This paper presents an experimental analysis on manufacturing and geometrical characterization of micro-channels fabricated on AISI 316L steel by laser milling. Micro-channels, with rectangular section, were fabricated keeping the process parameters and the number of removed layers constant and varying the width of each channel. The geometry of micro-channels was revealed using a 3D digitizing system Optimet Conoscan 4000, which combines a non-contact, single-point measuring sensor based on conoscopic holography technology with x-y positioning with a resolution equal to 15 microns on the x and y axes. The use of this measurement technology allowed obtaining complete information of the shape geometry and dimensions of built channels.

Abstract
This paper presents an experimental analysis on manufacturing and geometrical characterization of micro-channels fabricated on AISI 316L steel by laser milling. Micro-channels, with rectangular section, were fabricated keeping the process parameters and the number of removed layers constant and varying the width of each channel. The geometry of micro-channels was revealed using a 3D digitizing system Optimet Conoscan 4000, which combines a non-contact, single-point measuring sensor based on conoscopic holography technology with x-y positioning with a resolution equal to 15 microns on the x and y axes. The use of this measurement technology allowed obtaining complete information of the shape geometry and dimensions of built channels.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
