What are the steps to formulate the process specification of parts for turning milling composite processing
The process procedure of turning milling compound machining parts is the processing method and step of parts. His content includes: arranging the processing procedures (including heat treatment procedures), determining the machine tool, clamping method, measurement method, machining allowance, cutting amount, and man hour quota used in each procedure, and filling in each content on a process card to guide the production and processing process.
The steps to formulate the part process specification are as follows:
1. Process analysis of parts.
2. Selection of blanks.
3. Selection of positioning datum.
4. Formulation of process routes.
5. Select the manufacturing machine tool equipment.
6. Select manufacturing tools, fixtures, measuring tools and other auxiliary tools.
7. Determine the machining allowance, process size and tolerance of the process.
8. Determine the cutting parameters of the process.
9. Estimate time quota.
10. Fill in process documents.
Process procedures are the main process documents that are determined by words, charts and other carriers to guide product processing and worker operation. It is the basic basis for enterprises to plan, organize and control production, and an important guarantee for Dongguan turning milling compound processing enterprises to ensure product quality and improve labor productivity.
