Computer controlled cutting¶
What is kerf? (Answer from Rico)
- the laser beam of a lasercutter has a width. It is not infinitely thin (it is pretty thin)
- the width of the cut material burned away by the laser beam…equal to the width of the laser beam…is called the kerf
- if you want to cut a slot in cardboard for Parametric press fit…where the parts fit snuggly with one another…you cannot just simply use the thickness of the material as the slot width
- you must subtract the kerf (laser beam diameter width) from the thickness dimension
- if the kerf is 0.5mm (this is too big…used for illustration purpose only)…and the thickness of the material is 5mm…you need to draw up a slot with in your CAD software that is 4.5mm (5mm -0.5mm) to ensure a perfect press fit
- said another way…if you had used 5mm as the drawn dimension…the resulting cut width in the material will be 5.5mm…since the laser beam width will burn away extra material
