APPARATUS FOR CORRECTING POSITIONAL ERROR. |
摘要 |
A positional error correction system applicable to numerical control wherein a machine tool is controlled along more than one control axis, such as along X and Y control axes. If the machine tool is to be positionally controlled along the X-axis, the position of the machine tool along the X-axis is corrected by a correction factor decided on the basis of the position of the machine tool along that axis and the position of the machine tool along the Y-axis, whereby a positional correction is effected in a highly accurate manner. The control axes of the machine tool may include a Z-axis and thus are not restricted to merely the X and Y axes. In such case the positional correction is performed using a correction factor decided on the basis of the machine tool position along all three axes. |
