CNC machine tool which conducts maching to a desired shapethrough control of each axis is a kind of position control system and recognized as aservo mechanism of top priority. In machine tool control there is another schemereferred to cutting force control. It is a scheme to maximize feedrate in a certainallowable range for productivity improvement by letting the actual force follow thedesired cutting force determined in advance according to tool and workpiece material tobe used. When conducting shape machining only by an independent position control ofeach axis inevitably there would occur contour error(shape error) mainly due todynamic characteristic mismatch of axis driving mechanism. Contour error control is ascheme to minimize such an error. Presently since those three control strategies havebeen studied separately and an integrated scheme has not been established to realize the3 strategies simultaneously both the cutting force control and the coutouring controlhave not attracted a serious attention rela |
