1. Benchmark first
That is, the reference surface is processed first. During the machining process of the part, the appearance as the positioning reference should be processed first, so as to provide a precise reference for the subsequent processing as soon as possible.
2. Distinguish the processing stage
The appearance of high precision CNC machining quality requirements is divided into processing stages, which can generally be divided into three stages: rough machining, semi-finishing and finishing. The first thing is to ensure the quality of processing; to facilitate the scientific use of equipment; to facilitate the organization of the heat treatment process; and to find the defects of the blank when it is convenient.
3. Face before hole
For parts such as box body, bracket and connecting rod, the plane should be processed first and then the hole should be processed. In this way, the holes can be positioned on the plane to ensure the azimuth accuracy of the plane and the holes, and it is convenient for the processing of the holes on the plane.
The primary surface finishing processing, such as grinding, honing, fine grinding, rolling processing, etc., should be placed at the end of the process road. The formulation of general guidelines for fine CNC machining roads and the formulation of precision CNC machining regulations can be roughly divided into two links. The first is to draw up the process path for parts processing, and then determine the process scale of each process, the equipment and process equipment used, the cutting standards, and the quota of working hours.
