Wire electric discharge machine

Abstract

The invention provides a wire electric discharge machine which prevents occurrence of failure beforehand and prevents machining stop. This can be effected by acquiring an image of a part using an image information collection unit such as a visual sensor with respect to matters, which requires inspection management of the amount of a wire accumulated in a wire electrode storage box, a remaining amount of a wire of a wire bobbin, a level of a machining liquid of a water reservoir and the like, and issuing warning when it is determined, based on the obtained image information, that the failure is highly likely to occur as the wire deposition amount is close to a limit of the wire electrode storage box, the wire remaining amount is small, or the machining liquid level falls below a set value to deal with the state based on this warning.

Description

technical field [0001] The present invention relates to a wire electric discharge machine, and more particularly to a wire electric discharge machine which is easy to perform maintenance and inspection. Background technique [0002] Compared with ordinary machine tools, the number of parts and consumables of a wire electric discharge machine is very large, so there are many places for daily inspection, and the burden on the workers who perform inspection management is heavy. [0003] On the other hand, as the electrical discharge machining progresses, the state changes, and if the inspection and management of items requiring management corresponding to the changes are neglected, the performance of the machine cannot be fully exerted and problems may arise in the machine. For example, as a phenomenon caused by neglect of inspection and management, there are cases such as the following, that is, [0004] If you forget to discard the used thread, the accumulation of thread in ...

[0009] Loss of time during process interruptions;

[0010] The processing of wire electric discharge machine generally performs rough machining and finishing machining of cutting out the shape from the workpiece. The finishing machining improves the accuracy of the shape and the surface roughness by discharging while passing through the path formed by the rough machining. , especially in the case of finish machining, once machining is stopped during machining, it becomes the cause of wrinkles on the machined surface due to redischarge at the same position when machining resumes;
