机械制造基础课程设计讲解
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φ43MM,毛坯可以考虑采用φ45MM的圆柱棒料，左端的直径小于φ43MM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，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。

1工艺分析
本零件比较简单，可用工艺版定位加工，先加工上表面，然后加工两个槽，最后打孔。
加工上表面用直径为12的立铣刀加工，然后利用直径为8的立铣刀加工两个槽，最后利用台钻钻孔。
2.走刀路线
采用行切加环切。
（有利于减少空走到时间，提高加工效率）
3.选择机床
根据零件图样要求，工件外形相对简单，容易加工，选用经济型数控铣床即可达到要求。
本次设计选用华中型数控HNC-21M。
