Production process The production process of a machine refers to the whole process of making a product from raw materials (or semi-finished products). For machine production, it includes transportation and preservation of raw materials, preparation of production, manufacturing of blank, processing and heat treatment of parts, assembly and commissioning of products, painting and packaging, etc. The content of production process is very extensive. Modern enterprises use the principles and methods of systems engineering to organize and guide production, and regard the production process as a production system with input and output. Working procedure is the basic unit of machining 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 several workpiece at the same time) to complete the part of the process. The main characteristics of a process is not to change the processing object, equipment and operator, and the content of the process is continuous completion of the work step is in the processing surface unchanged, the processing tools unchanged, the cutting parameters unchanged under the condition of the knife, also known as the work stroke, is a processing tool on the processing surface to complete the work step.
To formulate the machining process, it is necessary to determine the workpiece to go through several processes and the sequence of the process. Only the name of the main process and its processing sequence are listed in the brief process, 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 choose the processing method of each surface, determine the processing sequence of each surface, and the number of ordinals in the whole process. The formulation of process route must follow certain principles. Types of production Types of production are generally divided into three categories: 1. Single production: single production of different structures and sizes of products, and rarely repeated. 2. Mass production: The same products are manufactured in batches throughout the year, and the manufacturing process has certain repeatability. 3. Mass production: The number of products made
