Grinding/Cutting Technology and Equipment of Multi-scale Casting Parts

Abstract Multi-scale casting parts are important components of high-end equipment used in the aerospace, automobile manufacturing, shipbuilding, and other industries. Residual features such as parting lines pouring risers that inevitably appear during process random size, morphology, distribution. The traditional manual processing method has disadvantages low efficiency, high labor intensity, harsh working environment. Existing machine tool serial robot grinding/cutting do not easily achieve high-quality high-efficiency removal residual due to poor dexterity stiffness, respectively. To address these problems, a five-degree-of-freedom (5-DoF) hybrid with stiffness is proposed. Based on it, three types combined offline programming, master-slave control, technologies developed remove small, medium, large parts. Finally, advantages teleoperation solutions elaborated, difficulties challenges discussed. This paper reviews technology provides reference for research multi-scale
