Production process

The production process of a machine is the whole process of making a product from a raw material (or semi-finished product). For machine production, it includes the transportation and preservation of raw materials, preparation for production, the manufacture of blank, the processing and heat treatment of parts, the assembly and debugging of products, paint and packaging. The content of production process is very extensive. Modern enterprises use the principles and methods of systems engineering to organize production and guide production, and regard the production process as a production system with input and output.

Source information

(1) Product assembly drawing and parts drawing.

(2) Product acceptance quality standards.

(3) Annual production program of products.

(4) Production conditions of the manufacturer, including specifications, performance and current status of machine tools and process equipment, technical level of workers, capacity of self-made process equipment, power supply and gas supply of the factory and other relevant information.

(5) Design manuals and related standards required by process procedure design and process equipment design.

(6) Advanced manufacturing technology materials at home and abroad.

Step Process:

Step 1. Analyze and study the assembly drawing and part drawing of products.

Step 2.Determine the blank.

Step 3.To formulate the process route, select the positioning base.

Step 4. Determine the equipment used in each process.

Step 5. Determine the tools, fixtures, measuring tools and auxiliary tools used in each process.

Step 6. Determine the technical requirements and inspection methods of the main processes.

Step 7.Determine the processing allowance of each process, calculate the size and tolerance of the process.

Step 8. Determine the cutting dosage.

Step 9. Determine the working hour quota.
