One of the major problems in machining plane cam with complex curvatures is the machining accuracy of the cam surface. This is due to the deviation of tool tip from theoretical tool trajectory which caused by changing the radial chip thickness. As a solution, in this paper, a new method is proposed to improve the machining accuracy of plane cam. In this method the cutting feed rate which is calculated by considering the radial chip thickness is controlled. This method was applied to two types of cam profiles. The measurements were carried out by using three-axis coordinate measuring machine. The results show that the controlling cutting feed rate improves the machining accuracy of the plane cam than constant feed rate. This is verified by measuring the spindle load. Further more the controlling of cutting feed rate in this method is not affecting on the machining time. Therefore the proposed method is suitable for machining plane cam with complex curvatures.
