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，
0 i9 n4 k- V, Q1 A! Q  ^/ z* ]

可支持任意位置装夹工件。
/ C# J7 g0 u+ L" D& K- H- p# P不支持原点平移或坐标偏移。
0 E# h' z+ W& c# W4 s! J# I( s  w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。
# a3 c# R9 X. G0 CG54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。
