Laser cutting and laser micromachining are non-contact processes which utilize a laser for micro drilling, micro milling, micromachining, micro patterning, micro scribing and ablation for industrial applications. The cut and feature edges are of high quality with little no burring, low surface roughness and dimensional accuracy.
The laser micro cutting process works by directing the laser beam through a co-axial gas nozzle to the workpiece. The laser melts a thin filament of material according to power and part conduction, the pressure of the coaxial assist gas then removes this molten filament through the underside of the cut. This process is repeated as the laser moves across the workpiece. According to cut conditions the periodic removal of material can sometimes be seen as “striation” lines running from the top to the bottom of the cut edge. This is a single pass processing technique that can create single sided features and asymmetrical features with very small internal radii.
The Laser micromachining process is a multi pass process that removes small layers and volume of the material on each pass. Typically the laser is moved at high speeds over the stationary part, going over the cut path many times to achieve the feature. This is analogous with any machining operation in general, however the layer thickness removed can be in the microns and tenths of thousandths of an inch providing very high dimensional accuracy. For ultrafast or ultra short pulse lasers, almost any material can be processed, particularly plastics and polymers, which are difficult to machine accurately when feature and part size dimensions are small.
Both the laser selected and the design of the system to enable to the laser to provide the necessary process are critical for a production machine.
