Steps for formulating part processes in precision parts processing

The process regulations for precision parts processing are the processing methods and steps of the parts. Its content includes: arranging machining processes (including heat treatment processes), determining the machine tools used in each process, clamping methods, measurement methods, machining allowances, cutting amounts, and working hours, etc., and filling out each content on a process card to guide the production and processing process.

The steps for formulating process specifications for precision parts processing are as follows:

1) Conduct process analysis on the parts.

2) Selection of blanks.

3) Selection of positioning reference.

 

4) Formulation of process routes.

5) Choose to manufacture machine tool equipment.

6) Select manufacturing tools, fixtures, measuring tools, and other auxiliary tools.

7) Determine the machining allowance, process dimensions, and tolerances for the process.

8) Determine the cutting amount for the process.

9) Estimate time quota.

10) Fill in the process documents.
