Cam Profile Data: cycloidal
0.5 to 0.95
Cam motion curve profiles — displacement, velocity, acceleration, and jerk factors at 21 angle-fraction points for 9 standard cam motion types (uniform velocity, parabolic, simple harmonic, cycloidal, modified sinusoidal, modified trapezoidal, polynomial 3-4-5, polynomial 4-5-6-7, dwell). Includes max characteristic coefficients Cv, Ca, Cj per motion type.
| motion type | cam angle fraction | acceleration factor Ca (dimensionless) | displacement fraction s over h (dimensionless) | jerk factor Cj (dimensionless) | max Ca (dimensionless) | max Cj (dimensionless) | max Cv (dimensionless) | pressure angle tendency | recommended speed | velocity factor Cv (dimensionless) | vibration tendency |
