Specific procedures Custom Machining Technology
Step machining process to develop procedures
1) Calculation of the production program, to determine the type of production.
2) Analysis of part drawings and product assembly drawings of parts for process analysis.
3) Select the blank.
4) the elaboration process route.
5) determine the allowance machining step, a step to calculate dimensions and tolerances.
6) determine the equipment and tools, fixtures, measuring tools and aids used by each process.
7) determining the amount of cutting and fixed working hours.
8) determine the technical requirements and test methods for each major step.
9) Fill process documents.
In the development of machining process planning process, often on the front has been preliminarily determined content adjusted to increase economic efficiency. During the execution process of order, it may occur before the case is not expected, such as the introduction of changes in production conditions, new technologies, new processes, new materials, the use of advanced equipment, require timely revised and improved process planning .
