Assessment a cut of quality of sheet materials in the conditions of high-precision plasma cutting
The studies of assessment a cut of quality of sheet structural materials in terms of surface roughness after plasma cutting conducted are conducted. Sheet structural steel Ст 3 with thickness of 3…20 mm on the assumption of its guaranteed punching and further plasma cutting by HiFocus; HiFocusplus; HiFocus F is chosen. The values of processed surface roughness for cutting technologies studied for different thicknesses are specified. A comparative evaluation of the surface roughness for selected technologies is conducted. The presence of surface waviness when using cutting technology HiFocus F is revealed, high altitude and stepper waviness characteristics are defined. Recommendations on the use of high-precision plasma cutting technology, depending on the desired thickness and roughness of processed surface are given.
