摘要
计算生产纲领,确定生产类型;分析产品装配图,对零件图样进行审查;确定毛坯的种类、形状、尺寸及精度;拟定工艺路线(划分工艺过程的级成、选择定位基准、选择零件表面的加工方法、安排加工顺序、选择机床设备等);进行工序设计(确定各工序余量、切削用量、工序尺寸及公差,选择工艺装备,计算时间定额等);确定工序的技术要求及检验方法,填写工艺文件。
根据生产、技术条件和对产品的使用要求,从工艺的角度出发,对零件图样进行如下内容的审查:零件图样的视图、尺寸、公差和技术要求的完整性与正确性;加工要求的合理性;零件结构的工艺性等。
关键词:工序,工艺,工序余量,公差
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 pleteness and correctness; processing requirements of the reasonable parts as well as the technology of structure.
Keyword: Process, process, procedure allowance, tolerance
