Patent FR-2722719-A1 (FR)
Title: Method of control of machine tool
Inventor: HUMBERT BRUNO
IPC: G05B19/401
Filed: 1994-07-20
Abstract: The machine tool control method commences with measurement of a previously machined component (5) to provide control values (CR,CF,CL) representative of the state of the surface of the machined component. These values are processed using fuzzy logic to obtain output signals ( DELTA V, DELTA Cs,CP) that regulate operating parameters of the machine.  The operating parameters regulated include the speed (V) of advance of the tool (7), the value of the force threshold (Cs) causing stopping of the machining, and the changing of the tool (CP). In grinding the speed of expansion of the abrasive surface of the grinding wheel is used rather than the speed of advance of the tool.
