Abstract
Dr. Scott Smith, University of North Carolina at Charlotte, US, shares his views on some of the problems encountered by NC verification software to calculate acceleration and machining time in HSM. The verification software miscalculates machining time in HSM, as it fails to account for acceleration and deceleration. Neglecting acceleration and deceleration produces a machining time estimate of 0.150 seconds. This is the main challenge faced when basing a cost estimate using machining time estimated in verification software. The time estimation problem deteriorates, as acceleration continues to be limited and as the average moves become shorter and the programmed feed becomes higher. Increase in acceleration can ensure that the machine operates at full feed most of the time. There are essentially two options to increase acceleration, such as increasing the power of the drive or decreasing the mass that has to be accelerated.
