Fig. 6: Fingerprint extraction for laser textured superhydrophobic surfaces.
From: Towards next-gen smart manufacturing systems: the explainability revolution
a The experimental setup of the micro-machining system, which consists of micro-milling and nanosecond laser texturing capabilities, is illustrated. b The concept of process and product fingerprints is presented, focusing on three specific correlations. Correlation A is between the process parameters and the end functionality, the contact angle. Correlation B connects the geometric characteristics of the product, such as Sa, Sz, Sku, Sdq, and Rz, with the contact angle. Correlation C links the process parameters with surface features. c Four 3D surface topography images, obtained from an optical profilometer and produced by different process parameter combinations, are shown. The resultant contact angles shown within the topography images are 131°, 141°, 152°, and 161°.
