High-speed steel (HSS) tools are the most commonly used tools in small and medium-scale industry. Cryogenic treatment can be used to enhance the tool life. Studies on cryogenically treated (CT) cutting tools show micro structural changes in the material that can influence the life of the tools significantly. This paper primarily reports performance of CT HSS tools as compared to untreated (UT) ...

High speed machining (HSM) may produces parts with substantially higher fatigue strength; increased subsurface micro-hardness and plastic deformation, mostly due to the ploughing of the round cutting tool edge associated with induced stresses, and can have far more superior surface properties than surfaces generated by grinding and polishing. Cutting edge roundness may induce stress and tempera...

Micromilling is one of the preferable micro-manufacturing process, as it exhibits flexibility to produce complex 3D micro-parts. The cutting forces generated in micro end milling can be attributed for tool vibration and process instability. If are not controlled below critical limits, may lead catastrophic failure tool. Cutting force has a significant role decide surface roughness. Therefore ac...

Placing micro-textures on a tool surface can play an anti-wear and friction-reducing role capture impurities improve the tool-chip friction state, thus improving cutting performance of quality workpiece. To ensure processing in micro-texture-coated tool-cutting process, process parameters micro-texture are limited to smaller parameters, which reduces efficiency increases cost. Aiming at this pr...
