Abstract: A method of manufacturing an engine connecting rod includes mounting a rod on a first mount configured to rotate, mounting a cap on a second mount configured to rotate, positioning a spindle head such that a tool of the spindle head contacts a first connecting end of the rod, machining the first connecting end by spinning the first mount, machining the first connecting end by moving the spindle head, positioning the spindle head such that the tool of the spindle head contacts a second connecting end of the cap configured to be coupled to the first connecting end, machining the second connecting end by spinning the second mount, and machining the second connecting end by moving the spindle head. The spindle head is moveable in a first direction extending between the first and second mounts, a second direction perpendicular to the first direction, a third direction perpendicular to the first and second directions, and rotatable about an axis.
