Optimal scanning strategy for on-machine inspection with laser-plane sensor

Abstract : The purpose of this paper is to propose a scan path planning method for on-machine measurement (OMM) in a 5-axis machine-tool. Sensor accessibility can be enhanced using the 5 degrees of freedom and the spindle rotation. The laser-plane sensor replacing the cutting tool in the spindle enables to reduce the measurement time and thus allows for rapid decision-making concerning the geometrical conformity of manufactured parts and potential machining corrections. The scan path planning is based on the control of the overlap between two consecutive passes by managing the orientations and the coverage rate of laser beam. Therefore, both scanning quality and scanning time can be controlled by optimizing the overlap zones. In this paper, we adapt the method previously developed for 6-axis robots to a 5-axis machine-tool.
