摘　　要：为满足模具行业对激光强化设备的需求,研制了一台多轴激光强化机床。在普通三轴数控机床基体的基础上,对原机床主轴部位进行改进,加入两个旋转轴、激光器及CCD观察系统。采用激光干涉仪对机床运动轴的定位精度和重复定位精度进行测量和补偿,分析机床各运动轴的运动和激光加工的特点,结合UG NX后处理编辑工具对多轴激光强化机床的后处理进行了理论分析和实验验证。结果表明,补偿后机床的定位精度不大于0.05mm,重复定位精度为±0.02mm。根据现有模具,运用研制的UG NX后处理进行编程,导入到机床中,实现了激光表面强化处理。这一结果证明了试验激光加工机床及后处理的可行性,对普通机床升级到激光加工设备是有帮助的。To meet requirements of laser strengthened machines for mould industry , a multi-axis laser machine was constructed .On the basis of ordinary three-axis computer numerical control machine tools , spindle part of the ordinary machine was improved by adding two rotary axes , a laser and a CCD observation system .Positioning accuracy and repeatable positioning accuracy of the machine motion axis was measured and compensated by a laser interferometer .Motion features of the machine and characteristics of laser processing were analyzed .
