Design and Development of a Camshaft Inspection Machine

Abstract

Camshaft plays a crucial role in the efficiency of reciprocating engines. As it controls the opening and closing of cylinder valves, any flaw in a camshaft translates directly into decreasing the efficiency and life of the engine. Emissions are also increased because of inadequacy of the camshaft. Testing a camshaft, thus becomes an important task. Modern engines with high fuel efficiency require automatic tested camshafts before they can be assembled. A camshaft inspection machine was designed and developed to perform this task. This machine is equipped with highly sensitive linear variable differential transducer (LVDT) which has a resolution better than 0.5μm. Camshafts of Fiat Iveco engine 8035.05 and 8045.05 were inspected on this machine. Their design parameters were measured and logged into a computer system using LabVIEW. The results were studied to validate the accuracy of the developed camshaft inspection machine and found to be satisfactory.
