Minimum chip thickness in machining MEMS structure using Tool Based Micromilling
Tool based micromilling is a promising micromanufacturing technology to produce miniaturized features of about 25μm in size frMEMS and Bio-MEMS applications.It is the most flexible and the fastest way to produce complex three dimensional microcomponents including sharp edges with surface finish at a...
