Project Title: Crafting a Dynamic Pear-Shaped Cam Prototype
Welcome! In this Project, I’ll guide you through the fascinating process of designing and prototyping a dynamic pear-shaped cam mechanism. This captivating project marries digital design in Autodesk Fusion 360 with Trotec Ruby laser cutter. Let’s dive in!
Step 1: Conceptualization and Design
We begin with Autodesk Fusion 360 which allows us to sketch, model, and simulate our design with precision. The first step is to conceptualize the cam’s shape and dimensions.
Here’s what the design looks like:

Step 2: Creating the Design Files
Once we are satisfied with our Fusion 360 design, we export it as a DXF file. This format is ideal for transferring our design seamlessly into the next phase of our project.
Step 3: Laser Cutting with Trotec Ruby
Now, we use Trotec Ruby laser cutter. This remarkable machine allows us to bring our digital design into reality. Here are the steps:
a. Set up the Trotec Ruby with the appropriate material (in this case, chipboard and Acrylic).
b. Load the DXF file into the laser cutter software, ensuring the design is properly positioned.
c. Configure the laser cutter settings, including power, speed, and focus, to suit the material and achieve precise cuts.
d. Execute the cutting process. The high-precision laser follows the design outline, resulting in flawlessly cut pieces.
Step 4: Assembling the Cam Mechanism
With our laser-cut cam pieces in hand, it’s time to assemble the mechanism:
a. Attach the pear-shaped cam to an axle or dowel. Ensure it’s secure and centered.
b. Mount the axle with the cam on a chipboard base or Acrylic base, positioning it accurately.
c. Install the clip or other components as necessary, depending on your design.
d. Test the movement by rotating the axle. Observe how the cam’s shape influences the clip’s motion—a beautiful interplay of design and mechanics.
Step 5: The Final Product
Behold! The final product is a captivating pear-shaped cam mechanism that moves with grace and precision.
