Papers by Keyword: Chamfered Tool

Abstract: Due to the high strength of austenitic stainless steels, it is essential for cutting tool to keep with appropriate chamfered edges during the face milling process. In this paper, face milling mechanics with chamfered edge based on cutting force and chip formation were analyzed through finite element analysis (FEA). Three kinds of tools with different chamfered edges were studied on face milling of 1Cr18Ni9Ti austenitic stainless steel. The primary research results indicated that FEA results showed good consistency with experimental results. This can provide references for development and application of tools during face milling process.

Abstract: In this paper, cutting experiment and FEM simulation are combined to investigate the effect of various chamfered edge geometries on cutting force and cutting temperature distribution when hardened steel GCr15(HRC60+2) is machined with PCBN tool. The research results indicate that radial force and main cutting force increase with the enlargement of chamfer angle, and especially, radial force rises more significantly, but radial force is less than main cutting force during the entire cutting process. Cutting temperature also gradually rises as chamfer angle increases, and moreover, it is maximized on the chip-tool interface in a place of 0.1-0.2mm distant from nose.
