Abstract
This article is devoted to experimental studies of pulsed cutting of B93 aluminum alloy of holes, grooves in combustion chambers and the inlet fairing of a gas turbine engine, which were carried out with the change of the following parameters: laser power, cutting speed, frequency and duration of pulses, deepening of the focal spot into the material. The dependences of the cutting speed, laser radiation power on the cutting width and surface roughness were obtained, the results show an increase in the quality of cutting with the use of compressed air and an increase in the quality of processing.
