Mechanical processing (including forging, forging, welding, heat treatment and other skills and equipment, as well as cutting processing skills and machine tools, tools, measuring tools, etc.) has developed rapidly, thus ensuring the supply of various mechanical equipment required for development and production. At the same time, with the increase of production batches and the development of fine processing technology, the processing of fine parts has also promoted the formation of a large number of production methods (part interchangeable production, professional division of labor and cooperation, assembly lines and assembly lines, etc.).
In the process of formulating technical regulations for machining, it is usually necessary to adjust the content that has been determined earlier in order to improve economic benefits. In the process of implementing the technical regulations, unexpected situations may occur, such as changes in production conditions, the introduction of new skills and technologies, the use of new materials and advanced equipment, etc., all of which need to be revised and improved in a timely manner. .
Basic knowledge and planning guidelines for machining:
(1) The planned technical regulations should be able to ensure the processing quality of the machine parts (or the assembly quality of the machine) and meet the technical requirements specified in the planning drawings.
(2) The technical process should have a high yield, so that the product can be put on the market as soon as possible.
(3) Try to reduce manufacturing costs
(4) Pay attention to reducing the labor intensity of workers and ensure production safety.
