LMD Inconel 718 Spiral 2020-07-31 left

Description of dataset 10.5281/zenodo.4061502 Deposition of Inconel 718 square spiral with process parameters: - Nominal power = 300 (W) - Nominal velocity = 600 (mm/min) - Powder flux = 0.0825 (g/s) - Spiral size: 60 mm side, 3 mm step - Nr. nozzles = 4 - Argon carrier flux = 4 (l/min) - Argon shielding gas flux = 15 (l/min) - Substrate temperature = Ambient This experiment took place on the same substrate of 10.5281/zenodo.4049842 (on the "left") and follows the same part program. In this case, the laser spot is slightly off-center in camera images. The dataset is constituted by: - Melt pool images, in file Deposition_2020_07_31__13_09_50.zip, acquired at 200fps with 850 nm narrow band filter, 1ms exposure time. 400x400 px size - trackData_20200731_left.csv containing: - t: timestamp in ms. Synchronized with imData_20200731_left.csv - Xpos: laser spot X position in workspace - Ypos: laser spot Y position in workspace - Zpos: laser spot Z position in workspace - G1: binary signal indicating active deposition (G1=1) or not - D: track width measured at [Xpos(t), Ypos(t), Zpos(t)] - H: track heigth measured at [Xpos(t), Ypos(t), Zpos(t)] - A: track section area measured at [Xpos(t), Ypos(t), Zpos(t)] - sdres: roughness index of section profile (std. deviation w.r.t. smoothed profile) - Vnom: laser spot translational speed in m/s (computed from Xpos, Ypos, Zpos and t data) - Pnom: nominal power - V: Vnom in mm/min - imData_20200731_left.csv containing: - t: timestamp in ms. Synchronized with trackData_20191205_left.csv (some frames may have been lost) - I_mean: mean image intensity (only on red channel) - I_mean_crop: mean image intensity computed on central cropped image area (180x180 pixels) - M_I_mean: I_mean after application of 8-sample moving average - M_I_mean_crop: I_mean_crop after application of 8-sample moving average - fileName: associated image file name - beamON: laserON signal obtained from thresholding on images (background noise = off, minimal intensity level = on)
