Week 8 - Computer Controlled Machining
This week assignment was to make something big
Joint test
Software tools:123 make, VCarve Pro and SB3 control software
Hardware tools: Shopbot PRSalpha 120x60
First I made a simple joint test just to try things out, it worked ok but I accidentaly made a cut on the inside of the line but it still fitted together
smal scale table exsperement
I made a successful experiment with 123d make were I made a simple form of 3d object and then made 123d make turn into slices. That way I could make a table and a shelf in a very simple way.
I ended up on making a small scale circular table that I might want to make full scale for library computers. It worked out well and was a very fun experiment.
Making something big
Looking around the lab we really need a better place for the milling bits. I decided to make a small standing table. The idea is that the workbench should always be clear.
I wanted to try out v - carve built in cad features so I desided to draw the whole table there. I was very impressed by the tools and it is nice to have a cam tool were you can do a little bit of drawing too. I also like v - carve because it is visible and user friendly.
Macining
I did a special toolpath for drill so I could screw the screws in clear areas of the work.
Cuting was pretty straight forward. I did not run in to any troubles.
Setings
Assembly
I don't really know what this joint is called but I had seen it before and wanted to try it. It worked very well but was a bit thigh so I had use a lip balm to make it fit
Some joints were a bit to tight and I had to sand them down.
After I had assembled it I tested it out. It was very sturdy and could easily hold me without being wobbly.
outcome
The outcome was great. It is defenately a table that will be used and I might make more. The only flaw now is that the design is not parametric. I would also like to add shelves under the table for storage. The workbench is now clean and looks nice.
