Develop machining process route general principles machining process planning formulation, it can be roughly divided into two steps. The first is to develop part machining process route, and then determine the step size of each procedure, the use of equipment and process equipment, and cutting specifications, fixed working hours and so on. These two steps are interrelated and should be analyzed. Machining process route is to develop the process to develop the overall layout, the main task is to choose various surface processing methods to determine the sequence of machining various surfaces, and the whole process much number of steps and the like.

General principles of the preparation process route
1, the first processing plane
  Parts in the machining process, as the positioning reference surface should first be processed out of order as soon as possible to provide a baseline for fine machining of the succeeding process. Called "reference first."
2, dividing the processing stage
  Machining high surface quality requirements are divided into the processing stage, can generally be divided into roughing, semi-finishing and finishing stages. Mainly in order to ensure processing quality; conducive to the rational use of equipment; easy to arrange a heat treatment step; and found easy to rough defects.
3, the first surface of the foramen
  For housing, brackets and connecting rods and other parts should be post-processed hole machining plane. So that it can locate a plane machined hole, to ensure the accuracy of the plane and the hole location, but also facilitate the machining hole on a plane to bring.
4, finishing

  Finishing the main surface (such as grinding, honing, grinding \ rolling processing, etc.), should be placed on the final stage of the process route.
