Changing Direction Parallel Scan Path Generating Method through Matching Scan Space for Metal Laser Deposition Shaping

Those ultimate reasons of over-cladding and under-cladding are indicated through analyzing between the existing parallel scan mode and the characteristic of metal laser deposition shaping. A kind of scan path generating method is presented, firstly, scan path is generated base on grouping internal parallel filling scan according to the set scan space in the same layer, then, scan direction is changed base on matching different scan space in different layer. Practical application shows that the scan path can effectively enhance the flatness of shaping layer and the fabrication quality, ensure to shape successfully.
