Measurement of Machining Center Motion Trajectories within a Small Area

Abstract

This paper describes the authors' recent work which includes : (1) Performing some improvements to make the LM measurement device developed previously applicable to precisely measuring a small size motion trajectory of machining center with high feed rate ; (2) Applying the improved device on a machining center to test circular and linear interpolation motion trajectories within a small area, and discussing the relation of motion accuracy with movement size and feed rate for the machining center. The results of experiments sufficiently demonstrate the effectiveness of the improved LM device.
