Popis: A method for inspecting a pinion type cutter using a coordinate measuring machine (CMM) is proposed. In this method, the cutting edge profile of the cutter is indirectly measured as the intersecting curve between the flank of tool and the cutting face. Left and right side flanks of the cutter are considered to be the tooth surfaces of two different involute helical gears. The coordinates of a large number of points on the tooth surface and the face are measured with CMM. The tooth surface and the face are estimated from the measured data by the method of least squares. The cutting edge profile is calculated from the estimated tooth surface and the face. While the cutting edge profile is moved helically along a helinx of an imaginary gear which should be generated by the ideal cutter, it forms the tooth surface of the imaginary gear, and a pressure angle of this gear can be calculated. Pressure angle error of the pinion cutter is the imaginary gear's one.
