Radius compensation
Alternately, you can implement the straight line with radius compensation. The radius
compensation acts modally, therefore you must deactivate the radius compensation again
when you want to traverse without radius compensation. Where several straight line blocks with
radius compensation are programmed sequentially, you may select radius compensation only
in the first program block.
For the first straight line with radius compensation, the tool approaches the starting point
without radius compensation and the end point with radius compensation, i.e. if a vertical path
is programmed, a slope will be traversed. The compensation does not act over the entire
traverse path until the second programmed straight line with radius compensation. The reverse
effect occurs when radius compensation is deactivated.

If you want to prevent deviation from the programmed path, you can program the first straight
line with radius compensation or with deactivated radius compensation outside the workpiece.
Programming without coordinate data is not possible.
