Setup Strategy
5-axis cutting keeps the peg datum in one frame
Footrest components are awkward parts. The mounting boss, pivot bore, grip face and heel-guard plane rarely sit on three orthogonal axes. On a 3-axis machine you re-fixture four or five times, and each re-clamp adds stack-up error at the pivot.
We run these on 16 simultaneous 5-axis machining centers. The peg body, spline or flat, and the mounting interface are cut in one or two setups off a single datum. That is how the pivot bore and the grip face stay perpendicular to each other instead of drifting apart.
