Operation setup
This setup shows the machine connected to a laptop via a usb cable. this will enable us to control and feed the machine via the laptop
Toolpath and Milling
Universal G-code sender was used to send the G-Code to Pinnochio(the milling machine)
Zeroing Technique
We used the paper zeroing method to help in zeroing the bit(Z-travel). this is the process of using that technique, a piece of paper is placed on the copper piece and then the bit in the spindle is lowered until the tip of the bit touches the paper. the paper is then removed and the head is moved 0.08mm downwards to compensate for the thickness of the paper.
Milling Process
A film of oil(machine oil) was put on the copper face to have a cleaner cut.
