providing reference for the related personnel. That is to say A postprocessing procedure can be defined as the controller of the NC program, used by the controller to the FANUC format.
