help with threading g76 settings
--------------------------------------------------------------------------------
I need a little help writing the the g76 line to thread with yasnac lx3 controller.
I have been lax in learning basic canned cycles as my other 2 turning centers have really easy to use conversational programing and to date I have not needed to know the how and why , just enter a few parameters , maj, minor pitch and depth per pass and cut the threads.
I have spent the day going thru the 4 pages in the manual that relate to g76 and have written the following which is intended to cut .75x20 tpi . Everything appears OK but it cuts the final pass at a depth of .006" , 2 x my D value.
Is there a way to enter a value for depth of finish pass and any way to callout spring passes (multiple finish passes at the final depth)?
