Try the starting example
- Desired physical tab width (mm)
- 10
- Desired physical slot width (mm)
- 10
- Measured total kerf width (mm)
- 0.2
- Extra physical clearance at slot (mm)
- 0.1
- Tab vector width (mm)
- 10.2

Try another scenario
- Desired physical tab width (mm)
- 20
- Desired physical slot width (mm)
- 20
- Measured total kerf width (mm)
- 0.4
- Extra physical clearance at slot (mm)
- 0.2
- Tab vector width (mm)
- 20.4
- Slot vector width (mm)
- 19.8
Calculation method
Calculation method
Tab vector width (mm)
Desired finished tab width + total kerf.
Slot vector width (mm)
Desired finished slot width + extra clearance − total kerf.
Symbols and units
- a
- Desired physical tab width (mm)
- b
- Desired physical slot width (mm)
- c
- Measured total kerf width (mm)
- d
- Extra physical clearance at slot (mm)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- For a centreline cut, an external tab loses one total kerf width while an internal slot gains one. The entered clearance is added once to the slot. Test a coupon; taper, material and machine settings are excluded.
