Abstract

In order to grind a leadscrew of high lead accuracy in the previous studies, it was difficult to install the standard scale on the thread grinder, and furthermore there were some problems about grinding operation in case of in-process control. It is the purpose of this study to realize a new control method for the thread grinder using laser feedback system, to obtain a leadscrew of high lead accuracy and to operate the grinder easily. As a result, the authors obtained a leadscrew of 800mm length which has mean cumulative error of 0.6μm and variance of 4.0μm.
