Estimation of Power Consumption of Compact Five-Axis-Controlled Machine Tools with Strain Wave Gear Rotary Axes Based on Servo Interior Information

Abstract

In recent years, the need to reduce energy consumption at production sites has been studied because of the increased awareness of environmental problems. In this study, we focus on reduction gear with a strain wave gear incorporated in five-axis machine tools. Utilizing the characteristic of the efficiency varying with temperature, we propose a rotating motion as a warming motion of the swiveling shaft. We investigate the effect of the rotational direction and rotational speed, as well as the energy consumption, after the warmingup operation.
