Note
The contour generated in this way is modified by tool radius compensation, which is
activated in the SAR approach block and deactivated in the SAR retraction block.
The tool radius compensation allows for an effective radius of 15, which is the sum of the
tool radius (10) and the contour offset (5). The resulting radius of the tool center path in the
approach block is therefore 10, and 5 in the retraction block.
