14 The Tool Compensation

Unless a point of intersection is found in a linear-to-linear transition, the path of the tool will be:

Fig. 14.5.4-2

Unless a point of intersection is found in a linear-to-circular transition, the path of the tool will be:

Fig. 14.5.4-3

Unless a point of intersection is obtained in a circular-to-linear or circular-to-circular transition, the end of compensation vector in the start point of the first circular interpolation will be connected with the end point of the compensation vector perpendicular to the start point of the second interpolation by a circular arc of uncorrected programmed radius R. Now the center of the interconnecting circular arc will not coincide with the center of the programmed arc. The control will return error message 3047 CHANGE NOT POSSIBLE if the direction change is not feasible even with the relocation of the circle center outlined above.
