Step 6C1.1: Add the 3 Planes and 5 Elements

Barrel Cams need three Planes and three Mechanism-Editors

With reference to the image to the left:

1r   A Plane for the Cam-Follower and Cam-Roller Follower - offset from the Top Plane*

2r   A Plane for the rotating Barrel-Cam - if possible, make this the Front Plane*

3r   A Plane for the Barrel-Blank - the Right-Plane*

* Use these Planes, if the model is to design a 3D-Cam, and does not need to include other machine elements.



Rib Cams.

This tutorial designs a Barrel Cam with a Cam-Track, a groove, to guide one roller with a cam-flank on each side of the one roller.

It is also possible to model a Barrel Cam with a Cam-Rib - see image to the left.

In this case, there are two Cam-Rollers, with each Cam-Roller against a different cam-flank.

Contact us, if you need help to model the Barrel Cam with a Cam-Rib.

The Five Elements for a 3D-Cam:


There are five elements to Add 3D-Cam. They are three different Planes and Mechanism-Editors.

The image shows all five elements. You must do Visibility toolbar > Show other Kinematic and Sketch-Elements.

Red-14-2 Cam-Roller Profile

Red-14-3 Cam-Shaft Part

Red-14-4 Cam-Blank Profile

Red-14-5 Cam-Blank rotational axis Sketch Line


We also need to design the Motion in MotionDesigner.

The Segments are:

Segment 1: X-axis: 0-120, Y-axis: 0-60 : Poly 3-4-5

Segment 2: X-axis: 120-180, Y-axis: 60-60 : Dwell

Segment 3: X-axis: 180-300, Y-axis: 60-0 : Poly 3-4-5

Segment 4: X-axis 300-360, Y-axis: 0-0 : Dwell
