Obrábění těžkoobrobitelných materiálů

Abstract

This thesis present the design and comparison of two cutting geometries of indexable inserts for turning hard machining material Inconel 625 according to W. Nr. 2.4856. The theoretical part focuses on the characteristics and machinability hard materials and special alloys. The practical part compares the influence of cutting geometry square and round inserts in the machining Inconel 625. Experimental testing was conducted at the outer longitudinal turning on CNC machining lathe Mori Seiki NLX2500. For inserts were set constant cutting conditions. Depending on the depth of cut was evaluated force load, the wear inserts was mapped and measured the roughness of the machined surface. In conclusion, the measured values are evaluated and performed an economic analysis of the individual inserts.
