Inspect lubrication, tools, mechanics, e.g. oil level, lubricating
film, blunt or damaged tools, guideways, ballscrew.
Inspect coupling system. e.g. belt tension, gear unit, coupling.
Ensure sufficient lubrication,
replace faulty tools, correct
mechanical errors.
Check hydraulics, pneumatics, brakes for e.g. weight balance,
Hirth coupling, motor braking
Sequence for finding errors in the control loop
