摘要: A machining simulation using graphic data is conducted prior to the machining, the frequencies of forced vibration and/or load variation due to intermittent cutting are simulated according to machining information by machining simulation means (17), and a numerical control command is produced with reference to the frequencies obtained by the simulation by a numerical control command producing means (18). The simulation can be reflected on the actual machining and the creation of a machining program under the condition that the spindle rotational speed is suited to the actual machining. Hence the frequencies of forced vibration and/or load variation due to intermittent cutting and their harmonic frequencies are not approximate to the natural frequencies of the machine, tool, jig, and work, and chattering due to resonance is prevented. Therefore the surface precision can be improved.

摘要: A machining simulation is performed on a graphic data basis prior to machining. Machining simulation means (17) simulates a forced-vibration frequency and/or a load variation frequency occurring due to interrupted cutting on the basis of machining information, and numerical control command generating means (18) generates a numerical control command on the basis of the frequencies obtained from the machining simulation means (17). A spindle rotation speed can be reflected on the actual machining and the generation of a machining program under conditions optimum for the actual machining. Therefore, the interrupted-cutting forced-vibration frequency and/or load variation frequency, or harmonic frequencies thereof which are integral multiples thereof are prevented from being close to the natural frequency of a machine, a tool, a jig or a workpiece. Thus, chattering due to resonance can be prevented, thereby improving a surface accuracy.
