Toolpath planning method with the constraint of cutting force fluctuation in slow tool servo turning for complex curved surface parts

Parts with the complex curved surface are commonly used in high-end equipment. The machining quality of parts is important for property With position control main spindle, i.e., C axis, slow tool servo (STS) turning a very promising technique to effectively machine parts. However, restricted by cutting force fluctuation finishing turning. Hence, STS toolpath generation approach constraint proposed this study. As proportionate area, area surfaces analyzed and calculated. Then functional relation between feed rate derived. Based on geometrical characteristic first revolution toolpath, optimized small derive cutter contact points (CCPs) cylindrical coordinate system. From validation experiment results, it can be seen that fluctuation, profile tolerance, roughness reduced, part machined planning method 17.625 nm. Thus, study provides guidance surface.
