DATA COLLECTION SYSTEM FOR ELECTRIC DISCHARGE MACHINES
First Claim
1. A data collection system for electric discharge machines, wherein a computer is connected with electric discharge machines over a data transmission path, information on machining conditions of an electric discharge machine is stored in a storage unit of the electric discharge machine, and information sent from the electric discharge machine after completion of machining is collected by the computer,the electric discharge machine includinga detection unit that detects a physical quantity relating to machining conditions during machining either at predetermined intervals or each time a moving part of the electric discharge machine has traveled a predetermined distance,a determination unit that determines whether the physical quantity detected by the detection unit exceeds a predetermined threshold or not,a storage unit that stores the physical quantity or information indicating the fact that the physical quantity exceeds the threshold when the determination unit determines that the detected physical quantity exceeds the predefined threshold, anda transmission unit that sends the physical quantity or the information indicating the fact that the physical quantity exceeds the threshold, stored in the storage unit, after the machining by the electric discharge machine, andthe computer includinga reception unit that receives the physical quantity or the information indicating the fact that the physical quantity exceeds the threshold sent from the transmission unit after the machining by the electric discharge machine, anda storage unit that stores the physical quantity or the information indicating the fact that the physical quantity exceeds the threshold, received by the reception unit.

Abstract
In a data collection system for electric discharge machines, multiple electric discharge machines are connected with a computer over a data transmission path. Information on machining conditions of an electric discharge machine is stored in a storage unit of the electric discharge machine, and information sent from the electric discharge machine after completion of machining is collected by the computer. By minimizing monitoring information that is temporarily stored in the storage unit, various kinds of monitoring information can be stored without being affected by a network environment.
