Abstract

Various processes have been developed to improve the performance of the lubrication oil pump in a recent automobile industry. In particular, trochoidal profile has been widely used for the lubrication oil pump because it is easy to flow control and a lot of oil feed rate is obtained. Accuracy of the trochoidal profile as a core component of the lubricating oil pump affects the driving performance. So, it is necessary to develop efficient processing of the trochoidal profile. In this study, a machining process for the trochoidal profile is developed by turn-mill. Cutting force, surface roughness and tool wear were evaluated in accordance with machining conditions.
