Using CNC machining center to process the surface of these heterogeneous parts, the key work is to work out a reasonable processing program and select the appropriate processing tools. The latter work is relatively simple and can be completed quickly according to the die drawing and process requirements. The preparation of processing program is the most important part of the whole processing preparation work, and also the most important and most important part of the whole die processing One of the main jobs.
1、 Establish mathematical model
Before establishing a model, we should first consider the order and method of establishing each feature of the model, what to do first, what to do next, what method to use, and which modeling function to use. We must deal with this relationship properly when establishing a mathematical model.
2、 Determine machining coordinate system
The establishment of solid model is based on the working coordinate system, while the generation of tool position source file of NC machining center is based on the working coordinate system. The origin position of machining coordinate system should be convenient for rapid and accurate tool setting and dimension calculation.
3、 Planning tool position source file
According to the structural characteristics of different product surfaces, we can select three machining modules, plane milling, cavity milling and fixed axis contour milling, which have their own characteristics and complement each other to plan the machining tool position source files of various types of surfaces.
In a word, we should flexibly grasp the application characteristics of each module according to the processing of mold surface and contour surface, so that we can process our satisfactory products with high quality and high efficiency through CNC machining center.
