How much length do four 80 mm pieces and four 2 mm cuts need?
Illustrations generated with OpenArt. Narration uses free local Kokoro neural voices. Illustrations are visual aids; the written lesson carries the explanation.
A saw removes a strip of material. That width is the kerf. It belongs in a cutting plan.
Kerf = material removed
Three 100-millimetre pieces from a long board need three separating cuts if each piece is cut free.
3 pieces · 3 cuts
With a measured 3-millimetre kerf, allow 300 plus 9 millimetres, before any extra trimming allowance.
300 + 3 × 3 = 309 mm
Cut counts depend on the layout and usable factory edges. Measure your blade kerf on a scrap and plan each cut.
