When machining the surface of aircraft and automobile parts, impeller, computer gong, propeller and various curved surface forming molds, the CNC machining center can ensure the accuracy requirements of special-shaped parts and curved surfaces, and greatly improve the processing efficiency. Next, let’s take a look at how the CNC machining center processes the special-shaped parts and curved surfaces?
In the latter, it is the most important to prepare the whole machining process, and the most important thing for the latter is to finish the machining process according to the machining process The most important and important job.
Through the application of UG software in recent years, Shandong Weiwei Heavy Industry Machine Tool Co., Ltd., a manufacturer of CNC machining center, has summed up a set of NC programming methods suitable for all kinds of complex surfaces according to the common technical difficulties in the manufacturing process. The process of computer gong machining includes: establishing mathematical model, determining machining coordinate system, planning cutter location source file, etc.
1、 Establish mathematical model
Before establishing the model, we should first consider the order and method of establishing the features of the model. What should be done first, what should be done later, what method should be used, and what kind of modeling function should be used. This relationship must be properly dealt with when building a mathematical model.
2、 Determine the machining coordinate system
The establishment of solid model is based on working coordinate system, while the generation of machining tool location source file of CNC machining center is based on machining coordinate system. The position of the coordinate origin of the machining coordinate system should be convenient for the processor to quickly and accurately set the tool and to facilitate the size calculation needed in the processing process.
3、 Planning tool location source file
According to the structural characteristics of different product profiles, we can select three processing modules with their own characteristics, such as plane milling, computer gong machining cavity milling and fixed axis contour milling, to plan the machining tool location source files of various types of surfaces.
In a word, we should grasp the application characteristics of each module flexibly according to the different mold surface and contour surface, so that we can process the satisfied products with high quality and efficiency through the CNC machining center.
