Title:
ELECTRODISCHARGE MACHINING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2011/151905
Kind Code:
A1
Abstract:
Disclosed is an electrodischarge machining apparatus provided with a machining tank wherein an article being machined is displaced, a machining unit equipped with electrodes which electrodischarge-machine the article being machined, a power supply unit which supplies power between the electrodes and the article being machined, and a control unit (13) which performs drive control of the machining unit and the machining tank in accordance with a machining program. This electrodischarge machining apparatus is further provided with a machining time estimation unit (15) comprising a machining program dividing unit (24) whereby a machining condition column consisting of a plurality of machining conditions that are input are divided into swing-wise machining programs and machining-wise machining programs; a machining data detection unit (21) which detects the number of machining pulses and a machining position, in a machining operation performed under predetermined machining conditions; a machining amount calculation unit (22) which calculates the machined area during swing-wise machining and a machined area during machining-wise machining, on the basis of the number of pulses and the machining position detected by the machining data detection unit (21); and a machining time computing unit (23) whereby machining times under machining conditions subsequent to the predetermined machining conditions are calculated on the basis of the machining condition column and the results of calculations made by the machining amount calculation unit (22).
