Process Specification Design of Shenzhen Machinery Precision Parts Machining

The design principles of Shenzhen machinery precision parts processing:

(1) The designed process specification should ensure the processing quality of the machine parts (or the assembly quality of the machine), meeting the technical requirements specified on the design drawings.

(2) The process should be made more productive 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.

Precision parts processing raw materials:

(1) Product assembly drawings, parts drawings.

(2) Product Acceptance Quality Standards.

(3) The annual production schedule of the product.

(5) The production conditions of the manufacturing plant, including the specifications, performance, and current state of the machine tool equipment and process equipment, the technical level of the workers, the ability of the factory to make its own process equipment, and the ability of the factory to supply power and gas.

(6) Design manuals and relevant standards required for process specification design and process equipment design.

(7) Domestic and foreign advanced manufacturing technology information, etc.

Precision parts processing steps:

(1) Analyze and study the assembly drawings and part drawings of the product.

(2) Determine the blank.

(3) Draw up the process route and select the positioning base surface.

(4) Determine the equipment used in each process.

(5) Determine the tools, fixtures, gauges, and auxiliary tools used in each process.

(6) Determine the technical requirements and inspection methods for each major process.

(7) Determine the machining allowance for each process and calculate the size and tolerance of the process.

(8) Determine the cutting amount.

(9) Determine the working hour quota.
