The mechanical processing plant formulates the machining process
Machinery factory machine production process refers to the whole process of making products from raw materials. For machine production, it includes the transportation and preservation of raw materials, preparation for production, the manufacture of blank, the processing and heat treatment of parts, the assembly and debugging of products, paint and packaging.
The content of production process is very extensive. Modern enterprises use the principles and methods of systems engineering to organize production and guide production, and regard the production process as a production system with input and output. In the production process, the process of changing the shape, size, position and nature of the production object, so that it becomes a finished product or semi-finished product is called the technological process. It is an essential part of the production process.
Mechanical processing plant can be divided into the casting process, forging, stamping, welding, machining, assembly processes, such as machinery manufacturing process generally refers to the part machining process and machine of the sum of the assembly process, other process is known as the auxiliary process, such as transportation, storage, power supply, equipment maintenance, etc. The technological process is composed of one or several sequential processes, and a process is composed of several working steps. Working procedure is the basic unit of mechanical processing process.
The so-called process refers to a (or a group of) workers, in a machine tool (or a working place), on the same workpiece (or at the same time to several workpiece) of the continuous completion of that part of the process. Constitute the main characteristics of a process is not changing processing objects, equipment and the operator, and the content of the process is continuous, working step is unchanged, machining tools is constant in machining surface, under the constant cutting depth, feed and work schedule, is a processing tool in machining on the surface of a step to complete the work.
To formulate the mechanical processing process of the machinery processing plant, it is necessary to determine the workpiece to go through several processes and the sequence of the process, and only list the name of the main process and its processing sequence of the brief process, known as the process route. The development of the process route is to develop the overall layout of the process, the main task is to choose the processing method of each surface, determine the processing sequence of each surface, as well as the number of industrial order in the whole process, etc.. The process route must follow certain principles.
