[0002] With the continuous development of laser technology, the current fiber laser cutting machine has gradually replaced the gas laser cutting machine. The laser cutting machine has the characteristics of high precision, fast cutting speed, no restrictions on cutting patterns, automatic typesetting to save materials, smooth incisions and low processing costs.
