Refers to the production process of the machine is made of the entire process from raw materials (or semi-finished products) of. Machine production, including raw materials in terms of transportation and storage, production preparation, processing and heat treatment of the blank manufacturing, parts, product assembly, and commissioning, paints and packaging content. Content production process is very extensive, with the principles of modern enterprise system engineering and production methods and guiding production, the production process as a having an input and an output of the production system.

In the production process, any changes in the shape, size, location and nature of the production of objects, making the process finished or semi-finished products called process. It is a major part of the production process. The process can be divided into casting, forging, stamping, welding, machining, assembly and other processes, machinery manufacturing process generally refers to the sum of the assembly process of machining processes and machine parts, and other process is called secondary process, such as transportation, storage, power supply, equipment maintenance. In turn processes the order of one or several steps consisting of a step of the step has several components.

Process step is the basic unit consisting of machining process. It refers to a so-called step (or a group) of workers in the (or a place of work) a machine on the same workpiece (or simultaneously to several artifacts) to complete that part of the continuous process. It constitutes a step of the main characteristics of the object does not change the process, equipment and operators, and content is a continuous process completed,，In the surface processing step is the same, the same processing tool, cutting the amount under the same conditions. Pass known as the working stroke, it is a working tool completed step on the machined surface.

Development of machining process, you must determine the workpiece to go through several processes and process sequence performed, list only briefly the main process step name and processing order process called routing.

The process route is to develop the overall layout of the development process, the main task is to select the respective surface processing methods to determine the processing order of the respective surface, and the whole process step number much like. Process route to be followed to develop certain principles.
