机械网--螺纹特形轴数控车削工艺设计及编程举例

图示螺纹特形轴,毛坯为φ58㎜×100㎜棒材,材料为45钢。数控车削前毛坯已粗车端面、钻好中心孔。1.根据零件图样要求、毛坯情况,肯定工艺方案及加工线路1)对细长轴类零件,轴心线为工艺基准,用3爪自定心卡盘夹持φ58㎜外圆1头,使工件伸出卡盘175㎜,用顶尖顶持另外1头,1次装夹完成粗精加工(注:切断时将顶尖退出)。2)工步顺序① 粗车外圆。基本采取阶梯切削线路,粗车φ56㎜、SφS50㎜、φ36㎜、M30㎜各外圆段和锥长为10㎜的圆锥段,留1㎜的余量。② 自右向左精车各外圆面:螺纹段右倒角→切削螺纹段外圆φ30㎜→车锥长10㎜的圆锥→车φ36㎜圆柱段→车φ56㎜圆柱段。③ 车5㎜×φ26㎜螺纹退刀槽,倒螺纹段左倒角,车锥长10㎜的圆锥和车5㎜×φ34㎜的槽。④ 车螺纹。⑤ 自右向左粗车R15㎜、R25㎜、Sφ50㎜、R15㎜各圆弧面及30°的圆锥面。⑥ 自右向左精车R15㎜、R25㎜、Sφ50㎜、R15㎜各圆弧面及30°的圆锥面。⑦ 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到达要求。故选用CK0630型数控卧式车床。3.选择刀具根据加工要求,选用3把刀具,T01为粗加工刀,选90°外圆车刀,T03为切槽刀,刀宽为3㎜,T05为螺纹刀养殖户强拆合法吗。同时把3把刀在自动换刀刀架上安装好遇到强拆威胁怎么处理,且都对好刀,把它们的刀偏值输入相应的刀具参数中。4.肯定切削用量切削用量的具体数值应根据该机床性能、相干的手册并结合实际经验肯定,详见加工程序。5.肯定工件坐标系、对刀点和换刀点肯定以工件左端面与轴心线的交点O为工件原点,建立XOZ工件坐标系。采取手动试切对刀方法(操作与上面数控车床的对刀方法相同)把点O作为对刀点农村可耕违建可以强拆吗。换刀点设置在工件坐标系下X70、Z30处。螺纹特形轴
