Abstract
Calculations of the production program, determine the type of production; analysis of product assembly drawing, the drawings are reviewed; rough determine the type, shape, size and precision; the proposed process route ( dividing the process into the locating datum, choose, select parts of the surface processing methods, processing order of arrangement, selection of machine tools and other equipment ); working procedure design ( the process of determining residual, cutting dosage, process dimension and tolerance, selection of process equipment, computing time quota ); determine process technical requirement and test method of process documents, fill in.
According to the production, technical conditions and the use of the product requirements, from the technology point of view, the part drawings for the following review: drawings view, size, tolerance and technology request of completeness and correctness; processing requirements of the reasonable parts as well as the technology of structure.
Keyword: Process, process, procedure allowance, tolerance
