1. The high requirements of CNC machining belong to the precision CNC machining level. The unreasonable processing route will affect the unqualified parts. The processing technology should be divided into three parts: roughing-medium-finishing. If it is a simple mechanical part processing, you can directly use roughing-finishing. In this way, 2 tools can be reduced for processing, and processing time is saved.
2. Whether there is a profile in the area processed by the precision CNC parts, the profile is a real surface, two-dimensional arc, or spline surface. Understand the drawing requirements to choose a reasonable route. This determines whether we use a 2-dimensional toolpath type or a 3-dimensional type. In many cases, both types are required.
3. How to process precision CNC parts when there is a profile, whether it needs to be divided into steep and non-steep surfaces; generally, it is difficult for one tool path to take care of two types of surfaces at the same time, such as in mastercam, surfaces with high profile precision Machining is suitable for steep surfaces. Parallel milling is required for non-steep surfaces. In many cases, it is necessary to add contours to limit the processing area and limit the z-height.
