can i create a driven point in space?

I want to use a CNGP432 insert to cut an ID. The holder for this insert is a 75 degree lead holder(MCRNL 16-4D). Attached is a PDF showing the tool and how I want set the driven point. I this possible in NX? Current program is in NCL, I'm trying to convert over.

No, there isn't any way to define that tracking point.

I'm sure there's an ER on this, but I don't know the number (can someone from Siemens track down the "master" ER for this?)

 

Best I can think of is use the tracking point "9" (center of radius), then use the X & Y offsets to "move" it to the point you want.

NOTE: IIRC, the last time I played with this, the X & Y offsets are ignored by the post, so you'll have to add code to your post to modify the output position as required (and if this is in a "B" axis holder, it gets even messier)

The master ER is 7692229.

Thanks Ken for the response. So would I need a "custom command" for my lathe post that would plug in the numbers that are put into the X & Y boxes on the tool page? My post does'nt support those boxes either.

I haven't done it, so I don't know the best way.

It could be you can just change the (say) X word from "$mom_pos(0)" to "$mom_pos(0) + $x_offset_variable"  (note "x_offset_variable" is NOT the name of the variable you need - offhand I don't know what variable it is)

It could be you need to add/edit PB_CMD_before_motion or PB_CMD_before_output

 

Note you will have to fix a lot of words

- X

- Z

- I, K (arc centers)

- I'm sure some others.

 

If you have a "B" rotary axis (e.g. Integrex style machine) you will probably have to use the "custom command" approach as you need sines & cosines to map the X & Y offsets correctly

And don't forget to file a "me too" IR with GTAC on ER 7692229
