Basing on the optical cutting technique, this study aims to develop an accuracy measurement method of tooth profile for minute module gears. This report, as a sequel of the previous report which made possibility of this method clear, deals with subjects with regards to a practical step to actual tooth profile measurements. The object to be measured is a range except tip and root portions of tooth surfaces of a hob-cut spur gear with 0.2 module which is considered to be in measurernent limit in using a touch probe type instrument. Profile errors are acquired in comparison between fine-lined image data of tooth surface filtered through a low pass filter to eliminate influences of surface roughness and so on and the theoretical tooth curve. It is ascertained that adequate measurement results in accuracy of micro meter level can be attained. However, for further development, it is necessary to find solutions for the following problems, namely influences of surface roughness to the image data and use of the polarized light technique.
