Specific principles are.

1, the benchmark first: that is, first processing the reference surface, parts in the machining process, as a positioning benchmark appearance should first be processed, in order to provide a fine benchmark for the subsequent processes as soon as possible.

2, divided into processing stages: machining quality requirements of the appearance, are divided into processing stages, generally can be divided into roughing, semi-finishing and finishing three stages. Mainly to ensure the quality of processing; conducive to the scientific application of equipment; to facilitate the arrangement of heat treatment processes; as well as to facilitate the discovery of defects in the blank.

3, first surface and then hole: for the box, bracket and connecting rod and other parts should be processed first plane after processing holes. This can be positioned with a plane to process the hole, to ensure the accuracy of the position of the plane and hole, and to bring convenience to the processing of the hole on the plane.

4, finishing process: the main appearance of the finishing process, such as grinding, honing, fine grinding, rolling processing, etc., should be placed at the end of the process route stage. The general principles of the development of precision parts machining process route, precision parts machining process protocols, can be divided into two links. First of all, the process route of parts processing, and then determine the process size of each process, the equipment and process equipment used, as well as cutting specifications, work quota.
