7 Critical Datum and Fixturing Errors That Ruin Gear Blanks after Hobbing — And How to Prevent Them

A gear that fails after hobbing is rarely a problem with the cutting parameters. In most cases the defect is already fixed into the part before the hob ever touches it — through a bad datum, a dirty face, an overloaded clamp, or an unchecked runout. When the tooth rim is wrong, the shop often blames the machine. The machine, more often than not, was only reproducing an error that the setup introduced. This article is written from the other side of the process: instead of a step list, we look at the seven most common mistakes that put a gear blank at risk, the symptoms each one produces, and the checks that stop them before the first pass.
