General Layout

2D Design

Initially, I created a simple CorelDraw model of the course. I would most likely adapt this to include fillets and press-fits, likely through re-creating a 2D sketch in Fusion 360.

3D Design

General

I made a very general 3D model of the course. I would not transfer it to anything, it is simply a 3D sketch. I included extrusions, both cut into the course for lakes/bunkers and upwards for the tee box and green. The nuances such as the cart path, which is typically a slight groove, would most likely be done using the shop bot.

I also imported the programmed golf cart. I do not have the other two elements in this iteration.

ShopBot Design

I made a design that I intend to mill on the Shopbot. I would use a tablesaw to cut out dowels and connect the layers. This would ensure a proper fit without complicating the design.

Planning

It occured to me that I could modify a .dxf file for the Shopbot to get ahead on Computer-Controlled Machining. While I’m aware that this is not next week, I already have a design of what I intend to print. The sooner I create a physical representation of my project, the sooner I can work on the electronic aspect.

Since Mr. Budzichowski gave me advice early on about using the Shopbot to customize a joint, I can replicate the design in Fusion 360. I already have the CorelDraw files for the tee box and the green, I just need to navigate the press-fit joints and bunkers/lakes.

Now that I am familar with the Fusion 360 to CorelDraw conversion, I will start with creating the final files for my green and tee box with room for the press-fit joint.

Right off the bat, I realized that the half-inch difference between the depth of the lake and that of the bunkers was pointless. It overcomplicates the design, requiring an extra layer. While the lake should have greater depth, it would regardless since I’m filling the bunkers. With sand. This is generally how bunkers work.

Since I am working with 2D sketches, I need two three-inch layers with an indent throughout the sides. I would then need a dowel of close to their combined depth.

I considered that I can simply drill the pin, meaning that there’s no need to include it either. I may research the necessary area and draw a mark beforehand, but I doubt I’d need any additional planning for the pin.

The only other aspect is the dowels themselves. I remembered the pen turning activity that we did before Fab Academy, and how we would use a table saw to cut the cylindrical shape. I could find a cylinder of the correct thickness which I would measure, mark, and cut. I imagine this would be the easiest aspect of the process.

  • File setup
  • Import 3D course model

  • Remove appearance customization

  • First model

  • Delete tee box and green
  • Ensure structure is 3 inches in height
  • Ensure depth of inward extrusions measure 2 inches
  • Sketch circles in the center of every corner with an outwards fillet, five total
  • Sketch circle with 3 inch diameter in center of tee box and green - since they are deleted, just estimate
  • Extrude these circles 2 inches inwards
  • Copy

I initially offset the entire outline and extruded inwards until I realized that this was completely unnecessary for a standard press fit.

I replaced these with the circles I mentioned.

  • Second model

  • Delete all inwards extrusions except the 5 side circles
    alt text

  • Circles

  • Create sketch on a plane, not a body
  • Sketch circle with 10 inch diameter
  • Sketch circle with 12 inch diameter
  • Extrude both 3 inches
  • Sketch circle with 3 inch diameter in the center of both circles
  • Extrude both inwards 2 inches
