G02 Code Example

INFINITY LOOP USING G02 CODE IN CNC MILLING WITH FANUC CONTROLLER

---

G02 Code is used to create a circular path in the program. In this program, we are gonna make an infinite loop. The radius of the circle is 20 mm. The diameter of the tool is 4mm. The offset is set in the middle of the workpiece.
Now, we did this job with the help of both G02 and G03 code in a milling machine.
