Manufacturing Processes
制造工艺研究将原材料转变为机械产品的各种加工方法与工艺规律，是机械工程的核心专业课。内容包括铸造、锻造、焊接、冲压等成形工艺，车削、铣削、钻削、磨削等切削加工工艺，特种加工（电火花、激光、增材制造）以及机械加工工艺规程编制与装配工艺。学生将掌握工艺路线拟定、工序尺寸计算、加工精度与表面质量控制等工程能力。
Manufacturing Processes studies methods for converting raw materials into mechanical products, a core course in mechanical engineering. Topics include casting, forging, welding, and stamping; turning, milling, drilling, and grinding; special processes (EDM, laser, additive manufacturing); and process planning and assembly. Students master process route design, dimensional calculations, and quality control.
给定一个典型零件（如阶梯轴或箱体类零件）的零件图与生产批量，学生需进行零件工艺分析，选择毛坯，拟定工艺路线，确定各工序的加工余量、工序尺寸及公差，选择机床、刀具、夹具与量具，并计算切削用量与工时定额。最终编制完整的机械加工工艺过程卡片及关键工序工序卡片各一份。
Given the drawing and batch size of a typical part (shaft or housing), students perform process analysis, select the blank, plan the process route, determine machining allowances, dimensions and tolerances for each operation, select machine tools, cutting tools, fixtures, and gauges, and calculate cutting parameters and time quotas. Submit complete process route sheets and key operation sheets.
