Cubic Cam-Law, Motion-Law

Cubic : is a 'Polynomial' Motion-Law. A different name is Constant Jerk


Segment-Editor AND Blend-Point Editor

CAN specify the:

Position at the START of the segment.

Velocity at the START of the segment.

The Start-Position and Start-Velocity motion-values can also flow from the End-Position and End-Velocity motion-values of the Previous-Segment

CAN specify the:

Position at the END of the segment.

Velocity at the END of the segment.

CANNOT specify the:

Acceleration at the START and the END of the segment.

Jerk at the START and the END of the segment.


MotionLaw-Cubic-1

Cubic from '0' to '1'

In the image, the Blend-Point values at the START and END are:

Position: 0 ; 1mm

Velocity: 0 ; 0mm/sec

Acceleration: Undefinable

Jerk: Undefinable

Cv = 1.5

Ca = ±6

Cj  = 12

Application Note

Any application where you must have a Constant Jerk [acceleration changing at a constant rate].
