14 The Tool Compensation

An auxiliary data is to be introduced

before embarking on the discussion of the details of the compensation computation.

It is """, the angle at the corner of two consecutive blocks viewing from the workpiece side. The direction of "

depends on whether the tool goes around the corner from the left or right side. The control will select the strategy of

going around in the intersection points as the function of angle ". If ">180°, i.e.,

the tool is working inside, the control will compute a point of intersection between

the two interpolations. If "<180°, i.e., the tool is moving around the outside, it may add further straight sections.
