CalculationSawing time
Free sawing time calculator
Calculates cutting and batch time from the material cross-section and your measured area cutting rate.
How to use the result
Values are a worked example, not recommended cutting settings. The area cutting rate must match the material, section, blade, clamping and machine.
Area cutting rate in cm²/min describes the cross-section cut per minute. It is neither band speed in m/min nor feed in mm/min.
For profiles, enter material area excluding voids. For bundles, use the sum of all material sections; account separately for facing cuts and extra clamping.
Formulas
rectangular area = width × height / 100; round area = π × diameter² / 400 [cm²]cutting time per cut = area / cutting ratebatch time = setup + number of cuts × (cutting time + handling time) Sources: DoALL: Sawing Machines FAQ, cutting rate as cross-sectional area per minute. https://www.doallsaws.com/faq/sawing-machines; Machinery’s Handbook, “Band Saw Speed and Feed Rate”: cut area divided by cutting time.
