Abstract
An apparatus for controlling a machine tool which includes a measuring head for measuring a dimension (i.e. a diameter) of a workpiece, a detector for detecting and holding the maximum dimension measured by the measuring head, a circuit for determining the mean dimension of a plurality of measurements, a circuit for determining the dispersion between the measured dimensions and the mean, and a counter for inhibiting the control operation until a predetermined minimum number of workpieces have been measured.
Claims6
An apparatus for controlling a machine tool comprising a measuring head for measuring a given dimension of the successive workpieces machined by the machine tool;
- detecting and storing means for detecting workpieces being measured and storing a signal representing the successive values of the dimensions of the workpieces measured by said measuring head;
- calculating means connected to said detecting and storing means for calculating a mean value of said successive values;
- control means connected to said calculating means for controlling the machine tool;
- and counting means connected with said detecting and storing means, said calculating means, and said control means for receiving information regarding the adjustments made to the machine, and for providing a count signal indicating that a predetermined number of workpieces has been counted after an adjustment, said calculating means having a presettable configuration for accelerating the updating of said mean value after said count signal has been generated.
