Step 6A1.5: Add a Cam-Shaft

Summary of this Step

Before we can do Add 2D-Cam, we must add a Cam-Shaft.

The Cam-Shaft is a Part that rotates with constant angular velocity. Identical to Tutorial 1.

Notes:

A: In Step 6A.3 we added a LineRed-14-1b in the Base-Part.

B: It is possible to add a Pin-Joint and a Part at the same time.

STEP 1: Add a Part as the Cam-Shaft

1.Click Kinematic elements toolbar > Add PartRed-14-2.

To add the Pin-Joint and the Part at the same time:

2.Hover above the PointRed-14-3 so that only the Point is red

3.Mouse-button-down, ... drag, ... mouse-button up.

We join the Part to the Line with a Pin-Joint.

STEP 2: Add the Motion-Dimension FB

1.Click Kinematic FB toolbar > Add Motion-Dimension FBRed-14-4

2.Mechanism-Editor: Click the Pin-JointRed-14-5

3.Mechanism-Editor: Click the LineRed-14-6 in the Base-Part.

4.Mechanism-Editor: Click the LineRed-14-7 in the Part.

5.Right-click OK-tiny-11-15 to close the Command-Manager.

The Motion-Dimension FB is next to your mouse-pointer. The Cam-Shaft is now a Part that is kinematically-defined (Solved)

STEP 3: Edit the start angle of the Cam-Shaft

Edit the angle of the Cam-Shaft so it is horizontal when the MMA is at 0.

1. Double-click the Motion-Dimension FB

2.Motion-Dimension dialog > Right-click the Base-Value in the data box

3.Click Zero in the shortcut menu

4.Click OK-tiny-11-15 to close the dialog.

The Cam-Shaft is now horizontal when the MMA = 0.

STEP 4: Connect the Linear-Motion FB to the Motion-Dimension FB

You can connect more than one wire from the output-connector of a Linear-Motion FB.

1.Hover above the output-connect of the Linear-Motion FBRed-14-1 , mouse-button-down, drag, and to the input-connector of the Motion-Dimension FBRed-14-2, mouse button up.

STEP 5: Run toolbar > Cycle - or use the ALT+C key combination.

Save your mechanism

You can connect one wire to the input-connector of a Function-Blocks. A Function-Block may have many wires that connect its output-connector to other Function-Blocks
