Haas Trunnion Post question

[byte]

So, does that mean you have to program everything again in Mc?

[gcode]

yes.. though I suspect the bosses will run out of patience long before I'm done.

Sounds like fun....

Yes, quality takes time, they will have to wait, they always jump up and down for stuff where I work too, but I only work at 1 speed, there's no turbo button.

One of these days you'll have to explain to me what it is you do exactly.

In my imagination, you have a giant mill turn with giant parts made out of titanium or something.

I was thinking it would be cool to have a mini mill turn one day, I expect you'd have to build it yourself out of the conventional ones, expensive too I bet, hmm

You'll be done in no time!

we have an Okuma VTM1200 YB which is pretty cool
I have done some Ti and Inco parts on it, but it's mostly carbon steel
parts for the gas compressor industry

I remember well that morning you showed us around your shop. I gained a whole new meaning to the description "large CNC machine".

The Okuma VTM machine I would really like to have experience with programming. Not to mention your big MU

A neighbor put one of those trunnions (from the video link screenshot) on his Haas. Sold and installed by Haas. Barely works for aluminum and has issues homing and not very accurate.

That doesn't make me feel good about this project
We're doing Ti hog outs for the F35
I'm doing all the roughing on 3X machines and just light swarf and face milling on the trunnion
They are tight tolerance parts though and it the machine can't hold it, it's going to get ugly
I haven't actually made an chips yet.

Ti hog outs for the F35

can I count on you to post my bail??

This is what I wish I had for this project

I have a customer with a new at the time VF2 with a 5 axis trunion....he was running upper receivers on it..7075...

He had all kinds of positional adjustments and speed & feed reductions just to reliably cut and hold tolerance...he was happy to be making them but efficiency wasn't great

I tried a Ti hogout with my VF-3 in the best case block-on-the-table setup. Epic fail. Something between spindle, drawbar or coolant. Just couldn't get tool life worth a crap. Wouldn't even bother doing Ti on their table top joke-trunnions. Too many better options out there, if you have a solid contract. (I didn't)

this is a small job shop my employer purchased at fire sale prices
the shop has been building these parts with really bad 3D files since 2009.
They were programmed by a contract Catia driver and the CAM files are no longer available.
They are stuck in a loser LTA and must deliver the parts on a regular basis
They currently machine them 3D ... with hours of waterline passes on walls that could be swarfed
on a 5X machine.
Days of bench work and straightening are required to produce a part.
