摘要： A wire electrical discharge machine which performs electrical discharge machining on a workpiece, includes: a worktable on which the workpiece is placed; a placement area detector that divides the top surface of the worktable into multiple areas and detects the areas where the workpiece is placed; a placement time measuring unit that measures placement time for which the workpiece is placed on each of the areas detected by the placement area detector; and a cumulative time storage that adds up the placement times measured by the placement time measuring unit for each of the areas as a cumulative time for the area.

摘要： A wire electric discharge machine, configured to determine whether or not electrical discharge machining of a workpiece can be performed, includes a determination unit for determining that wire electrical discharge machining of the workpiece can be performed when a wire electrode is moved toward the workpiece and a contact detection unit detects contact, and for determining that the wire electrical discharge machining of the workpiece cannot be performed when a breaking detection unit detects the breaking of the wire electrode before the contact detection unit detects the contact.

摘要： A controller for a wire electrical discharge machine that machines a workpiece along a machining path by relatively moving the workpiece and a wire electrode to each other while generating electric discharge across an electrode gap between the workpiece and the wire electrode, includes: a machining surface state acquisition unit configured to acquire the state of a machining surface of the workpiece; and a machining path setting unit configured to specify an excessively machined portion of the workpiece based on the acquired state of the machining surface and set an approach point at which the wire electrode is made to approach the machining surface from a machining start point, so as to avoid the excessively machined portion.

摘要： A control device includes a speed setting unit configured to set a relative movement speed of a wire electrode with respect to a workpiece depending on the average of gap voltage per unit time, i.e., average gap voltage, and set the relative movement speed so as to move the wire electrode backward when the average gap voltage is less than a threshold, and a map compensation unit configured to change the threshold from a first threshold that is set when the amount of change in the average gap voltage is lower than a predetermined variation, to a second threshold that is greater than the first threshold, when the average gap voltage has changed in a decreasing direction and the amount of change in the average gap voltage becomes equal to or greater than the predetermined variation.

摘要： A wire electric discharge machine has a function of estimating the time for replacement of a filter based on a use situation for the machine. A time Tr during which the filter is serviceable is calculated according to an equation, Tr=|(Pd−Pn)/ΔP|, based on a fluid pressure variation amount ΔP, a current filter fluid pressure Pn, and a filter life pressure. A remaining available time Td for the filter which takes into account the operation rate of the machine is calculated according to an equation, Td=Tr/W.

摘要： One arbitrary point on an upper surface of a workpiece and two points at arbitrary heights on a tapered section of the workpiece are measured using a contact detector disposed on an upper wire guide of a wire electric discharge machine to calculate the shape accuracy and tapered angle. Based on the calculated data, the upper and lower wire guide support positions of the upper and lower wire guides are calculated. Using the calculated upper and lower wire guide support positions, electric discharge machining is performed on the workpiece.
