Anyone have an idea for this problem.
this machin when a g96 is used to turn machine will slow down the closer it gets to centerline the speed back up the farther it gets away from centerline.

It is a CMS GT 27 lathe

Thank you for any help

That is called "constant surface speed" machining.
If you want to use fixed RPM, use a G97 instead.

Yes I know it is Constant surface speed.

Problem is that it should not slow down closer to centerline then speed back up the farther from center you go.That is completely backwards of how a G96 should work or any lathe I've ever seen.

Sorry
That was the part of the post that I missed, makes sense now.
Almost sounds like your Y axis is reversed.
Not much help - eh
