Grinding wheel form defining device

Abstract

A grinding wheel form defining device defines a cross-sectional form of a grinding wheel for grinding works, the cross-sectional form including a grindstone axis. Data storage is provided for storing cross-sectional forms of workpieces which are final forms in a grinding process. A grinding wheel basic form selected out of plural prestored grinding wheel basic forms, which are simple two-dimensional patterns for typical grinding wheel forms, is superimposed on a workpiece form which is read out from the data storage. A form obtained by removing the resultant superimposed form from the grinding wheel basic form is defined as a grinding wheel form. Since the grinding wheel form is defined by utilizing the superimposed form obtained by superimposing the already defined workpiece form and the grinding wheel basic form, even a complicated grinding wheel form can be easily and accurately defined. The use of the grinding wheel form defined by the grinding wheel form defining device allows an NC grinding machine to perform accurate grinding simulation, and allows an automatic programming apparatus to generate an accurate part program for dressing.
