The metal machining procedure is one of the process documents that specifies the machining process and use method of parts, etc., which is to write the more reasonable process and use method in accordance with the prescribed form into a process document under specific production conditions, and is used to guide production after approval.

Mechanical processing technical regulations of Shanghai Jingpeng Environmental Technology Co., Ltd. generally include the following contents: the process route of workpiece processing, the specific content of each process and the equipment and process equipment used, the inspection items and inspection methods of the workpiece, the cutting amount, time quota, etc. In the process of formulating process regulations, it is often necessary to adjust the content that has been preliminarily determined in front of it in order to improve economic benefits. In the process of implementing the process regulations, there may be unexpected situations, such as changes in production conditions, the introduction of new technologies and new processes, the application of new materials and advanced equipment, etc., which require timely revision and improvement of the process regulations.

Machining methods are: car, pliers, milling, planing, inserting, grinding, drilling, boring, punching, sawing and other methods. Metal machining can include wire cutting, casting, forging, electric corrosion, powder processing, electroplating, various heat treatment and so on. Car: there are vertical car, sleeping car; The new equipment has CNC car, mainly processing rotary body; Milling: vertical milling, horizontal milling; The new equipment has CNC milling; The main processing groove and shape straight surface, of course, can also be two or three axis linkage processing arc; The main processing shape straight surface, the surface roughness processed under normal circumstances is not high milling machine.

Commonly used machining equipment are digital display milling machine, digital display forming grinder, digital display lathe, electric discharge machine, grinder, laser welding, medium wire walking, fast wire walking, slow wire walking, external grinder, internal grinder, precision lathe, etc., can carry out precision parts of the car, milling, planing, grinding and other processing, such machinery is good at precision parts of the car, milling, planing, grinding and other processing. It can process all kinds of irregular shape parts with processing accuracy up to 2μm.

Process is the basic unit of metal machining process. The so-called process refers to the part of the process that is continuously completed by a (or a group of) workers on a machine tool (or a work place) on the same workpiece (or several workpieces at the same time). The main feature of forming a process is that the processing object and equipment are not changed, and the content of the process is continuously completed.
