Abstract
In previous studies, a total removal volume (TRV) unit has been introduced and showed its advantages as the alternative of machining features (MF) in feature-based process planning system. The TRV constitutes a volume that needs to be removed in order to make the product shape. Since the estimation of TRV is based on the actual condition of the raw material, the variety of TRV's shapes are more than the traditional MF definition. Therefore, further machining process plan (MPP) which considers both roughing and finishing is needed. In this paper, a TRV-based generative machining process planning system is proposed. A consideration of the product's geometry and dimension tolerances (GDT) is used for representing both roughing and finishing process. This study is based on milling operation on prismatic shapes.
