Mastercam后处理 3+2刀尖跟随源代码

若枫

​Mastercam后处理 3+2刀尖跟随源代码,此方式仅可应用于3+2摇篮5轴，后处理基于MPFan.pst基础上更改测试，无需使用5轴后处理，

1 P; z5 H$ U! I! d# {' I可支持任意位置装夹工件。
5 @' V7 i7 J5 H0 W/ m* J不支持原点平移或坐标偏移。
! h" A8 P: ^1 i$ h4 s: a' _. y( u新建立的加工平面作为绘图平面和刀具平面，原点与WCS基础坐标系重合。
计算宏程序中，#21~#23为C轴旋转中心机械值，#101~#103为A轴旋转中心机械值。
计算宏程序仅支持3+2钻孔、铣削等策略，不支持多轴钻孔、多轴铣削等策略。
G54为基准坐标系，倾斜面的坐标系编号不可为0或小于0。


至于是负解还是正解，这个需要测试。
