Abstract
In machining process planning, delta volume, which is derived by subtracting required shapes from raw material, is decomposed into some elements that are assigned to specific machining features and related to the specific machining processes. Therefore, the removed material of the raw stock, the removal volume, is the key element for deriving the previous shape of raw stock and determining the machining sequence in the machining process planning. It is thought that the removal volume contains information about the shape of the removed material and the machining process. This paper proposes a removal volume model which has the shape of the removed material and the machining process for a machining process plan based on a working tool model derived from the Form-Shaping Function mathematical model of machining operation.
