Feed rate calculation algorithm for the homogeneous material deposition of blisk blades by 5-axis laser cladding

The application of laser cladding technology is becoming widely extended in the industrial environment due to its advantages of high added value and direct manufacturing or repair of complex parts. These complex parts require 5-axis laser cladding deposition processes whose programming demands optimized and continuous tool paths. The present work develops a programming methodology for a homogeneous material deposition of a continuous 5-axis laser cladding process applied to rapid manufacturing of blisk blades. Initially, the blisk blade geometry is defined and the process requirements are studied considering key factors such as the best parameters, nozzle trajectories, and feed values. Therefore, the proposed algorithm solution for feed variation control is applied to the process obtaining a more homogeneous structure. Finally, a blisk case study is developed according to the proposed solutions.
