机械制造基础课程设计

1、工艺设计零件（一）1. 工艺分析 图示为一个轴类零件，最大直径为43MM,毛坯可以考虑采用45MM的圆柱棒料，左端的直径小于43MM所以应该采用加工好一端后调头加工的方法。（左端先加工然后调头加工右端）端面加工时，注意恒线速度切削功能的应用，以提高加工质量和生产效率。由于是棒料所以加工时采用三爪卡盘。2.工艺安排根据零件的要求，左端圆柱表面粗糙度要求比较高，所以采用 粗加工-半精加工-精加工的方法加工。端面采用可转位硬质合金90°偏头端面铣刀，轮廓粗、车均采用可转位硬质合金93°偏头外圆车刀。螺纹加工采用可转位硬质合金外螺纹刀，以便采用较高的切削速度，从而提高加工质量和效率

2、，最终切断采用宽4MM的高速钢切断刀。3. 选择车床设备根据零件图样要求，零件外形不是特别复杂，选用经济数控车床即可达到要求。可选用FANUC_0iT型数控车床。4. 确定切削用量查阅附录（一）钢件进给量车端面，主轴转速1500r/min，进给量0.1mm/r；粗车，主轴转速800r/min，进给量0.2mm/r。半精车，主轴转速1000r/min，进给量0.1mm/r。5. 控加工工序卡片数控加工工序卡片产品名称或型号零件名称零件图号轴传动轴Jzz12104车间使用设备FANUC_0iT工艺序号程序编号夹具名称夹具编号三爪卡盘GS53-61工步号工步内容加工面刀具号刀补量主轴转速r/min进
