Positioning Performance Evaluation for Light-Weight Rotary Stage CFRP Application

New energy saving methods are required in the industrial sector to address global climate change and resource depletion. Carbon fiber reinforced plastic (CFRP) has attracted considerable attention as a structural material that can improve energy efficiency by weight reduction. The application of CFRP to machine tools has already been realized; however, the dynamic characteristics of the position control system for CFRP machine tools have not been investigated. In this study, the mechanical properties affecting the positioning performance were experimentally evaluated using a rotary stage that could be switched to different structural materials. This study can be useful as a guideline for position control systems and the mechanical design of a CFRP stage and contribute toward achieving higher energy efficiency.
