The technological process of the machining plant can also be divided into casting, casting, stamping, welding, machining, installation and other technological processes. The mechanical manufacturing technological process generally refers to the sum of the machining technological process of parts and the installation technological process of machines. Other processes are called auxiliary processes, such as transportation, storage, power supply, equipment repair, etc. The process is composed of one or several processes arranged in sequence, and an operation is composed of several work steps. Working procedure is the basic unit of the machining process.
The so-called process refers to the part of the process that one or a group of workers, on a machine tool or at a job address, complete the same workpiece or several workpieces together. The primary feature of forming an operation is that the processing target, equipment and operator are not changed, and the contents of the operation are completed successively.
To formulate the processing process of the machining plant, it is necessary to confirm how many processes the workpiece will go through and the sequence of the processes. The formulation of the process path is to formulate the overall layout of the process. The primary task is to select the processing method of each surface, confirm the processing sequence of each surface, and determine the number of processes in the entire process. The planning of process path must follow certain guidelines.
