“…However, at higher levels of heat supply, the higher temperature gradient may result in more molten material [26] and, as a result, the removal of the molten material from the cutting zone, thereby affecting the surface quality. Increasing cutting speed resulted in lower values of SR, which can mainly be attributed to the shorter exposure periods of the laser beam on the specimen [10,42]. An increase in SR was observed with increasing values of gas pressure.…”

“…An increase in SR was observed with increasing values of gas pressure. Increasing gas pressure generated more peaks and valleys in the cutting region, which in turn led to increased values of SR [42].…”
