The same crank pin
on the same crank shaft was measured about 60 times over a period of two weeks at a major automobile engine plant, using the same shopfloor gage.
Finally, using turn-broaching, all the inserts needed for complete machining, roughing, semifinishing, undercutting, and finishing for one crank pin can be put in the tool in one setup.
The major advantage of turn-broaching is that the tool (broach) provides both roughing inserts for high metal removal rates and finishing/undercutting inserts to permit complete machining of crank pins or crankshaft main bearings in one operation.

Therefore, kinetic energy does not go through piston pins or crank pins
The crank pins
on both engines failed almost simultaneously, and the great 800-ton Arkansas drifted helplessly to the shore.
Cams and journals, or main journals and crank pins
of crankshafts, can be done in one setup.
