Abstract
1331672 Electro-erosion A G FUR INDUSTRIELE ELEKTRONIK AGIE LOSONE BEI LOCARNO 24 June 1971 [24 June 1970] 29776/71 Heading B3V [Also in Division G3] An electro-erosion machine arranged for control by a programmed electric system, see Divisions G2-G3, comprises a cross-table 1 displaceable in the y-co-ordinate relative to a base-plate 24 by a stepping motor 11. A unit 12, carrying spools and guides for a wire electrode 36, is displaceable in the X co-ordinate relative to a yoke 13 of the cross-table 1 by a stepping motor 14. A workpiece 33 is clamped in a container 34, for a dielectric liquid, and the wire 36 is lead through guides 31, 32. The guide 31 is mounted on a small cross-table 2 which is displaceable in X, Y and Z co-ordinate directions. In an alternative arrangement, Fig. 2, not shown, each wire guide is mounted on a crosstable and independently positioned The digital control system is responsive to a punched tape and incorporates interpolators for linear, circular or parabolic movement between programmed positions. Facilities are provided for inhibiting the interpolators when a defect, such as a short-circuit, occurs in the operating gap and to initiate a limited reverse motion in response to information stored in separate return memories or memories incorporated in the interpolators.
