Abstract
A numerical controlling device and a tooling apparatus having thereof, in which performance required for the machining is greatly improved correspondingly to a degree of importance according to a type of the machining and thus high efficiency and high accuracy in the machining can be obtained, by referring a database based on a type of a specified cutting tool and workpiece, and of a machining mode including an operating path of a movement of the cutting tool and workpiece, and by selecting a control parameter which relates to an adequate operating speed and operating position in the entire operating path during machining and non-machining.
Claims12
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.
A tooling apparatus for performing a predetermined machining to a workpiece on a machining table, comprising:
- a machining table for fixing the workpiece;
- a cutting tool enable to be brought into contact with the workpiece for the machining;
- means for numerically specifying an operating path for operating said cutting tool and/or said machining table;
- a database having a control parameter relating to an operating speed for operating said cutting tool and/or said 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 said 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 performing the predetermined machining by operating said cutting tool and/or said machining table with the operating speed based on the control parameter elected by said selecting means.
