摘要

The high hardness of tungsten carbide (WC–Co) material makes it difficult to machine, and when it is machined by the traditional single-point diamond cutting technology (SPDT), the cutting force is high and the machining quality is poor. In-situ laser-assisted machining (in-situ LAM) shows better results in the WC–Co machining process. In this study, we used an in-situ LAM system developed in-house, and the temperature field was solved by analyzing the transmittance of diamond-turning tools through finite element simulations. With cutting force analysis as the main focus, the Taguchi method (TM) was used to optimize the process parameters, reveal the surface formation and damage mechanism of WC–Co in-situ LAM cutting, and construct the regression equation for cutting force prediction.
