✦ Synopsis
This paper presents in-time motion adjustment in laser cladding manufacturing process as a means to improve dimensional accuracy and surface ÿnish of the built part. Defects occurring during laser cladding degrade the part quality such as dimensional accuracy and surface ÿnish. In this paper, in-time motion adjustment strategy was presented to remedy and eliminate defects occurring during laser cladding to improve the dimensional accuracy and surface ÿnish. Based on the relationship between the motion of laser head relative to the growing part and other parameters in e ects on clad proÿle, the laser traverse speed, stand-o distance and laser approach orientation to the existing clad layer were adjusted by instructions from a close-loop control system in real time to remedy and eliminate defects. The results of the experiments veriÿed the e ects of in-time motion adjustment on dimensional accuracy and surface ÿnish.
