Contour Profile Ring Height Control
- J, i; q, V. ^Shift the tool along its axis to determine contact ring

Contour Profile Floor cleanup passes
•Limit output only to Floor and Wall passes.
•Avoid air cutting of multiple passes Customer value
•Overlap of wall finish operation with the floor finish operation.

五轴等高(Z Level) 套用于等高刀具路径轴。五轴等高刀具路径是平面等高路径，刀轴对路径套用倾斜。五轴等高能使用几种方式套用刀轴倾斜。只有球刀和圆角刀对于这种操作类型有效。
