A valve lifter is composed of two main parts, a body and a plunger. However, machining accuracy distributions of these parts are considerably different, so the machining dimension must be controlled and adjusted. This paper deals with the behavior of part flow in valve lifer manufacturing systems where a matching method is applied. First, we analyze the effect of combination of machining accuracy distributions and the effect of buffer capacity on the production rate. Next, we analyze the effect of machining lot size and setup time required in dimension control on the production rate, and present the existence of the optimal lot size which yields the maximum production rate. Finally, we propose an approximation method for estimating the optimal lot-size.
