I've received some pages relating to Helical Motion, so I can relate what I've learned so far.
In a general sense, helical motion is used to correct for lameness in tooth bearing. Lameness is the affect of tooth bearing concentrated at top of tooth flank and at bottom of opposite flank.
Thus, Helical Motion effect is likened to a proportional adjustment of machine settings that corrects for specific defects in tooth contact pattern. Using helical motion, as pointed out in the method, may be useful in more closely matching a sample gear or pinion.
For those who have machines with helical motion (recognized by four H/M change gears) maybe I could see a show of hands.
