More about lathe diameter mode on the Fanuc 0-TC (I found the manual): In diameter mode:
X specifies a diameter U specifies an incremental diameter (not relevant in EMC) coordinate system setting is done in diameter (like our G10L2 and G92?) X tool offsets can be in radius or diameter depending on setup (I think they don't have anything like G10L1) for arc R format, R is a radius for arc IK format, I,K are radius values and always incremental from the start point feed rates are delta radius/revolution or delta radius/minute even if the feed is along X in canned cycles, X/U are diameter but some other things, like the amount of taper on a tapered thread, are radius Note that I don't know if this control did everything the normal/common way or the way that's still common today. I thought it might help you anyway to know what it says. So I can think of a few unanswered questions: John K is adding absolute arc center mode - what is the I in that case if using diameter programming? Are X repeats in canned cycles radius or diameter? Like G17 G91 G85 R0 Z-1 X.005 L10 (I bore like this all the time) Are I,J,K in G76 (offsets from the drive line and depth) radius or diameter? Is K in G33 (distance per rev) still radius if motion is along X? (Pretty sure it should be) Are diameters or radii written to the var file for offsets? What about the tool change location that is read from the ini file? how much tweaking is required for the AXIS preview, display of machine extents, length and time estimates on the properties screen, etc? ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
