Rigid tapping pitch output

Phenom

Hello, I am sure someone must have come across this and found a solution.

 

 

I am attempting to get IPR (inch per revolution) output on my post for taps. I added an F word and swtiched it to feed_ipr, but it still calculates the IPM. Should I use a custom command and use [set feed_mode "IPR"]? And then would I set it back after to "IPM". I placed the G95 IPR in the tapping command but it does seem to switch the mode, it just places G95 in the code.

auto.pngLooks like I answered my own question after some more digging. Turns out I needed the have the cycle feed rate modes set to auto. If only everything were as easy as one click.

Note the cycle feed code set to "Auto" will use whatever the operation is set to.

If the op is set to IPM, you will get F in IPM.

If the op is set to IPR, you will get F in IPR.

 

If you *have* to have IPR *always*...(but just for the tap cycle)

You may have to write some code to check.

I'm not at work right now, I'll have to look it up next week & post if you need it.

Auto is only an option for cycles.  If I want to output a G94 or G95 when selecting IPM or IPR in the operation dialog for milling, is there an easy solution for that?  Or does it involve writing in some logic/changing variables?

 

Thanks

I have the feedrate mode switch in my linear and circular motion.

And I always get the proper G94 and G95

Thanks Paul,

Do you recall what you used as the base post for this?  I have tried a few different base posts, and also a few OOTB machines and none of them work out of the box.  I am able to create my own logic to make it work, but it doesn't seem like that should be necessary for something this basic.

It's actually a post I downloaded about four years ago off the PLM site. It was for a Mazak Variaxis 630

Using the machine verify I needed it... machine tapped fine (Mazak) without it. But my simulation would crawl.

Hi

 

I did my post with pitch values from tool database. It means all my taping operations have to be done with tap tools. In postprocessor S value is constant for taping, I use 1000RPM.  In operations there is no need for F and S values. S and F values are set automatically by postprocessor even if thread is left handed.
