Abstract

Micro-holes were fabricated using micro-EDM on the surface of WC/TiC/Co carbide, CaF2 solid lubricants were filled into these micro-holes to form self-lubricating tool (MST). Dry cutting tests on AISI 1045 hardened steel were carried out with the MST tools and conventional tools (CT). The cutting temperature were measured and compared. The results indicated that the cutting temperatures with the MST cutting tools were reduced compared with the CT tools, and the cutting speeds were found to have a profound effect on the cutting temperatures variations of the MST tool. Two mechanisms of cutting temperature decrease are found, the first one is due to the formation of a discontinuous CaF2 lubricating film on the tool rake interface, which may decrease the average shear stress; the other one can be inferred from the microholes on the rake face, which contribute to the reduction of contact length at the tool-chip interface
