On topic- rigid tapping ?

How do I determine/test if my VMC has rigid tapping? 86 Mori Seiki MV-JR/Yasnac MX2 control. The Helical interpolation option is installed.
does someone have a code snippet I can run as a test?
And if I want to thread mill, is rigid tapping required?

Don't know what MX2 expects. Fanuc likes this: M29 = orient spindle G99 G84 Z5.51 R6.71 F4.1667

No, just need helical inerpolation, which say you have.

M19 orients ( positions ) the spindle. M29 Synchronizes the spindle for rigid tapping.

    A call to the manufacturer might help get the correct G-codes. Ask if they have any user manuals they could send you as well.

    No, completely different process.
    If you've never thread milled before, peruse the following sites. Cut air the first few times, then cut something really soft. Make sure your hole is deeper than the depth your thread mill will go when entering the hole.

I have been using tapping heads for years, just tired of dealing with their sometimes minor issues. Thought it was time to get current. I have some Bilz style T/C tap holders. Will they work for rigid tapping, or do you need rigid tap holders too?
What does the Q parameter do on the Fadal G84.1 for rigid tapping?

I use compression/tension holders about half the time. They can compensate for minor lead errors of the machine.

It's the pitch of the thread (1/2-13 tap, 1 divided by 13 = . 0769). It allows the machine to calculate the feedrate at that pitch.
BTW If you're going to E-mail the same exact question as your post, it's easier if you send them both together so I can respond to both of them together.

One great thing about Yasnac is you can download manuals online for free.
You have a Yasnac MX2 control, book mark this page and/or download the manuals.
http://www.yaskawa.com/site/dmsearch.nsf/search.html !OpenForm&Seq=3&pg=Controllers
The MX2 Operators Manual is dated 1985 and looking through it I don't see rigid taping and like a previous poster mentioned Thread Milling can be done if you have full 3 Axis.
Funny reading the descriptions of the canned cycles though "Wood Pecker Feed"

Every Yasnac I have used uses the following
G93 G98 G84 Z-1.0 R.1 F.05 G80 G94
The G93 puts the machine in IPR (Inches Per Rev) mode G94 switches back to IPM (inches per minute)
A bit confusing because G93 puts a Fanuc into inverse time

So is IPR required for rigid tapping?
On the Yasnac a M35 is spindle orient. I haven't found a M code for rigid yet.
