Hello -

I have to convert some horizontal boring bar programs from a customer. Their control is a Fanuc 31i and they use K1 or K0 in their canned cycle lines. For example:

G98G81X-2.8939Y4.9830Z-1.1920R.1000F18.3M8K1
X14.3892Y9.8399
(and so on...)

What is the purpose of the "K1"?

Thanks for any help.
