Explanations
Rapid traverse is performed to point R after positioning along the X and Y axes.
Drilling is performed from point R to point Z. After the spindle is stopped at the bot-
tom of the hole, the tool is retracted in rapid traverse.
Axis switching
The canned cycle must be canceled before the drilling axis can be changed.
Drilling
Drilling is not performed in a block that does not contain X, Y, Z, R, or any other
axes.
