4. Computer controlled cutting

For this group assignment, we created two combs to define offset size becuase of kurf of laser cutter.

By fitting these combs each other and comparing printed numbers (sizes of gaps) with actual thickness of cardboards, we could know difference between actual and desired cutting sizes. In our case, thickness of the cardboards was about 2.8mm. And the most appropriate actual size of gap to fit comb rigidly was 2.6 mm.

From the result, we calculated offset that should be considered to use laser cutter we would use.
The offset was (2.8-2.6)/2=0.1(mm)

group assignment:
characterize your lasercutter’s focus, power, speed, rate,
kerf, and joint clearance
