1. Testing the mill's tram with a Dial test indicator (DTI) is very common, attach it to the spindle of the milling machine and check the tram through the readings of the indicator on two points of the X-axis and that on two points of the Y-axis are the same. If the readings are different, adjust the mill head until they become the same. 2.

gradients in machine casings, but without such instrumentation it is also possible to identify secondary machine problems which can indicate inaccurate shaft alignment. Machine vibration. Machine vibration increases with misalignment. High vibration leads . to fatigue of machine components and consequently to premature machine failure.
Machine runout is a measurement of cutting variation along a tool's cutting surface due to misalignment. Prefect alignment of any rotating machine cannot be achieved, so all mills will have some amount of runout, but it can be minimized by ensuring the cutting tool is concentric with the milling head and aligned in the vertical axis.
