Hi Javat, 
I don’t think so; the value wouldn’t decrease by like 0.416 rad/sec. You can think of it like this: if someone starts running at a constant velocity of 20 m/sec and runs for 0.5 sec, his velocity will remain the same and will not reduce to 10 m/sec without any external force.

As far as I can understand your question, the drill is rotating at 416 rad/sec for a cycle time of 0.001 sec.
Are you able to see any results while changing the result from the true scale to the large scale? Will you please check the joint that you have used for rotating the drill? Is the drill free to rotate or not?
