Race Car Brake Bracket
To begin my design, I first made a rectangle with the appropriate height and width dimensions. Next, I added circles and dimensioned them to the correct diameters. I then added circles around the originals
I used the line tool to connect the circles to the outer edge and then used a new tangent constraint to make sure they lined up with exactly one point on the outer circle. I was very confident in this step because we just learned how to use constraints in IED class. I then used the trim tool to get rid of the extra lines and then I extruded. Finally, I started a brand new sketch and created the raised circles by making two circles and a line that could trim away the bottom of the upper circle. To finish it off, I extruded the two circles I created on my second sketch, and I was done! |
Next, I changed the drill bit and speed of the CNC Mill. For the mill, the spindle speed is 5000 RPM and the Feed Rate is 39, which was different from the router settings. Instead of using the 2D path (like the router), we had to use the 3D - Adaptive Clearing tab for the mill. After changing the max rough stepdown to .25" and the stock to leave to 0, I simulated the bracket and converted it to G-Code. |
CNC 'Mini' Mill!!
One of the tools that I use to deciufer between the mill and the router is by remembering that Mill=Mini. I remember this by the M from mill is the same as the M from mini!
I found the appropriate sized piece of foam and put double-sided tape on it. I jogged the machine using the neat circular disc. It looked like a video game controller. Finally, my years of experience have come in handy, You could select X, Y, and Z, and the outer circle jogs the machine faster than the inner circle.
I moved the drill bit to the bottom left corner because that's where I set my stock point in Fusion 360. I brought the Z down so that a strip of tape couldn't fit between the drill and the foam. Finally, I closed the doors, pressed play, and waited with a hand on the space bar for something to go wrong. Bel;ow is some pictures of it all set up.

Summary
This project was the first project in IDEA that had a real-life application. In this unit, I learned how to read and interpret blueprints in order to 3D model the figure in Inventor. I was also able to apply my knowl;edge of constraints that I learned in IED class to this assignment and be able to help others.
In addition, I also learned new tools in Fusion 360. For the maze project, we used the 2D Contour from the geometry tab to create our paths. For this project, we familiarized ourselves with the 3D Adaptive Clearing. Finally, when converting our Fusion 360 file to G Code, we selected "Tormach Path Pilot" for the mill, instead of " Forest Scientific", as we did for the router.
