Some experimental studies on plasma cutting quality of low alloy steel

Abstract

This paper presents an experimental study to evaluate the effect of the cutting parameters on the cut quality during plasma cutting of 5 mm thick low alloy steel sheets. The cutting parameters considered include cutting speed and plasma gas pressure. The CNC portal cutting machine VARCUT L2 by plasma device type D12000 is used in the experiments. Results show that good quality cuts can be produced in plasma cutting of low alloy steel, at the cutting speed from 400 to 700 mm/min and at the plasma gas pressure from 4 to 5 bar.
