Experimental Study on Cutting Force in Shear Thickening Polishing for Spherical Steel

Shear thickening polishing (STP) is a finishing process in which the abrasive slurry plays an important role and behaves as a non-Newtonian fluid. In this process, the cutting force are important factors that affect the surface quality of workpiece and machining performance. The cutting force is difficult to calculate accurately because many factors are changed during the STP process. Therefore, experimental modelling for cutting force is proposed in this paper. The influence of polishing speed, abrasive concentration, and working gap on the cutting force were investigated and evaluated by orthogonal experiment method. Experimental results demonstrate that the machining process of the workpiece is significantly improved under suitable cutting force conditions.
