We will explain the basis of machining process from four aspects:
1、 Mechanical manufacturing process, process system and production system
2、 Machining process and composition
3、 Production program and production type
4、 Process specification of machining
First: mechanical manufacturing system, process system and production process
Mechanical manufacturing system is the integration of the equipment used in the manufacturing process, and the goal is to enable the production workshop to effectively and comprehensively complete the parts machining tasks undertaken.
The process system is mainly a whole with specific functions due to the interaction and interdependence between machine tools, cutting tools, fixtures and workpieces in machining.
The production process is the process synthesis of raw materials through certain processing and programming. It is mainly divided into four stages: new product development, product manufacturing, product sales and after-sales service.
Second: machining process and composition
1. Machining process, which mainly refers to the whole process of changing the shape, size, relative position and nature of the blank from workpiece to part.
The composition of the machining process is mainly composed of processes, which are realized by installation, station, work step and tool walking.
Third: production program and production type
The production program mainly refers to the product output and schedule produced by the enterprise within the planned cycle. The production type is the classification of the degree of specialization of enterprise production, which is mainly divided into single piece production, batch production, mass production and so on.
Different production types will lead to differences in production organization, production management, workshop machine tool layout, or blank manufacturing methods, machine tool types, tools, processing or assembly methods, worker skills and so on. Therefore, in the process of customizing the machining process of machine parts or the assembly process of machine products, different production types and characteristics need to be comprehensively considered. In order to improve efficiency and maximize economic benefits.
Fourth: machining process specification
The manufacturing of a part can be carried out by centralizing different processing technologies. Under certain production conditions, determine a more reasonable processing technology and summarize it into documents for production guidance, which is often referred to as the process specification. A reasonable process procedure can effectively ensure the quality of products, improve efficiency, increase efficiency, safety, reliability, economy and rationality.
