The machining of complex geometrical shapes with a CNC machine tool requires the determination of cutting conditions namely the depth of cut, the feed rate, the cutter diameter, the number of cutters in use, etc. The number and the diameter of the cutters used for the machining of a given pocket has an important effect on the machining time. Consequently, it is necessary to have an algorithm fo...

IGEL is a new shape modeling tool mimicking heat cutters for 3D computer graphics. Heat cutter is a tool for processing styrene form. Since blades of cutters are steal wires, user can freely bend them. IGEL realizes this operation by a sketch input system. IGEL has two different modes, 2D and 3D modes, and users can switch them freely. In 2D mode, users can draw the shapes of cutters freely. In...
