One, machining procedure 1, definition: The craft document that provides product or component workmanship process and operation method to wait calls procedure. Among them, the craft document that provides process of spare parts machining and operation method to wait calls machining procedure. It is to be below specific manufacturing requirement, the most reasonable or more reasonable process and operation method, the form that presses a regulation writes craft document, classics directive production uses after examining and approve. The permutation that each process include in procedure is ordinal, machine dimension, public errand and technical requirement, technological equipment reachs technology measure, cutting dosage reachs the content such as man-hour norm. 2, the action of procedure: (1) the main technique file of directive production: Have direct effect of production; (2) the basis that is manufacturing organization and manufacturing management: Produce a plan namely, attemper, the worker operates the basis that waits with quality inspection; (3) be build or extend factory or workshop are main technical data. Anyhow, the machining procedure of the spare parts is the technical file with every mechanical manufactory or indispensable job shops. Unripe antenatal makes manufacturing preparation with it, manufacturing director is become with it in production, manufacturing hind examines with what it does production. 3, the format of procedure: To get used to the need that industry admits, strengthen science to manage with facilitating communication, former mechanical Ministry of Electronic Industry returns formulate JB/Z187 of guiding technology file.

3, 88 " procedure format " , ask each format that mechanical manufactory presses unified regulation fills in. According to the regulation, those who belong to machining procedure have: 1) machining process card. 2) machining operation sheet. 3) standard spare parts or card of typical part process. 4) odd axis adjusts card from motor-car bed. 5) much axis adjusts card from motor-car bed. 6) machining working procedure handles directive card. 7) examines card. The most commonly used is: Machining process card and machining operation sheet. (1) machining process card: Its format sees next tables.

It is the main technique file of manufacturing management. Suitable scope: Use extensively at be being produced group by group to mix odd a more important part in pre production. (2) machining operation sheet: Its format sees machining operation sheet (click examine specific specification) . The characteristic of this card: The document of a kind of craft that place of every working procedure writes is pressed on the foundation of process card, have working procedure diagram commonly, define requirement of parameter of the treatment content of the each labor situation of this working procedure, craft, operation and place use equipment and tooling to wait. Suitable scope: Basically use at large quantities of mass-produced in all spare partses, the important part in production is being approved in and odd a crucial working procedure in pre production. 2, what procedure design wants source (1) product assembly drawing, part drawing; (2) standard of product acceptable quality; (3) year of production program of the product; (4) semifinished product material and condition of semifinished product production; (5) the manufacturing condition of the manufactory (the specification that includes machine tool equipment and tooling, function and present technical condition, technical level of the worker, the concerned data such as the ability of the ability that the factory abstains tooling and factory power supply, air feed) ; (6) what procedure design, tooling design uses design manual and relevant specification; (7) data of domestic and international advanced production technology. 3, the design principle of procedure (1) the implementation that must make sure all technologies on part drawing paper ask reliably: Assure quality namely, want to improve work efficiency; (2) assure economically rationality: Want cost namely low, use up should small; (3) assure good secure work requirement: Reduce labor intensity of the worker as far as possible, safeguard produces safety, create favorable working environment; (4) should set out actually from this factory: The procedure of place formulate should base oneself upon at this enterprise actual condition, have advanced sex, use new technology, new technology, new data as far as possible. (5) the procedure of place formulate follows a practice examine and of the development of engineering technology and equipment update, should edit ceaselessly perfect. 4, the content that machining procedure designs and measure 1.
