ABSTRACT:
A method and apparatus for simulating the processing of a workpiece by boring or milling by an internal computer model in which the workpiece is described by its corner points and surfaces and a bore or a milling process is described by its enveloping contour. The apparatus includes data memories in which information data about the corner points, the surfaces and the enveloping contour are stored. A control mechanism is connected to the data memories for allocating the information to geometric elements that are deposited in work memories and between which a computing mechanism determines intersection points and stores them in an intersection point memory. The control mechanism links the information data about the previous state of the model, the enveloping contour of the milling operation and the intersection points into a description of the workpiece after processing in the internal computer model and brings it into representation on a display unit.
