Abstract:
A numerical controlling device used in a tooling apparatus in order to perform a predetermined machining to a workpiece on a machining table by bringing a cutting tool into contact with the workpiece, comprising:means for numerically specifying an operating path for operating the cutting tool and/or the machining table; a database having a control parameter relating to an operating speed for operating the cutting tool and/or the machining table, said control parameter includes a servo gain and a time constant of adjustable speed; specifying means for specifying a machining mode including types of the cutting tool and/or the workpiece; selecting means for selecting the control parameter based on said database so as to obtain an adequate operating speed in the entire operating path during machining and non-machining according to the specification by said specifying means; and means for outputting a control command to said tooling apparatus so as to operate the cutting tool and/or the machining table with the operating speed based on the control parameter selected by said selecting means.
