摘要：
The invention relates to servo-driven computer-numerically-controlled systems of the type adapted to receive part program instructions defining a desired path [110] of relative movement between a tool [12] and a workpiece [W], wherein the path may include an interior or exterior curved portion to be effected by coordinated linear movement of machine members along at least two orthogonal linear axes [X,Y]. The invention provides apparati and methods for correcting path radius errors [E] to facilitate rapid and accurate movement along the curve. The invention carries out path radius correction by generating position commands [52,53,54 and 55] received by the servo [69] using corrected radius data [46], the difference between which and the desired radius [R] to be machined compensates for at least a portion of the path radius error [E] that would otherwise be generated by the servo [69].
