摘要： In a numerical control machine tool, the sliding errors are compensated by control means comprising: a position detector for detecting a current position on a first axis at all times in association with a first-axis position detector; a compensation data memory in which compensation data for a second axis corresponding to positions on the first axis have been stored, the memory outputting a compensation data corresponding to a position which coincides with a current position specified by the position register; a pulse generator means for calculating the difference between the current compensation data and the preceding compensation data and generating a pulse train proportional to the difference; an adder for subjecting to addition or subtraction the pulse train generated and a pulse train obtained by converting the output signal of a second-axis position detector; a pulse restoring means for converting the output pulse train of the adder into a signal similar in form to the output of the position detector; and a compensation control means for outputting as a position feedback signal for the second axis the signal outputted by the pulse restoring means, and for similarly processing the output signal of the second axis position detector to provide as a position feedback signal for the first axis the output signal thus processed.
