Machining production process refers to all of the products made ​​from raw materials (or semi-finished products). In terms of including the transport and storage of raw materials, production preparation, blank manufacturing, processing and heat treatment of the parts, product assembly, and commissioning, paint and packaging machinery production. The production process of a wide range of modern enterprise systems engineering principles and methods to organize production and guide the production, the production process as an input and output of the production system. The scientific management of enterprises can enable enterprises to more strain and competitiveness.
Machining in the production process, directly changing material (or blank), shape, size and performance of the rendering process of the finished product, known as the process. It is a main part of the production process. For example, rough casting, forging and welding; changing the material properties of the heat treatment [1]; machining of parts, all belong to the process. Process is again one or several sequentially arranged in step.

The machining step is the basic component unit of the process. The so-called step is in a place of work, one or a group of workpieces completed that part of the continuous process. The main characteristic is to constitute a step does not change the object to be processed, the equipment and operation, and the contents of the step is continuously completed. E.g. Figure 32-1 [CC1] parts, the process can be divided into the following two steps:

Step 1: lathe cars cylindrical, facing, boring and inner hole chamfering;

Step 2: In a drilling machine to drill apertures 6.

The same procedure, the workpiece may be to go through several installation. That part of the process, known as the workpiece in a single setup completed installation. In step 1, there are two installation. First installation: three-jaw chuck grip cylindrical, car end C, boring bore, the inner hole chamfering, cars cylindrical. The second installation: a U-turn with a three-jaw plate clamped cylindrical, facing A and B, the inner hole chamfering.
