Technical calculator
A reproducible geometric check that includes actual blade projection. Enter rpm and feed rate to also calculate peripheral speed and feed per tooth.
Theoretically engaged teeth
— —The calculation uses the two intersections between the blade circumference and the workpiece surfaces. Projection Ü determines the actual position of the blade centre relative to the material.
Ze = Z × [asin(y₂/R) − asin(y₁/R)] / 2πWhen rotational speed and feed rate are provided, vc = πDn/60,000 and fz = 1,000vf/(nZ) are also calculated. These values can be compared with the blade, machine and material documentation.
Valid for 90° cutting of panels and solid workpieces with a continuous cutting path. Bevel cuts and special geometries require a dedicated calculation.
The number of teeth in the cut does not by itself determine whether a blade is suitable. For crosscutting and panels, approximately 3–4 engaged teeth is a common manufacturer starting guideline; it does not automatically apply to ripping, where chip clearance is the main concern. Always make the final check against the specifications of the blade family and machine.
