Laser Cutter testing

This task is to test the Laser cutting as a machine, measuring the kerf, speed and power, to take it in consideration while designing and cutting/ scanning.

What is Kerf?

The laser burns away a portion of material when it cuts through. This is known as the laser kerf and ranges from 0.08 mm – 1 mm depending on the material type and other conditional factors. Although above 0.45 mm is only experienced when cutting thicker foams.

We tested the kerf and we have it at 0.15 ~ 0.2 mm:

POWER and SPEED on deference material:

WOOD

CUT:

Speed = 20 m/s.

Power = 60~65.

SCAN:

Acrylic

We tried to cut acrylic of two thickness 3 mm and 6 mm, the result was that both at speed 5 m/s and power 50 p it cut perfectly, while at speed 8 m/s and the same power it did not cut the 6 mm but cut parts of the 3 mm.
