Research Abstract	This study aims to develop a systematic construction of process models for elastomer end-milling which are applicable to small-lot production of elastomeric parts. A framework for process identification and process estimation is introduced. In order to implement the proposed framework, model identification methods for an instantaneous cutting force model and a dynamic workpiece deformation model are investigated. A response surface method and dynamic FEA (Finite element Analysis) are applied to identify the dynamic property of elastomeric workpiece. From the comparison between the measured deformation and estimated deformation, it becomes clear that the proposed method can estimate machining process appropriately.
