Minimum chip thickness in machining MEMS structure using Tool Based Micromilling
Published 2011“…No chip will form if the depth of cut cannot achieve the minimum chip thickness value.The lack of control on minimum chip thickness often leads to the coarse machined surface, poor machining accuracy and difficult in chip removal from the machining zone which leads to burrformation.Hence, the chip formation mechanism should be studied deeply to avoid these problems.In this research WC was elected for tool material and Aluminium Alloy 1100 for work material for the investigation of minimum chip thickness.The experiment is being conducted on a miniature machine known as Microtools Integrated Multi-purpose machine modelled DT-110.The value of chip thickness produced by tool 4.8μmwith3mm/min feedrate,3000rpm cutting speed and 5μm depth of cut.The minimum chip thickness is useful for machining Micro electromechanical System(MEMS) and Bio-MEMSstructures.…”
