Machining refers to the process of changing the dimensions or performance of a workpiece by means of a mechanical device. According to the difference in processing mode can be divided into cutting and pressure processing.

The production process of a machine is the whole process of making a product from a raw material (or semi-finished product). For the production of machinery, including the transport and preservation of raw materials, production preparation, rough manufacturing, parts processing and heat treatment, product assembly, and commissioning, painting and packaging and so on. The production process is very extensive, modern enterprise system engineering with the principles and methods of production and production guidance, the production process as a production and output with a production system.

In the production process, all the changes in the shape of the object, size, location and nature, making it a finished or semi-finished product process known as the process. It is a major part of the production process. The process can be divided into casting, forging, stamping, welding, machining, assembly and other process, the mechanical manufacturing process generally refers to the parts of the machining process and the assembly process of the machine, the other process is called auxiliary Process, such as transportation, storage, power supply, equipment maintenance and so on. The process is made up of one or several sequential steps, consisting of a number of steps.

The process is the basic unit that makes up the machining process. The so-called process refers to a (or a group) of workers, in a machine (or a workplace), the same workpiece (or at the same time on a few pieces of work) that part of the continuous process. The main feature of a process is to change the processing of objects, equipment and operators, and the contents of the process is completed continuously.

Step is in the processing of the same surface, processing tools unchanged, the same amount of cutting under the conditions

The knife is also called the work trip, is the processing tool in the processing surface processing once completed step.

To develop the machining process, it is necessary to determine the order in which the workpiece is to be subjected to a few processes and processes. Only the main process names and their processing sequences are listed. The process is called process route.

The process is to formulate the overall layout of the process, the main task is to select the surface of the processing methods to determine the surface of the processing sequence, as well as the number of processes in the process of the number and so on. The route should be formulated in accordance with certain principles.
