Special instances of starting up the radius compensation: If values are assigned to I, J, K in the compensation- selecting block (G41 or G42) - but only to those in the selected plane (e.g., to I, J in the case of G17) - the control will move to the intersection point between the next block and the straight line defined by I, J, K with starting up radius compensation. The values of I, J, K are always incremental ones, the vector defined by them pointing to the end point of the interpolation, in which it has been programmed. This facility is useful, e.g., in moving to an inside corner.
