To Create a Cam Profile

When you create a cam profile, all linear values are deposited on the same scale.

We conduct a circle with the center O1, the radius of which is equal to the initial radius of the cam.

Denote the direction of rotation of the cam [omega].

The constructed circle is divided into as many equal parts as the abscissa axis of the motion graph has. The points are numbered in the direction opposite to the direction of rotation of the cam.

Trajectories of pusher motion in facing motion are passed through obtained points of tangency to circle with center at point O1.

From points 0.1, 2,..., 17 of the intersection of the trajectory with the circle of the initial radius, segments 11, "2-2," 33, "..., 1717" corresponding to segments 11, 2-2, 33,..., 1717 of the movement graph are deposited.

The resulting points are connected by a smooth curve, which will be the center profile of the cam.

According to the graph of analogues of movements, phase angles are marked.
