11、在孔加工循环中G98和G99有何区别?
G98:
孔加工循环结束后刀具是返回起始点B;
G99:
孔加工循环结束后刀具是返回参考平面R。
12、如下图所示为一个较为复杂的平面零件,材料为CY12,试编程写其数控加工程序,要求如下:
(1)定加工方案;
(2)选择刀具;
(3)采用镜像加工简化编程
(编程坐标原点设在零件的中心,编程指令采用华中Ⅰ型铣削数控系统)
解:
刀具的选择:
T01:
φ14铣刀加工四个槽
T02:
φ14钻头加工四个φ14的孔
T03:
φ18钻头加工φ18的孔
T04:
φ33钻头加工φ33的孔
T05:
φ10铣刀加工加工其它部分
加工方案:
钻头钻孔→铣刀铣槽→加工加工其它部分(镜像加工)
