Step 6D1.3: Add the Stationary 2D-Cam

Key Larnings:

Hopefully, we will learn an important concept.

The motion of the Rocker is a function of the motion of the Slider.

We will add the Cam to the Base-Part . The Cam-Roller in the Rocker moves with the Slider over the Cam.  

Note: Alternatively, in Step 6D1.2, it was possible to join the Rocker to the Base-Part, and move the Cam with the Slider. However, we joined the Rocker to the Slider.

First: What do we want the Cam to look like?


<<<This is the motion we prepared for the Rocker in Step 6D1.2

The motion has 2 × Ramps


Imagine the X-axis Units are mm and NOT degrees.

Then it is easy to imagine that the X-axis is equal to the motion of the Slider.

Let's look ahead:


This 2D-CamRed-14-1b will looks like the Rocker motion.

We will look at four methods to add the 2D-Cam. We will explain the problems and advantages of each.

Method 1:

Method 3: Success for Single-axis Machines

Method 4: Success for Multi-axis Machines
