IPC: G06F13/00
Filed: 1989-09-28
Abstract: PURPOSE:To reduce the system overhead by requesting the updating of a copy via a data control means after the latest expected time. CONSTITUTION:When the data needed by slave computers 2 and 3 have the deviation or at the access time when the update time are periodical, e.g., at the end of each month, year, etc., only the data necessary for computers 2 and 3 are recorded to the computers 2 and 3 and used repetitively.

Title: Wire-cut electric discharge machine
Inventor: MAGARA TAKUJI
IPC: B23H7/02
Filed: 1986-10-24
Abstract: PURPOSE:To improve machining precision on a corner part, by providing a control means which predicts a change in a machining amount at a corner part and corrects a gap between the sides of electrodes produced along with a change in a machining amount. CONSTITUTION:In a finish machining, a discriminator 12 discriminates whether a present machining position is under circular movement of a corner part, and when under circular movement of the corner part, a signal by means of which a control device 13 is motioned is transmitted. By means of a signal inputted from the discriminator 12, the control 13 selects a new interpole servo reference voltage for machining a preset corner part. The interpole servo reference voltage is switched, and upon completion of machining of a corner part, a reference voltage is restored to its original value. For example, since, in the case of machining of an incorner, with the increase in a machining amount, a gap between the sides of electrodes is increased to cause overcut, the control device 13 switches the interpole servo reference voltage to a high value so that the gap between the sides of electrodes is decreased so as to correct overcut by a machining integration effect.
