In the production process, the process of changing the shape, size, location and nature of the production object to make it a finished or semi-finished product is called a process. It is the main part of the production process. The process can be divided into casting, forging, stamping, welding, machining, assembly and other processes.
The mechanical manufacturing process generally refers to the sum of the machining process of the parts and the assembly process of the machine. Other processes are called auxiliary processes. Processes such as transportation, storage, power supply, equipment maintenance, etc. The technological process is composed of one or several sequential processes, and a process consists of several work steps.
Process is the basic unit that constitutes the machining process. The so-called process refers to the part of the technological process that a worker (or a group of) continuously completes on a machine tool (or a work site) for the same work piece (or several workpieces at the same time). The main feature of a process is that it does not change the processing objects, equipment and operators, and the content of the process is completed continuously.
The working step is under the condition that the processing surface is unchanged, the processing tool is unchanged, and the cutting amount is unchanged. The pass is also called the working stroke, which is the work step completed by the machining tool on the machined surface once.
To formulate the machining process, it is necessary to determine the number of processes that the workpiece will go through and the sequence in which the processes are carried out. Only a brief process of the main process name and its processing sequence is listed, which is called the process route.
The formulation of the process route is to formulate the overall layout of the process. The main task is to select the processing method of each surface, determine the processing sequence of each surface, and the number of processes in the entire process. The formulation of the process route must follow certain principles.
