Abstract
This paper proposes a new method for correction of tool run-out on a machine tool using a laser. The laser is irradiated on the tool shank of the attached tool on the machine spindle. The thermal stress caused by laser irradiation at the irradiated part can make a deformation. First, the deformation patterns based on the thermal stress are shown. Second, experiments are carried out in order to investigate the influences of laser irradiation conditions on the deformation. Finally, a few case studies are performed using a cutting tool and succeeded in reducing the run-out to sub-microns.
