Project Overview

Metform, a division of MacLean-Fogg Component

Solutions, is in the business of machining gear

blanks for use in 8 and 9 speed transmissions.

These gear blanks are produced at a mind-boggling

rate with the assistance of highly precise CNC

machines. However, after multiple inspections, it

was observed that the bore dimension for some

of the gear blanks was extending outside of

the allowable tolerance. The cause of this was

determined to be a product of bore lobing, a

common problem in the machining of thin-walled

parts. Our task was to design improved lathe jaws

that would distribute the clamping load along the

entire surface of the gear blank.
