Hi,
I have a Tormach 1100 PCNC and BobCadCam v20 software. I know the value of being able to understand G code and not rely fully on a Cam program so that you can scan your code for errors. What I would like to know is, will someone help me with a simple program. I am a complete tyro when it comes to G code. I have drilled a 17/64 hole through a steel part and drilled the same hole 7/16 dia. .280 deep. I now want to use a .250 end mill to finish the counterbore ( I do not have a counterbore tool nor do I have a 7/16 end mill ). The problem is, I do not understand how the I and J codes work. I only know that they have something to do with circles. If someone is willing would they write a sample program for the above counterbore operation .300 deep? It would be appreciated.
Thanks,
Ernie
