Two-Cut Vs. Five-Cut Ring & Pinion Sets
Two-Cut And Five-Cut are machining processes that result in different patterns for set-up as seen below.
Tooth height is measured from the root (bottom of tooth) to the crown (top of tooth).
The two-cut tooth is the same height at the toe (inside of gear) as it is at the heel (outside of gear). The two- cut gear set has a natural "bias" condition; that is, the pattern shows up slanted when the pattern is rolled with gear marking compound.
The five-cut tooth height is shorter at the toe (inside of gear) and is taller at the heel (outside of gear). The five-cut gear set appears as a square pattern when the set is rolled with gear marking compound.
