I have one paticular part I machine thousands of that starts life as a forging . I jig ten of them up on a rotary fixture aprox 6" wide x 18" long thats hung between a tailstock and an hr210 rotary . There are 5 parts on each side of the fixture. At one position I have to bore a hole and thread mill a boss on each of the 10 parts . Forgings are nice but not exact so each time I clamp a new batch of parts to the fixture I have to take my edge finder and set the y axis offset for each of the 10 parts individualy .

I dont have the probe but am considering adding it if it could possibly cut this 10-15 minute procedure down to 5 minutes or less, I currently can run 12 setups a day and I am losing 2+ hours a day.

Is it possible with the probe to write a little routine that will allow the machine to touch off in a paticular place on all 10 parts seperatley and enter the proper offsets in G154 P** automaticly ? The boss on the 10 individual parts is within .010" of the same place everytime .

What would I need to do to have the machine run over touch off on part 1 , enter the Y offset in p58 , touch off on the next part enter the y offset in p59 , etc, rotate the a axis 180 and do the other 5 parts ? Would this be a situation where a macro would need to be written and if so would I need to have Macros activated to do this with the probe?

Thanks for any help , I have no exp with a probe (alien or otherwise) other than the one on my big lathe that sets tool offsets

Probing does a very good job of what you're describing

you have to have macros to run the probe, so the two come as a bundle

the renishaw we got came with a whole set of pre-written macros that will do what you need to, but if you write your own macros you can set y offsets for 10 parts in much less than 5 minutes

you'll use a macro call for each part touch-off, part of that macro call will include which offset you're updating

I am a CNC newbie but would be glad to send you the HAAS stuff on probing...manuals....examples..etc. Just drop me an email.

That is one thing I find I truly love about the Haas Machines.

The probing is the best I have ever used on any machine, Bar None.

What you want to do is extremely easy on the Haas machine.

This is an early program of 4 parts that are castings and I have to probe every time they run. You know castings suck in a machine world. The core shift is always different from batch to batch and the foundry tolerance of +/- .030" is no where near what we want. So probing is the answer. I have other programs that probe 12 parts but this early one is easy to see.

Cool.
I like this way because I'm afraid of hurting the probe so I use protected moves but still in the macros that came with the machine.

Some here can program directly in the macros but I'm not there yet. My macros are simple ones, just rotating the 4th axis or pecking drills.

BTW: I got this far because of help I recieved here on this forum.

I really wish I had ordered the probe with the machine , I will be adding it in a few weeks when I get caught up from the expense of setting up the new machine

[facegarden]

Yeah, i just set up a protected move and zero cycle to re-zero 4 parts at a time in a fixture, it works great! We used to avoid fixtures like that because the part weren't repeatable to within more than a few thou between clampings, but with the probe it doesn't matter!

The probing on the Haas macines is just down right awesome.
I use the probing daily, to set offset on engine parts we machine.
On top of the probing of parts, we are a cylinder head shop, and probe head ports, in 5 axis mode, to get excate port data on on ports.
I would be lost with out the probe for sure.

[BOATDUDEGUY]

our macros were deleted by someone before I worked here
and hass technicians are hard to get ahold of around here
the guy even said he would email us them but you knooowww

sooo can I take one of these examples and use it?
