Abstract

Maximum products created on elastomers are shaped by some kind of molding and curing process. This paper deals with an innovative method of elastomer machining. End milling experiments were performed with an end milling tool for three speeds, constant feed and depth of cut, and two workpiece temperatures. A Fixture is designed to hold rigidly the elastomer workpiece, because of its relatively low elastic modulus. The objective of these experiments was to better understand the basic machinability of elastomers in dry and cryogenic condition and to examine the influence of cryogenic cooling and circumstances that produce clean and burr-free surfaces in elastomers. From experimental data it can be noticeably seen that increase of cutting force become more significant with higher cutting speeds for cryogenic end milling. Cryogenic end milling presented remarkable improvement in machinability compared to ambient end milling.
