A toothed wheels has single pitch error, tooth profile error, run-out and so on. When the accuracy of a toothed wheels is inspected, base-circle-disk method is recorded as pressure angle error when the disk diameter has an error. A toothed wheels was inspected with different-sized disk diameter. And with its record, the dispersion and bias of pressure angle was compared by using the manual for involute-profile-measuring machine and the dizitizer. The results are as follows: 1) The result of using the manual for involute-profile-measuring machine and the digitizer shows that a high precision gears has a little dispersion and bias of pressure angle. 2) When a low precision gears are inspected, the result of analysis value by using the digitizer shows less dispersion and bias of pressure angle than when the manual method is used. 3) If the disk diameter has a large tolerance, pressure angle will have more accurate value when pressure angle error is analyzed by the digitizer.
