4. Computer controlled cutting

Assignment

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

individual assignment : cut something on the vinylcutter design, lasercut, and document a parametric construction kit, accounting for the lasercutter kerf, which can be assembled in multiple ways, and for extra credit include elements that aren’t flat

Parametric construction kit

By using FreeCAD

I use Feadi’s tutorial on zoom here and start to create a part with a groove which change with the thickness of the material.

Length of the groove depending on thickness (“épaisseur”) and lasercutter kerf thanks to a mathematical formula.
Extrusion which is the thickness (“épaisseur”) = 1.
Part with thickness = 3 and kerf = 0.2.
Part with thickness = 6 and kerf = 0.2.
