Abstract

1321131 Gear shaping; cutting gears; sharpening cutters REGIE NATIONALE DES USINES RENAULT 15 June 1970 [16 June 1969] 26448/70 Headings B3D B3K and B3L A method of cutting gear teeth on a workpiece 7 Fig. 1, using a pinion tool 6, comprises the steps of calculating for a theoretical pinion tool 3 for each of a plurality of different states of sharpening, a theoretical profile for the tool, using the profile of the workpiece to be obtained and its basic rack, calculating from the theoretical profiles a theoretical hob 4, which would be capable of generating the tool, manufacturing from the theoretical hob a so-called simplified hob 5, milling the so-called simplified pinion tool 6 using the simplified hob, sharpening the leading face of the simplified pinion tool, cutting gear teeth on the workpiece 7 using the simplified pinion tool, comparing the profile of the teeth cut on the workpiece with the desired profile, and if necessary correcting the simplified hob profile to give in turn a corrected simplified pinion tool profile, and hence a corrected workpiece profile. Pinion tool 6 is machined by hob 5 Fig. 6, the hob being rotated at the speed W3, vertically movable in the direction 21, and fed in direction T3, and tool supporting table 19 is fed in the direction P, and is rotated. Pinion tool 6 is sharpened by a grinding wheel 42 Fig. 13.
