Computer-Controlled Machining
* Week Assignment
Make (design+mill+assemble) something big (~meter-scale)
Computer-Controlled Machining also computer numerical control, and commonly called CNC) is the automated control of machining tools
(such as drills, lathes, mills and 3D printers) by means of a computer. CNC machines are a subtractive technology.
Design Idea:
In this assignment I decided to design my final project frame by using CorelDraw and Solidworks.
First Prototype:
First I used CorelDRAW to design standing frame with wheels.
By using CNC machine to cut the frame I get:
Final Design:
After testing and discussing the errors in first prototype with my instructor Fathiyah Salem, I changed the design to be more reliable and strong.
To design it I decided to use SOLIDWORKS software to design the standing frame.
First step is to choose the plane and draw a circle with suitable dimensions.
In the center of this circle I draw a line.
Then use Trim tool to get half circle.
I added two rectangles.
Fter that, I draw two circles at the end of the rectangles.
Again use Trim tool.
Finally, I used extruded/boss to get the required thickness. I used 12 mm material.
similarly, I draw rest of the parts.
To joint all parts I opened new assembly and add all parts. I used mate tool to assemble the frame.
After simulating the design, I used CNC machine to cut all parts.

I used Aspire software to generate paths and G-code for my machine.
After fixing PVC plate I start cutting.
The parts:
After assembling all parts I get the final standing frame.
