A. Cam is a mechanical device used to transmit motion to a follower by direct contact. The driver is called the cam and the driven member is called the follower. In a cam follower pair, the cam normally rotates while follower may translate or oscillate. The cam is a rotating part that provides reciprocating or oscillating motion to the follower by direct contact. Jumping happens when cam rotates at critical speed above certain value. At jumping, the speed is so high that the follower does not follow the cam and we get a sound of different type. The Cam-Follower material should have good thermal conductivity, thermal resistance and withstand high contact pressures. Friction composites mainly consist of about ten classes of ingredients such as, binder, fibres, friction modifiers and fillers. The proper selection of cam profile is the most important aspect in a diesel engine, as it determines the magnitude of valve lift. Hence in this case study, the cam follower material of Grey Cast Iron is tested with Stainless steel and Al2014. The main objective of the research is to find the alternative material for Grey cast iron so as to reduce the weight and maintain the strength. Hence wear analysis is done on Tribometer for wear rate and wear volume analysis.
