摘要：Laser cutting characteristics including power level and focal length are investigated in order to obtain surfaceroughness with maximum cutting speed. The surface roughness is investigated for a laser power range of 1000–1500Wand focal length 122-132, gas pressure 7 bar constant for brass materials.This paper is studied the effect of focal lengthon surface roughness 1 mm thin brass sheet using an oxygen as assist gas. The cutting cross section was measuredsurface roughness. The variation was analyzed with laser power and focal length. We use here plasma detector sensorfor predetermined cutting speed. The full factorial method is used for cutting speed and surface roughness.
