Improvement of Micro End Milling Tools through Variation of Tool Manufacturing Method and Geometry

Abstract

Micro-cutting offers good potentialities for manufacturing small and medium lot sizes of micro-parts with unrestricted geometry at an economically reasonable expense, either by direct machining or as a means to make moulds for micro injection molding. It yields large removal rates, good compliance with allowances, good surface quality and a wide choice of workpiece materials. Particularly when highly wear resistant materials are to be sculptured, as in mould making for powder injection molding, micro cutting of tool steel is quite an eligible option. With the presentultra-precision drive train, guideways and spindle technology being rather advanced, restrictions to the cutting process efficiency results most of all from the cutting tool itself. Overcoming these shortcomings requires variation of tool material, tool manufacturing method and tool geometry.

Research on Corrosion Resistance of MWEDM Surface with Different Electrical Parameters

“…So research on corrosion resistance of MWEDM machining surface is imperative. Presently research on MWEDM mostly focused on machine tools and processing in China and the world [3][4][5]. There is no report concerned with corrosion resistance of machining work-piece until now.…”

New applications for micro-EDM

“…One possibility is the machining with ion beam, which is a very slow and expensive process. Other experiments were done by Laser beam machining [2].…”

Tool geometry study in micromachining

“…The convenience and value of many products can be substantially increased with reduced size and weight. With the trend towards miniaturization, micromachining becomes increasingly important in fabricating micro parts [1][2][3][4][5][6][7][8][9][10].…”
