Defocused amount and Z-increments affect the accuracy and efficiency of thin-walled part with laser cladding forming.The key to obtain high-accuracy thin-walled part is to make the Zincrements equal the cladding height under initial defocused amount.In order to solve the problem of forming thin-walled part with high accuracy and efficiency,powder density distribution model of laser cladding system with coaxial-powder feeding is established based on the probability theory,the calculation formula of cladding ...
