What are the steps for developing process specifications for Dongguan turning and milling composite machining parts

The process specification for Dongguan turning and milling composite machining parts is the processing method and steps of the parts. His 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 to develop a part process specification 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.

Process procedures are the main process documents that are determined using text, charts, and other carriers to guide product processing and worker operations. It is the basic basis for enterprises to plan, organize, and control production, and is an important guarantee for Dongguan turning and milling composite processing enterprises to ensure product quality and improve labor productivity
