主 题：Surface-active thermal conductive media(SACM) Finite element model Cutting heat Cutting temperature Inconel 718
摘 要：The heat generated and accumulated on the machined surface of an Inconel 718 workpiece causes thermal damage during the cutting ***-active media with high thermal conductivity coated on the workpiece to be machined may have the potential to reduce the generation of cutting *** this study,a theoretical model for predicting the instantaneous machined surface temperature field is proposed for surface-active thermal conductive medium(SACM)-assisted cutting based on the finite element and Fourier heat transfer *** cutting experiments were performed to verify the results predicted using the proposed surface-temperature field *** SACMs with various thermal conductivities were used to coat Inconel 718 surface to be *** embedded into the workpiece were used to measure the cutting temperature at different points on the machined workpiece surface during the cutting *** experimental results were in agreement with the predicted temperatures,and the maximum error between the experimental results and predicted temperatures was approximately 9.5%.The cutting temperature on the machined surface decreased with an increase in the thermal conductivity of the *** graphene SACM with high thermal conductivity can effectively reduce the temperature from 542℃ to 402℃,which corresponds to a reduction of approximately 26%.The temperature reduction due to SACM decreases with an increase in the distance between the temperature prediction point and machined workpiece *** conclusion,the cutting temperatures on the machined workpiece surface can be reduced by coating with SACM.
