Abstract

824,001. Cutting by electro-erosion. VYZKUMNY USTAV PRE MECHANIZACIU A AUTOMATIZACIU. Dec. 17, 1956 [Dec. 16, 1955], No. 38420/56. Class 83 (4). [Also in Group XXXVIII] Apparatus for profiling a workpiece by electro-erosion comprises a wire saw 15 connected to an electric current source 5 for eroding the workpiece 2; a workpiece support 1 attached to a desk 10 for receiving a drawing of the outline to be cut, and an electro-optical device 13 for scanning the drawing and transmitting the received impulses to a device 14 controlling the relative movement between the saw and workpiece. The wire saw is supported on rollers 6-9. The drawing is illuminated by a light source 11 and the outline on the drawing is projected by an optical system 12 to an electro-optical device 13 such as a photoelectric cell which sends electrical impulses to device 14 controlling the movement of compound slides 3, 4. The speed of movement of the slides and the pressure between the saw and workpiece are also controlled automatically in dependence upon the current in the spark gap.
