In recent years, research on mobile machine tools for the precise processing of large workpieces has been carried out, but they have been revealed to have low structural rigidity and low precision. In this study, we designed and fabricated a contactless chromatic confocal 2D/3D machined shape measuring head capable of robust vibration and high-speed measurements to improve the machining accuracy of mobile machine tools and the workpiece machining origin recognition head capable of finding the workpiece machining origin. In addition, the accuracy of the machining profile measurement and workpiece origin recognition accuracy was evaluated experimentally under various environmental conditions such as workpiece inclination, lighting conditions, and workpiece surface conditions. The experimental results demonstrated that the machining profile measurement accuracy was 18.6 ㎛ and the machining origin recognition accuracy was below 60 μm. KCI Citation Count: 0
