Gears are generally made by the cutting machines like Micron-Hobbing machine or Fellows-Gearshaper. But in this research the author attempted, as an lnnovation, to make small gear-wheels by the generating method, using dice. The size of gears, e.i. spur and helical gears, is D.P.30-D.P.12. Mildsteel is the chief material, but some Al-alloy and Cu-alloy are also used. For the installation a lathe is reconstructed, and two tool rests are attached to it. When the gear-shaped dice on the rests push and rotate the gear blank, the desired gears are generated. Their accuracy of eccentricity is 1/1000 anb that of circular pitch 3/1000.
