It features a considerable variation of the cutting forces and torque which occur due to fluctuations in the processed material hardness, chip accumulation in the instrument chip grooves, unsymmetrical sharpening of the cutting edges.
The effect on the characteristics of drilling dynamics of the cutting force can be considered as a function of the processed material hardness and cutting layer thickness.

It could be caused by both degradation of materials properties and TLM measurement error caused, for example, by changes in the active epilayer thickness under the contacts caused by Ni silicide formation.
