Cutter Comp in Toolpaths-Circmill_Threadmill

I was wondering if anyone out there would know if 8.1 would have the following fixed:

When I am in my parameters for threadmilling and I'm doing an internal thread, it does not allow me to choose an entry exit line. It only has entry exit arc. The reason why this is a problem is that my machine cannot produce a G3 G41 line or else it will go into alarm. Any suggestions or am I S.O.L.?

It's not a big deal but it would be nice if the option for both entry and exit lines and arcs would be available. It just saves the trouble of adding or inserting a G1 G41 line in the NC file. smile.gif

What is the diameter of the threaded hole versus the threadmill cutter diameter? General rule-of-thumb is that the cutter diameter should not be less than .200" smaller than the hole size. Your enter/exit arc may be also too large for this, not having enough room to pick up a linear X or Y move. I am running V8 threadmilling with no problems (yet).

Chris I haven't used the thread mill cycle,

but in circle mill I've had the same problem on my Haas. The solution is to change the

entry/exit arc sweep from 180 to 90 and

check "start at center". MC will output a straight line move with G41/42 before starting the arc sweeep
