 1．根据零件图样要求、毛坯情况，确定工艺方案及加工路线     1）对细长轴类零件，轴心线为工艺基准，用三爪自定心卡盘夹持φ25㎜外圆一头，使工件伸出卡盘85㎜，用顶尖顶持另一头，一次装夹完成粗精加工。     2）工步顺序     ① 手动粗车端面。     ② 手动钻中心孔。     ③ 自动加工粗车φ16㎜、φ22㎜外圆，留精车余量1㎜。     ④ 自右向左精车各外圆面：倒角→车削φ16㎜外圆，长35㎜→车φ22㎜右端面→倒角→车φ22㎜外圆，长45㎜。     ⑤ 粗车2㎜×0.5㎜槽、3㎜×φ16㎜槽。     ⑥ 精车3㎜×φ16㎜槽，切槽3㎜×0.5㎜槽，切断。     2．选择机床设备     根据零件图样要求，选用经济型数控车床即可达到要求。故选用CK0630型数控卧式车床。     3．选择刀具     根据加工要求，选用五把刀具，T01为粗加工刀，选90°外圆车刀，T02为中心钻，T03为精加工刀，选90°外圆车刀，T05为切槽刀，刀宽为2㎜，T07为切断刀，刀宽为3㎜（刀具补偿设置在左刀尖处）。     同时把五把刀在自动换刀刀架上安装好，且都对好刀，把它们的刀偏值输入相应的刀具参数中。     4．确定切削用量     切削用量的具体数值应根据该机床性能、相关的手册并结合实际经验确定，详见加工程序。     5．确定工件坐标系、对刀点和换刀点     确定以工件右端面与轴心线的交点O为工件原点，建立XOZ工件坐标系，如图2-17所示。     采用手动试切对刀方法（操作与前面介绍的数控车床对刀方法基本相同）把点O作为对刀点。换刀点设置在工件坐标系下X35、Z30处。     6．编写程序（以CK0630车床为例）     按该机床规定的指令代码和程序段格式，把加工零件的全部工艺过程编写成程序清单。该工件的加工程序如下：                                      N0010  G59  X0  Z105         N0020  G90                            N0030  G92  X35  Z30  N0040  M03  S700 N0050  M06  T01 N0060  G00  X20  Z1                                  N0070  G01  X20  Z-34.8  F80 N0080  G00  X20  Z1    N0090  G00  X17  Z1 N0100  G01  X17  Z-34.8  F80 N0110  G00  X23  Z-34.8                     N0120  G01  X23  Z-80  F80 N0130  G28           N0140  G29 N0150  M06  T03      N0160  M03  S1100                                     N0170  G00  X14  Z1  N0171  G01  X14 Z0           N0180  G01  X16  Z-1  F60 N0190  G01  X16  Z-35  F60 N0200  G01  X20  Z-35  F60 N0210  G01  X22  Z-36  F60 N0220  G01  X22  Z-80  F60 N0230  G28 N0240  G29 N0250  M06  T05             N0260  M03  S600            N0270  G00  X23  Z-72.5   N0280  G01  X21  Z-72.5  F40 N0290  G04  P2 N0300  G00  X23  Z-46.5      N0310  G01  X16.5  Z-46.5  F40           N0320  G28      N0330  G29   N0340  M06  T07                 N0350  G00  X23  Z-47           N0360  G01  X16  Z-47  F40 N0370  G04  P2 N0380  G00  X23  Z-35 N0390  GO1  X15  Z-35  F40 N0400  G00  X23  Z-79 N0410  G01  X20  Z-79  F40 N0420  G00  X22  Z-78  N0430  G01  X20  Z-79  F40 N0440  G01  X0  Z-79  F40 N0450  G28 N0460  G29 N0470  M05 N0480  M02
