    摘要: A dimension comparator for machine tools is disclosed wherein a first comparator compares a theoretical numerical dimension with an actual dimension as determined by a position measurer. After it is determined that the actual dimension is greater or less than the theoretical dimension, a second comparator compares the actual dimension to a numerical value representing the theoretical dimension plus or minus the numerical value of an aiming interval. This representative numerical value is determined by an adder controlled by the output of the first comparator. In an alternative embodiment, means are provided for controlling the adder to add predetermined increments to the theoretical dimension for comparison in the second comparator.
