    Question Setting the right kerf value?

    Hello,

    I am going to have my first tabbed box cut. It will be made of 6mm birch plywood.

    I don't know which kerf value to encode in the box designer (Tabbed Box Maker for Inkscape). I suppose it's better to choose a value which would be a bit too small rather than too big?

    Currently I have set it 0.22mm according to some website whereas the shop where I plan to have the cutting done tell me to set it to 0.3mm. What's the more conservative choice to be sure that the parts can be interlocked? Should I even set it to a lower figure?

    Thank you for helping.

    You should design a square - something simple like 1" x 1" or if you are working in metric - 25mm x 25mm. Have the shop cut it for you out of the material you are using, and measure the difference with a caliper.

    Kerf values are machine specific. Different lense sizes & quality…
    Even two duplicate lasers can give you different values. The only way to be sure of the fit is to run test parts & change the values as needed. This is basic so I'm assuming that whomever you are jobbing this out to has no knowledge of what they are doing.
