Can any-one help me out on this??

We here have got a HRT210HSH rotary, on which we machine parts at 85 - 90ipm feed. but the problem is after we have incremented the rotary to about 16500 odd degrees to come back to origin the axis rotates thru he whole distance incremented.
Is there a way where in I can bring the axis to origin in a single turn/rotation in the program.
note: it can be done in MDI mode, I have tried it. But I haven't succeeded to do the same in the program.

I think it is called Quick Rotary G28. Look in your manual, you have to change a Parameter and a Setting. I will have a look on a machine in a couple of hours to see if I can find them.

Here are the instructions copied from the Haas Mill Manual


108 Quick Rotary G28

Turning this setting ON will return the rotary unit back to zero using the shortest distance.

For example if the rotary unit is at 10° and a zero return is commanded, the rotary table will rotate 350° if this setting is OFF.

If the setting is ON the table will rotate -10°.

In order to use Setting 108, the parameter bit CIRC. WRAP. (10) must be set to 1 on parameter 43 for the A axis and Parameter 151 for the B-axis.

If the parameter bit(s) are not set to 1 the control will ignore setting 108.

I have already tried that before.
It works fine in MDI mode, but somehow it doesn't accept this comand in program mode.
I will paste part of the prog lines below, see if there's something wrong in my programs.

So do you think there's somethin wrong with my prog. Have you got my reply to your earlier post?

I don't see any reply to my first post.

I do not know if there is anything wrong with your program.

To return the rotary quickly on a G28 command you need to set the Parameter and the Setting as decribed in the instructions I cpied from the manual.

Setting 108 ON

Parameter 43 CIRC WRAP 1

When you do this a G91 G28 A0. should return the rotary to zero in less than one revolution.

[wscsr]

Yes Setting 108 is ON And CIRC WRAP is set to 1.
And I use the same g28 command to go to home position.
Its mentioned in my earlier post above.

Thanks
Wil

some versions software after you index so many degrees it wants to unwrap by itself whether the settings and parameters are set correctly or not. unless you do a g28 after revolution. try putting the g28 a0 after every 2000 degrees or so otherwise try to get a software upgrade for free.

[HuFlungDung]

If you command the A axis to move to some exact multiple of 360°, what happens if you then use a
G92 A0


It seems to me that this is what you actually want to do, since a G28 call returns the axis to home, which is logically unwinding all the moves that have displaced it from home position.

Will that mess up the Haas, or can it deal with it?

we used to tell people to stay away from g92 and g52 you can try
g0 g90 g53 a0

Why the suggestion to stay away from G52?

[serviceman]

it confuses people if they do not know what they are doing and could cause a crash g52 is a little more complicated than regular offsets and is really there just to be compatible with older fanuc machines. there is really no reason to use it unless you run out of offsets. you can also use g10

That is interesting. One comment is that anything confuses people who do not know what they are doing so that is not a good reason to stay away from something. If a person stayed away from everything that was confusing on first encounter I think they would not learn much.

I spent some time figuring out the advantages and disadvantages of G52 and now find it very useful. I agree that there are a great number of main work offsets available and it is possible to enter them and change them during a cycle with G10 but I am not sure anything is gained doing it this way.

[serviceman]

whatever works for you there are a million different ways of programming machines. i am used to trying to keep it as simple as possible and guess i am stuck in the new machine no g code experience mindset for many customers.
