| 20120024821 | WIRE ELECTRIC DISCHARGE MACHINING APPARATUS - A wire electric discharge machining apparatus for machining a workpiece ( | 02-02-2012 |
| 20110240558 | METHOD FOR RECOVERING CORROSION PREVENTIVE AGENT IN ELECTRODISCHARGE MACHINING LIQUID SUPPLY APPARATUS - Disclosed is a method for recovering a corrosion preventive agent in an electrodischarge machining liquid supply apparatus. The method includes the step of passing a first electrodischarge machining liquid having a corrosion preventive agent added there to through, an ion exchange resin column to maintain a suitable specific resistance of the first liquid, and the step of passing a second liquid free from a corrosion preventive agent through the ion exchange resin column to desorb the corrosion preventive agent adsorbed in the ion exchange resin column. The second liquid is, for example, tap water or a machining liquid having a low corrosion preventive agent concentration. The corrosion preventive agent is, for example, adenine which is a purine base. | 10-06-2011 |

| 20100213176 | SINKER ELECTRIC DISCHARGE MACHINING METHOD, AND SINKER ELECTRIC DISCHARGE MACHINING APPARATUS - A sinker electric discharge machining apparatus for machining a workpiece by generating electric discharge in a work gap by applying a voltage having an OFF time, may include a discriminator for generating a first signal representing an abnormal state of the work gap, and a second signal representing a normal state of the work gap; and a pulse controller, in which a first extension factor and a second extension factor that is smaller than the first extension factor are set and a first reduction factor and a second reduction factor that is smaller than the first reduction factor are set. The pulse controller extends the OFF time using either the first or the second extension factor if the first signal is received. The pulse controller reduces the OFF time using either the first or the second reduction factor if the second signal is received. | 08-26-2010 |
| 20100090708 | ELECTRIC DISCHARGE DETECTION METHOD AND ELECTRIC DISCHARGE MACHINING APPARATUS - An electric discharge machining apparatus having a gate signal generator for generating a gate signal, a power source for applying a voltage across a work gap formed between a tool electrode and a workpiece, a gap voltage detector for detecting a gap voltage of the work gap, an electric discharge detector for supplying an electric discharge detection signal representing electric discharge to the gate signal generator. The electric discharge detector includes a counter for generating a sample clock having a frequency greater than the frequency of the gate signal, and a comparator for receiving the gap voltage and determining that a fall in the gap voltage is larger than a specified voltage difference in each sample clock. The electric discharge detection signal is generated in response to an output signal of the comparator. | 04-15-2010 |
| 20090133245 | ENHANCED CORELESS ALTERNATING CURRENT LINEAR MOTOR AND METHOD OF PRODUCING THE SAME - A coreless AC linear motor, including a magnet assembly forming a magnetic gap, and a can, the can further including a coil housing section forming a deep groove. The motor also includes a plurality of coreless coils inserted into the deep groove and arranged in a straight line inside the magnetic gap, and a cover body for sealing the can. | 05-28-2009 |
| 20090112341 | CONTROL DATA CREATION DEVICE FOR MACHINING, AND PROGRAM THEREFOR - An NC data creation device for creating NC data for forming at least one shape by electric discharge machining using at least two blades formed on one or more tool electrodes. Blade registration means registers the at least two blades (Q). Step registration means registers at least two steps to form the at least one shape (P). Blade assignment means assigns the at least two blades to the at least two steps. NC data creation means creates NC data including the at least two steps. The NC data creation means may create position commands for causing movement of the tool electrodes between two consecutive steps. | 04-30-2009 |
| 20090065483 | WIRE ELECTRIC DISCHARGE MACHINING METHOD - A wire electric discharge machining method for cutting a workpiece while moving a wire electrode, supported between upper and lower wire guides substantially perpendicular to a horizontal program plane, along a program path (PQ) having a start point (P) and an end point (Q) on the program plane. The method of the present invention includes a step of varying a taper angle command (θ) within the program path; a step of acquiring a set allowable error (ε); a step of obtaining one or more dividing points (D | 03-12-2009 |
