CNC Saw Calculator
Part Specifications
Select your part shape and enter dimensions to calculate saw cut lengths.
Engineering Notes
How It's Calculated
Each angled end produces an offset equal to part width multiplied by the tangent of its cut angle. Offsets are subtracted from the total length according to the selected part shape.
Calculation Assumptions
- Angles are measured from a square cut (0°), not from the part's long edge.
- Part width and total length use the same selected unit.
- Top and bottom lengths are calculated to three decimal places.
Intended Use and Limitations
Use for preliminary CNC saw setup calculations. Confirm cut orientation, machine angle conventions, tolerances, and dimensions before machining. This calculator does not account for saw kerf or material allowances.
Your Saw Inputs
Calculated edge lengths and signed cut angles for the selected part shape.
Measurements correspond to the selected cut shape. Confirm saw angle conventions before machining.
