US 6,298,279 B1 · CAD/CAM apparatus and machining apparatus for processing position/force information

Abstract

A modeling operation of a shape of a work (3) is performed by a CAD (1). A tool path calculation section (15) calculates path data having, as an attribute, position and force information by a fuzzy inference or the like by shape information, machining information and machined surface information. A machining program is produced on the basis of the path data in a machining program producing section (17). Orbit data for every renewal cycle Tm concerning the position, posture, force and moment are calculated in a position and/or force operation planning section (19) and a position and/or force orbit producing section (21). Then, a simultaneous feedback control is performed for the position and the frictional force in a controlling section (23).
