Contouring with radius compensation
The tool center moves along the contour at a distance equal to the 
radius. “Right” or “left” are to be understood as based on the 
direction of tool movement along the work piece contour as viewed 
from behind a moving tool.
Between two program blocks with different radius 
compensations,  you must program at least one traversing 
block in the working plane without radius compensation 
(G40).
The CNC does not put radius compensation into effect 
until the end of the block in which it is first programmed.
In the first block in which radius compensation is activated 
with, or canceled, the CNC always positions the tool 
perpendicular to the programmed starting or end position. 
Position the tool at a sufficient distance from the first or 
last contour point to prevent the possibility of damaging 
the contour.
