Hook Joint

For this assignment, I got a hook joint. This is the reference picture that I got.

I started with drawing lines in Rhino. I prefer drawing the lines first, and then move on to 3D modeling to see if they match in the virtual world.

So, as for the outlines, I placed the two pieces perpendicular to each other so that it is more convenient for me to check the size of each side.

These are the front view and top view.

Next, I move on to 3D modeling phase.

The tool that I use in this step is Solid-Extrude Planner Curve-Straight. As for making the circle in the inside corner, I create cylinders and then use Boolean-Difference to get the dog bone joint. The dog bone joint helps to make the connection smooth and flexible.

These are the perspective view of the 3D version of the hook joint.

After making sure everything is ready in the virtual world, I start to make the CNC file.

I was quite confused with the definition of "pocket" at first, but, eventually, I figured out that it is the command that allows the machine to cut the exact depth that I set. And the contour is telling the machine whether it is cutting the inside or the outside of the piece.

And there's a photo of CNCing.

The dxf file is attached.
