Making The Design Of The Hanger¶
I created a hanger design for chilldren using fusion 360
- First, i started with scketching the pieces, where the piece on the side is 1135mm on height.
- Then i added a picture of a bunny face, and using the line i drew over the stracture
- For the pieces on the sides, i added a new scketch of a rectangle over the piece did a mirror,and extruded both .
- Then i added a square for th bottom piece and extruded it
- I used the miror feature to copmlete the hanger with a 800mm total lenght, after that i made sure that each piece is a body therefore i can add the joints between the bodies.
- I used the offset features for all the sides that i wanted to do joints on
- I added the figer joints to connect all the pieces together, which are the most suitable type of joints for this design.
- This is the final Design
CNC Machine¶
Material Used - For this design i used 12mm thickness plywood
- Then we attached the plywood sheet
- Bfore we start we turned on the vaccum
-
Vcarve software is used to connect with the CNC
-
For the set up, the width was set to mm and the thickness to 12mm
-
We imported the files to Vcarve
-
‘dog-bone’ filltes are used for the joints to creat clearnes
-
Then we opened the toolpath, choosed profile toolpath operation
-
we did edit the tool variables,the cut depth is set to 13mm to ensure its cut all the way.
-
set it to two passes with 6.5mm depth per pass
-
the tool is 1/4 inch
-
then we did set the toolpath tabs and vectors of the machine are outside/ right with climb direction then saved this setting
-
After that we selected the file saved, the Z axis is set to 12.7mm and started cutting
After Cutting¶
- Then i did sand the wood and put the pieces together
Final Result¶
Problems i Faced¶
- i did face a problem while designing the joints at some corners, therfore i had to redsign them multible times.
