What process steps are required for mechanical processing?
Jun 08,2020
The formulation of the machining process must confirm how many processes the workpiece will go through and the order in which the processes are completed. Only the main process names and a simple process sequence are listed, which is called the process route. The drafting of the process route is the overall planning of the process, with the main task being to select the processing methods for each surface, determine the processing sequence for each surface, and the number of processes in the entire process. The drafting of the process route must follow certain principles.
The designed process specifications should ensure the processing quality of machine parts (or the assembly quality of machines) and meet the technical requirements specified in the design drawings. The process should have a high production rate, allowing products to be launched into the market as quickly as possible. Efforts should be made to reduce shaping costs, pay attention to reducing the labor intensity of workers, and ensure production safety.
The production conditions of the manufacturing plant include specifications, performance, and current status of machine tools and process equipment, the technical level of workers, the capacity of the factory's self-made process equipment, and the capacity of the factory's power and gas supply, among other relevant materials. Design manuals and relevant standards required for process specification design and process equipment design. Advanced manufacturing technology materials from both domestic and international sources.
Mechanical parts are composed of several surfaces. To study the relative relationships of the surfaces of the parts, a reference must be established. A reference is a point, line, or plane on the part used to determine the position of other points, lines, or planes. Based on the different functions of the reference, it can be divided into design references and process references.
