This paper studies a laser melting deposition path generation strategy based on industrial robots to addressthe repair problem of aero-engine TC17 high-pressure compressor blades after service damage. This method can analyze the blade damage area with model Boolean operations and embeds a secondary development plug-in in the RobotStudio offline programming software to generate Zigzag-axial

centerline-offset

and edge-helical scanning paths. The path simulation and deposition topography analysis show that when the scanning speed is 5 mm/s

the deposition layer thickness is 0.3 mm

and the overlap ratio is 50%

the centerline-offset scanning path can maintain the speed stable for 95.97% of time

and the speed decline of turning point is tinier. Simultaneously

the formed height after deposition is close to 0.3 mm

and the height fluctuation variance is relatively small with excellent flatness. Furthermore

simulations and experiments on rectangular flat-plate regions show that a continuous path

such as Zigzag scanning path

can dramatically reduce residual stress on the formed surface.
