Explanations
Rapid traverse is carried out to point R after positioning along the X-- and Y-- axis.
Drilling is performed from point R to point Z. After reaching point Z, cutting feed is
performed back to point R.
Axis switching
Before the drilling axis can be changed the canned cycle must be c anceled.
Drilling
Drilling is not performed in a block that does not contain X, Y, Z, R, or any other
axes.
