“…Most of the free-form features introduced in the literature (Park 2000, Shin 1998, and Storr 1995 are concerned with machining applications. This study assumes that the die surface is visible from above (Le., no "negative draft" in the die surface) and that NC machines can perform all 3-axis machining operations.…”

Abstract:This paper proposes a hierarchical CAPP (computer automated process planning) system architecture for die cavity machining. The CAPP system structure has been developed on the basis of the current practices of die cavity machining and is composed of five modules -Form EDM, Clean-up, Finish, Semi-finish, and Roughing planning. The individual CAPP modules are connected in a sequential manner. They are identical in structure and each module consists of four sub-functions forJeature extraction, process planning, machined surface update, and NC-code generation. Input to the CAPP system are 1) a CAD model of the die surface geometry, 2) the geometry of the raw stock, and 3) a set of available cutting tools with machinability data. Output from the CAPP system is a set of NC-codes. A process plan example, which is generated by a prototype CAPP system developed on the proposed structure, shows that the proposed CAPP architecture is practical and valid in the die cavity machining.

“…It is only performed with limited consideration of the characteristics of the actual feature, the applied tool and the respective process type, since no appropriate information is available in common G & M code. To address the limited information availability on the shop floor and especially in the CNC, worker-oriented machining models have been developed in the middle of the1990s which combine manufacturing features and machining operations into machining objects (Storr et al 1995). Since these machining models usually had to be converted to G & M code, the corresponding machining objects were available on Human Machine Interface (HMI) level only, but not transferred to the CNC kernel.…”
