An electrical discharge machine having a concentration detection function for a rust inhibitor containing an organic compound uses coloring of a metal complex produced through the eraction of the rust inhibitor (active ingredient: organic compound) with a color reagent (transition metal ion) to enable a detector to detect the change of characteristics involved in the change of the color of the metal complex. A predetermined amount of working fluid is sampled in a sampling cell at regular time intervals, a predetermined amount of color reagent is added to the working fluid, and the change of the color of the working fluid is detected by the detector. If the concentration of the rust inhibitor is lower than a certain value, the color of the working fluid lightens, the change of the color is detected by the detector, and a command to add the rust inhibitor is issued to a controller. If the concentration of the rust inhibitor is higher than the certain value, in contrast, the color of the working fluid deepens, the change of the color is detected by the detector, and a command to add the working fluid is issued to the controller.

A wire electrical discharge machine for detecting an end face of an object, configured so that when a contact detection movement is started and if contact between the wire electrode and the workpiece is detected, positions in which the contact between the wire electrode and the workpiece is detected are stored as contact detection positions and that when a non-contact detection movement is then started and if non-contact between the wire electrode and the workpiece is detected, positions in which the non-contact between the wire electrode and the workpiece is detected are stored as non-contact detection positions. When it is determined whether or not a set number of times of execution is reached and if the set number of times of execution is reached, a reference position is obtained by adding the radius of the wire electrode and a clearance of the wire guide to an end face determination position.

The present invention provides a wire electric discharge machine including an automatic connection function that enables automatic connection to be securely performed even when no person is present in the surroundings of the machine (with no manual operation). The wire electric discharge machine performs automatic setting procedure of a connection condition and determines whether it is the time point stored in a computer numerical control (CNC) device. When it is the time point stored (YES), an automatic connection condition 2 is read. When it is not the time point stored (NO), an automatic connection condition 1 is read. The wire electric discharge machine then performs disconnection procedure and connection procedure to complete the process.
