Hard milling is considered to be a precise and efficient machining method for the die and mold manufacturing industry. The main criterion for evaluating the cutting processes of the parts designed for these applications is the quality of the machined surfaces. For this reason, the analysis of the factors that influence the surface roughness obtained in this processes is important for helping the process become more productive and competitive. The present paper presents some results and an empirical model for surface roughness when high speeds face milling of AISI W1 tool steel. The influence of cutting parameters and material hardness is investigated by using Taguchi design of experiments. The results obtained show that high speed face milling of hardened tool steel AISI W1 can be carried out in economical conditions(on plant milling machines) and can lead to satisfactory surface quality (Ra =0.2-0.36 μm).

Components miniaturization in industry leads to intensive research and development of efficient micro-technologies through research of different production processes, machines and tools. This paper presents experimental research on machinability of inclined surfaces on hardened steel workpieces with long-neck micro-end-ball mills. Workpiece is hardened AISI D2 tool steel (X155CrVMo-5). Micro-parts of this material is usually produced by non-conventional technologies such as electro-discharge machining (EDM) and laser beam machining (LBM), that allows machining of 2D or simple 3D structures. The effects of geometrical and cutting parameters on output machinability parameters in ball micro-milling were evaluated. Analysis of tool deflection, surface roughness and tool wedge wear was performed, in order to obtain the recommended cutting parameters for more precise, accurate and quality of micro-parts.

nconel 718 is a typical difficult-to-machine material, and its high speed end milling process has wide applications in manufacturing parts for aerospace and power industry. Surface integrity of these parts greatly influences the final characteristics. This paper presents an experimental investigation to evaluate surface integrity behaviors of Inconel 718 with finishing cutting parameters in terms of surface topography, surface roughness Ra, residual stresses and subsurface microstructure and microhardness. The results show that high cutting speed is advisable to get better surface topography and roughness. Residual stresses and subsurface microhardness barely increase after 80m/min. Microstructure in surface layer has only slight deformation after high speed milling.
