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. Post-processing of the multi-axis laser strength machine was analyzed theoretically and verified experimentally by using UG NX post-processing editing tool. The results show that positioning accuracy of the machine is less than 0.05mm after compensation, repetition positioning accuracy is 0.02mm. Laser strengthening treatment achieves successfully by using UG NX post-processing editor on machine tool. Experimental results show the feasibility and versatility of a multi-axis laser machine and post-processing. It is helpful for the upgrade from ordinary machine tool to laser processing equipment.
