6. Large format CNC (computer controlled Machining)

This week we learned about the CNC which is a machine processes a piece of material to meet specifications by following coded programmed instructions and without the use of a manual operator.

A computer numerical controlled (CNC) machine uses a program to control the operation of machine tools such as lathes and mills. It takes a raw material (metal, plastic, etc.) and cuts, grinds, drills, turns, mills, and/or shapes it into parts that meet exact specifications.

Design in a large scale

For this week we are going to design and manufacture something bing that can be used and have a function to it, like a piece of furniture like a chair or a table. I was going for something simple and decided to create a nightstand.

Design prosses

I used fusion 360 to do the design.

when I opened fusion 360 I clicked on create sketch to start drawing the lines.

I start sketching the design as a 2D object with the spacing so then we can fit all the pieces without the need for nails or anything.

These are all the pieces that we will be cutting

After I finish all the pieces I attached them together to see if they will fit together and they did.

The design file is attached below


To cut the design we useVCarve to cut the plywood.

Fatima and I are going to use the same wooden sheet, so we placed both of our designs to fit into the sheet.

Editing the toolpath

choose inside/left so the machine cuts outside of the deign not inside if it cuts outside the spacing will be larger and the pieces will not fit.

preparation for the cutting process

we placed nails to make sure that the plywood will not move during the cutting presses.

we wore protective glasses and stepped away from the machine for safety. it is important to not leave the machine to leave the lab because anything wrong can happen during the cutting process.

Cutting Process

after making sure that the sheet is well-secured press on start and step away from the machine.

This Video shows the cutting prosses.


These are the things I used for sanding.

This is what the pieces look like before and after sanding.

what is the problem that I faced?

Some pieces didn’t attach together, I was supposed to create more spacing between them. but we already cut all the pieces so instead of cutting all the pieces all over again I sanded more between the joints, and it was a successful solution.

Final result
