Geometric Modeling of Machining
Theory of data structures for representation of geometrical objects within a computer for purpose of virtual investigation of machining processes (Altintas et al. 2005). Only geometric aspects are considered, but investigation of physical processes (e.g., forces or temperatures) is possible as long as they can be derived from geometric data.
Theory and Application
From a strictly geometric view, a machining process can be described as movement of a cutting tool relative to a workpiece. If the track of the tool intersects with the workpiece, the intersected part has to be removed from the shape of the workpiece.
To create a virtual representation of machining processes within computers, a description of the movement as well as geometric models of the workpiece and the tool is necessary. To include the change of the shape of the workpiece caused by intersection of the moving tool, it is necessary to use shape...
