Abstract:
Development of micro-technology is conditioned by the development of aerospace and automotive industry, medical and military industry. Micro-technologies are being developed in several directions, with the focus on development of micro-machines, micro-tools and development of processes. In micro-machining, all types of materials have problems regard to low machinability, which is especially pronounced in hardened steel.The results of research in this area should provide: overcome the shortcomings of EDM and LBM, as dominant in this area, overcoming problems about productivity, process economy, dimension accuracy. In this paper presents some of the results of research relating to the testing of machinability in micro-milling hardened tool steel AISI D2 (X155CrVMo-5), 62 HRC where analysis of surface roughness and cutter diameter reduction due tool wear was performed.
