Intensive Development

The development of industry in the last ten years has caused the production of parts with relatively small dimensions. This has led to intensive development of efficient micro-technologies through research of processes, machines and tools. This paper presents the research of machinability, channels micro-milling in AISI D2 tool steel (X155CrVMo-5), hardened to 62 HRc. As the tool is used micro-milling cutter with diameter of 0.6 mm and relatively large working length of 5 mm. Analysis of surface roughness, burr on workpiece edges and reduction of cutter diameter due tool wear was performed.

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.

This work is a contribution in analyzing structure, tribological behavior and corrosion of AISI L6 hardened tool steel. Structural characterization and tribological behavior of steel were investigated using Optical Microscopy (OM), Scanning electron microscopy (SEM), wear testing by friction on a pin-on-disc Tribometer and corrosion by potentiodynamic polarization. Comparing to the as-received steel, hardening has generated a fine martensitic microstructure causing a 1.5 times hardness increase. Hardening has contributed to improvement of wear resistance as the coefficient of friction has decreased from 0.86 to 0.67μ. An increase in corrosion resistance was observed after hardening treatment.

Cutting Processes

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).
