Abstract
A coordinate measuring machine and the method of measuring therein wherein the instruction of the geometic shape is prevented from mistaking and the geometic shape of the workpiece is measured without interrupting the joystick operation. The measuring direction of the probe and the measured value of workpiece are taken in the data receiving part. The geometic shape calculation part calculates the errors of each geometic shape based on the measured value from the data receiving part and the formula which was input previously and represents the geometic shape such as "a straight line or circle". And, the geometic shape recognition part compares respective shape errors such as "a straight line and circle" which are calculated in geometic shape calculation part and recognizes the geometic shape having the lowest shape errors. Further, the optimal geometic shape is recognized again based on the geometic shape having the lowest recognized shape errors and the measuring direction of the probe which is input from said data receiving part. Therefore, the step for inputting the geometic shape of the workpiece by the key can be removed before measuring. Moreover, the geometic shape can be rec…
