摘要：

Since deburring of components can amount to a considerable cost factor in machining, burr minimization strategies involve the potential of cost reduction. Due to that, they are of great interest for industrial applications. Beside tool geometry, material and cutting data, the applied cooling has an impact on burr formation. In this paper, a cryogenic process cooling with carbon dioxide snow jets is used to influence the burr formation in drilling in comparison to lubricated and dry machining. Burr height, surface roughness, diameter as well as roundness deviation were analyzed for drilling a quenched and tempered steel and an aluminum alloy. (c) 2012 The Authors.
