How to process the 8-shaped fuel tank on the CNC car? Please make a timetable.

G92 is not good for cars.

Take a closer look at G92' s walking route → thread cutting → thread end point →G0 speed returns to the starting point, so G92' s walking route determines that he can't open the closed inverted 8 fuel tank.

G32 can be rotated. The cutting route of G32 is that you write one step program and he takes one step, so you can write it in G32 according to the size of your inverted 8. I've done a lot of oil dumping. You can keep asking questions.
