WebBecause the critical meander scale depends on the jet speed U, and also because the relation β 0 Y ~ K U depends on the shape of the meander (Y and K are not simply related … WebThe bulk samples were built with different scanning strategies with the aim of reaching a low relative porosity of the material. The combination of the chessboard strategy with a 2 × 2 mm field size fabricated with an out-in spiral order was found to eliminate a …
Influences of the scanning strategy on surface roughness in …
WebThe direction of core meander scanning was rotated by 67° between successive layers. For the cylinders, the border parameters were kept constant with power – 100 W, point distance – 45 μm, and exposure time – 40 μs. 2 1/2 0 1 2 o z rr r λ π =+ (1) Table 1. WebJul 23, 2024 · Meander scans are parallel to one another and occupy a single area. The crack density in an area subjected to a meander scan was lower than that in an island-scanned area. The island scanning strategy was described by Smith et al. to be less effective in achieving high bulk density compared with a fractal scanning strategy that is … crowley fire department crowley tx

WebDec 9, 2024 · However, most researchers have ignored the importance of the scanning strategy. In this study, the Taguchi method was used to investigate the relation between warpage and fundamental parameters (laser power, scanning speed, overlap, and scanning angle) to fabricate stable and undistorted specimens. ...
