Abstract
It is known that the diameter of cutter must be same as the diameter of the cam follower for the case of cylindrical cam to obtain the precise cam surface. However, if the error is permissible, the smaller size cutter is preferred in the roughing milling process, because the cost of cutter increases exponential fashion. For the case of the cylindrical cam with translating follower, the tool offset and the offset error have been studied. Here a similar methodology to obtain the tool offset of the smaller cutter for a cylindrical cam with oscillating follower is proposed and the offset error is evaluated. The evaluation of error can be useful to determine the minimum size of smaller cutter for finishing milling and grinding processes.
