Comment
; Loading of tool T1, spindle on with clockwise di-
rection of rotation.
; Absolute dimension input, in rapid
traverse to position XZ.
; Linear interpolation, feed of the tool.
; Counter-clockwise circular interpolation, circle
end point in absolute dimensions, circle center point
in incremental dimensions.
; Traverse
; End of block
Comment
; Incremental dimensions active, traversing in X of 10 mm
(the zero offset is not traversed).
