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

Key Learnings:

Hopefully, we will learn a new concept. In this tutorial:

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

... the motion of the Rocker is NOT a function of the motion of the MMA

We will add the 2D-Cam to the Base-Part. The Rocker is joined to the Slider. The Slider move along Base-Part as the 2D-Cam moves the Rocker.

Note: There is an alternative: we can join the Rocker to the Base-Part, and move the 2D-Cam with the Slider.

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

 <<< Rocker motion in MotionDesigner prepared for the Rocker The Rocker motion has 5 segments - Dwell - Rise - Dwell - Rise - Dwell For convenience we will call it a DRDRD motion. IMPORTANT NOTE We should imagine that the X-axis Units are mm. Then, it is easy to imagine that the X-axis is equal to the Linear Position of the Slider in mm. Let's look ahead: This 2D-Cam looks similar to the Rocker motion we designed in MotionDesigner. We will look at four methods to add the 2D-Cam. We will explain the problems and advantages of each. •Method 1: This method is useless, it will not give you the cam you want! •Method 2: OK •Method 3: Success for Single-axis Machines •Method 4: Success for Multi-axis Machines
