Summary: In this study, single-factor and central combination high-speed milling tests were conducted on SiCp/Al composites using a PCD tool under cryogenic liquid nitrogen cooling conditions to investigate the surface roughness, surface morphology, surface microhardness, and surface residual stress. The results showed that the surface roughness increased gradually with an increase in feed or milling depth, and the interaction between the two factors aggravated this phenomenon. The surface microhardness and surface residual stress initially increased and then decreased as the milling speed varied from 200 to 360 m/min, indicating that a speed above 240 m/min is recommended for milling under cryogenic liquid nitrogen cooling conditions. Moreover, the degree of surface microhardness significantly improved with an increase in milling depth and feed, and the residual compressive stress tended to convert to residual tensile stress. The simulation results also revealed that the interference effect of SiC particles on internal residual stress transfer increased with an increase in milling depth and feed per tooth, indicating that high milling depths and high feed per tooth should not be used simultaneously.

Summary: This study investigated the surface integrity of titanium alloys machined with Electrical Discharge-Assisted Milling (EDAM), identifying chip layer adhesion as the most common surface defect with the greatest impact on surface quality. Compared to conventional milling (CM), EDAM showed significantly improved surface roughness, smaller residual stress with residual compressive stress, and slightly lower surface microhardness. These improvements are believed to be due to the heat generated by the discharge spark, making EDAM a promising method for efficient machining of titanium alloys.

Summary: In this study, simulation models for Inconel 718 alloy turning under dry and cryogenic machining conditions were developed. The effectiveness of the suggested simulation model was confirmed by comparing the simulation results with experimental results. Cryo reduced the cutting temperature by 9.36% to 11.98% compared to dry cutting. The simulation and experimental results for cutting force showed average differences of 13.73% and 14.63% for main cutting force and feed force, respectively. Response surface methodology was used to build predictive models for cutting temperature and cutting force, which showed excellent performance in estimating these parameters under cryogenic machining settings. Cryogenic machining had a positive impact on the machinability of the alloy by reducing the cutting temperature.
