Laser scribing with Raycus fiber laser and DIY design Galvo Endurance Lasers – EnduranceLasers

Initial task

Perform scribing with a depth of at least 0.35 mm, so that it is possible to break the material along the scribing cut.

For a rational consumption of the test material, strips ~7 mm wide were cut off from the plate, on which the tests were carried out. All tests were performed at a given laser power of 100%.

The scribing results were viewed using a digital microscope.
