摘要
06Cr19Ni10不锈钢是一种普遍使用的材料,常被应用于军工产品、仪表器械以及各种机械设备中。试验利用光纤激光切割加工2 mm厚06Cr19Ni10不锈钢板材,通过将激光功率分别设定为300 W、400 W、500 W,切割速度分别设定为1.5 m/min、2.5 m/min和离焦量设定为0 mm、-1.5 mm、-2.5 mm,进行切割尺寸为30 mm×120 mm试样件来确定激光功率、激光切割速度、离焦量等对零件加工精度及表面质量的影响规律,最终得出当激光功率设定为400 W、切割速度1.5 m/min、离焦量-1.5 mm时,能有效地确保光纤激光切割06Cr19Ni10不锈钢的零件质量。
06Cr19Ni10 stainless steel is widely used in military products,instruments and various mechanical equipment.Here,the fiber laser was used to cut 2 mm thick 06Cr19Ni10 stainless steel.By setting laser power to 300 W,400 W,500 W,cutting speed to 1.5 m/min,2.5 m/min and defocusing amount to 0 mm,-1.5 mm,-2.5 mm respectively,the specimens with a size of 30 mm×120 mm were cut to determine the influence of laser power,laser cutting speed and defocusing on the machining accuracy and surface quality of the parts.Finally,when the laser power is set to 400 W,the cutting speed is 1.5 m/min,and the defocusing amount is-1.5 mm,the quality of the part of the fiber laser cutting 06Cr19Ni10 stainless steel can be effectively ensured.
