What extra stock a later bend or mill still needs on the blank
A flat blank is not the finished size. Add bend or mill stock before nesting. The kerf already gone does not pay for the next pass.
Editorial Team
The SliceKey desk writes independent notes on kerf, nesting, and the cost of wasted stock. It does not inspect a shop floor or write a quote.
What kerf compensation changes on the toolpath
Kerf compensation offsets the toolpath so the slot sits in the waste. The drawing stays unchanged. Check the first part with a caliper.
What a Speed, Power, or Pressure Figure Has to State Before It Is Usable
A speed, wattage, or jet pressure is usable only with material, thickness, and machine named beside it. Treat a catalog figure as a start.
How to read a blade, nozzle, or lens listing for kerf
The width printed on a blade, nozzle, or lens listing is the maker’s figure for that part. Measure the slot in your sheet after any consumable change.
Why Fabric, Foam, and Label Stock Leave a Different Waste Shape Than Sheet Metal
Fabric, foam, and labels waste stock in a different shape than sheet metal. Count nap, stretch, print repeat, and crush before the nest.
Why Thickness Changes the Cut Even When the Material Name Stays the Same
A thicker sheet gives the blade, beam, or jet more distance to wander, taper, or heat. Measure a coupon at this thickness before you reuse an old kerf.
How an Offcut Differs From Scrap on a Repeat Job
An offcut still fits another part of the same stock. A strip too narrow to nest is scrap. Measure the leftover before the next job.
What a Kerf Width Is Actually Measuring
Kerf width is the slot a saw, laser, plasma, or waterjet removes, not the finished part. Measure that slot on a test cut before the batch.
Cut a Test Coupon Before a Kerf Number Goes on a Batch
Measure a test coupon in the same material, thickness, and machine as the job before a kerf number is used on a batch.
What changes when the stock is a coil or a roll instead of a sheet
A coil or a roll loses edge trim and a tail, not a sheet skeleton. Count parent width, slit width, and leftover length before the quote.
