| Abstract: | Briefly commencing with the independent compensation method of focus location error for 2-dimensional laser cutting, the paper sets out to develop a new superimposing compensation for 3-D laser cutting. The focus location error which is detected by a capacity sensor in the optical head direction will be resolved to x, y and z axis, so that these quantities could be superimposed on the NC interpolation. Thereafter the servo drivers of the machine could simultaneously execute the interpolation and error compensation. |
