...Hong-Tzong Yau; Lee-Sen Tsou In multi-axis machining of dies and molds with complex sculptured surfaces, numerical control (NC) simulation/verification is a must for the avoidance of expensive rework and material waste. Despite the fact that NC simulation has been extensively used by industries...

... automation of all aspects of the process plan, including operations sequencing, parameter selection, numerical control (NC) code generation, etc. Thus, it becomes possible to go from design to NC code in a fully automated fashion. In the present work we focus on a tightly defined part family, which results...

... extraction fixtures numerical control A modular and progressive approach was implemented to keep the process planner involved in decisions about setups, tool approach, and fixturing. Certain machining features place limitation on fixturing (Cut-Around features) while others limit tool accessibility...
