Summary: | Compoundmicromachiningisthemostpromisingtechnologyfortheproductionofminiaturizedparts
and thistechnologyisbecomingincreasinglymoreimportantandpopularbecauseofagrowing
demandforindustrialproducts,withanincreasednumbernotonlyoffunctionsbutalsoofreduced
dimensions,higherdimensionalaccuracyandbettersurfacefinish.Compoundmicromachining
processesthatcombinemultipleconventionalandnon-conventionalmicromachiningprocesseshave
the capabilitytofabricatehighaspectratiomicrostructureswithparamountdimensionalaccuracy.
