5. Large format CNC¶
CNC is Computer Numerical Control and it is a manufacturing process in which pre-programmed computer software dictates the movement of factory tools and machinery.
Where CNC used?¶
The machine can be a milling machine, lathe, router, welder, grinder, laser or waterjet cutter, sheet metal stamping machine, robot, or many other types of machines.
Group assignment¶
- Mr.Abdulla Fadi was the mentor for the CNC machine.
- Available CNC machine in Fablab Bahrain: ShopBot PRSalpha>.
- Used software: VCarve ( helps to adjust toolpath, speed, and place the design )
We did several samples with various speed and feed.
Three parts; Different feed and stable speed in right side. Different speed and stable feed in left side. -Pocket test will be tested as a smile face.
My own chair¶
I used fusion to do the chair that called flat pack chair, and these are the steps of the design.
Note: the joints in this design is too important as the chair will be assembled depends on the joints without any screws/bolts, so i have a tolerance ratio around 0.3mm to have a hard joint that can be assembled easily and unassembled hardly.
Machining steps¶
The following video shows all the steps that i followed under Mr.Abdulalla’s permeations while following safety precautions
