Machining in the production process refers to the entire process of products made from raw materials (or semi-finished products) of. In terms of the machine, including the production of raw materials, transport and storage, production preparation, processing and heat treatment of the blank manufacturing, parts, assembly products, and debugging, paint and packaging content. Content production process is very extensive, with principles of modern enterprise system engineering and production methods and guide the production, the production process as an input and output of the production system. Make the scientific management of enterprises so that enterprises more resilience and competitiveness.
Machining process is the basic unit of the process. The so-called process refers to a place of work, one or a set of artifacts that part of the continuous process is completed. Constitute a process that does not change the main characteristics of the object, equipment and operators, and content is a continuous process to complete. E.g., FIG. 32-1 [cc1] parts, which process can be divided into the following two steps:
Step 1: In the lathe car cylindrical, facing, boring and chamfering the hole;
 Step 2: 6 drill holes in the drill.
 In one process, the workpiece may have to go through several installations. That part of the process of the workpiece in one clamping completed, called the installation. In step 1, there are two installation. First installation: with jaw chuck clamped cylindrical, facing C, boring the hole, the hole chamfering, car cylindrical. The second installation: U-turn with a cylindrical clamping jaw plate, facing the A and B, the hole chamfer.
