Group work - Computer controlled cutting

Finding the optimum speed for Engraving & Cutting :
In RD works, there three options :cut,scan,pen and dot. The ScAn option RDworks, We drew 10 rectangles and layered them differently with different power but same speed. I did’t get the required result, then we changed the Spedd with same power. Eventually the optimum Power and Speed Combination for Cardboard and 4mm Acrylic was achieved.

Test Cuts on cardboard and acrylic :
Here we have written the optimum speed and power range to be used for cardboard and acrylic. These test tabs are kept at the laser cutter for future reference.

Measuring KERF


For Measuring the KERF we made 10 cuts within a rectangle. After cutting we shifted all the cut rectangle to one side and measured the gap. Divide the gap by 10, the final obtained value is the KERF of the laser cutter we are using, which is in our case is : 0.3mm

Distance after shifting the cuts = 3 mm. Total number of cuts = 10. So 3⁄10 = 0.3mm which is the KERF of the LASER.
