Kerf Offset Calculator
Recommended kerf width and the CAM offset to apply, from conservative published-typical ranges.
Typical kerf width
0 in
Apply in CAM (offset per side)
0 in
offset = kerf ÷ 2
Typical starting points, not guarantees. Kerf varies with consumable condition, standoff height, speed and gas/air quality. Verify with a test cut on your own machine before running parts.
Starting estimate only. Actual speeds depend on your specific machine, consumable condition, and gas/air supply. Values are deliberately conservative — dial in with a test cut, and slow down 15–20% for your first run on a new setup.
Material Weight Estimator
Flat plate / sheet weight from density × volume.
Weight per piece
0 lb
Total weight
0 lb
Densities used: mild steel 0.284, stainless steel 0.286, aluminum 0.098 lb/in³. Formula: W = ρ × t × L × W × qty.
Job Cost Estimator
Per-part cost and a suggested sell price — every step shown.
Material: $ per sheet
Material: $ per lb
Material cost / part
$0.00
Machine cost / part
$0.00
Total cost / part
$0.00
Suggested sell price / part
$0.00
The math
Material / part = sheet cost ÷ parts per sheet or $/lb × weight per part
Machine / part = cut time (min) × (hourly rate ÷ 60)
Total / part = material + machine
Sell price = total × (1 + markup ÷ 100)
Covers material + machine time only. Add consumables, fixturing, finishing, packaging and shipping on top if they apply to your job.
