Parameter defining Spindle Clamping force

[Ashish B]

Hi,

Is there any parameter which defines the clamping force to clamp spindle when Spindle Orientation Command ( M19 ) is given.

Thanks
Ash

What control? What machine?

Control - Mitsubhishi M60
Machine - Pinnacle 1100S


Also attaching a Spindle Parameter dictionary to assit you.

Hi

I am undergoing through the same problem.

==> After M19, my spindle orients properly but it jerks suddenly

==> Also if i rotate the Clamped spindle by hand it moves 2 to 3 degrees & again tries to restore its original position.


I think i should increase the clamping force on spindle after M19 - BUT

1. Is it possible to change through Parameter Setting ?
2. What is the recommeded force ?
3. What is maximum force & need to know if any consequences are there if the force exceeds maximum limit ?

Thanks...Need Help Urgently.

There is no spindle clamp. It's being held by electricity, applied to the motor. Yeah, it tries to reposition because that's the only thing it can do.

Hey Greg,

Thanks for the reply.

I UNDERSTAND the point that it is held by electricity.

But as mentioned eariler, the spindle moves 2 to 4 degrees (on both sides) without any external force or any material contact. I realise that it is been clamped firmly by electricity

BUT

the free movement (i.e.. jerk) of spindle without any external force doesn't give the justification to the clamping rigidness of spindle brakes.

I think any parameter need to fix.

Any Ideas.

Hi Grey,

As u mentioned that it tries to retrives its orginal position only because it is been clamped electricity.

Do you have any idea that does it retrieves its original position accurately ?

Hi

I think i previously posted symptons of problem & not the real problem.

I will try to describe my problem as under -

I have a application in which i orient spindle 2 times.
Firstly i orient it at 0 degrees. Secondly, i orient it at 30.3 degrees apart from 1st position.
I need to know/measure the actual rotation of spindle from first position.

I am sure that some parameter at servo drive receiver end must be tracing the actual spindle orient rotation.

But how to dig it out & do you have any idea that which parameter traces that actual rotation.

Thanks

If I understand you correctly - you want to be able to orientate the spindle to zero degree's - then after that orientate to 30.3 degrees.
As far as I am aware the only way to do this is to purchase the 'M19 spindle orient' option from HAAS. I am not sure how much it costs - but you should be able to find out from your dealer.
Once you have the option turned on you just need a line of code similar to this:
M19 P30;

M19 is the orient code
P30 is the amount you want the spindle to turn by in degrees

Before you purchase the option it would be advisable for you to check that you can orient to an accuracy of less than one degree as I am not certain (you want 30.3 degrees). I know you can definately index the spindle to whole degree's but not sure about fractions of degrees.

Hope this helps

Hi,

Thanks for the Reply.

Well, the problem to me is not the spindle orient feature. My machine has a provision to change the orientation pulse value so as to orient spindle offset from the home position.


The problem to me is that sometimes my spindle overshoots by some degrees. So, i need to check the actual spindle travel (from zero position to 30.3 degree position)

As fas as i understand that CNC are built up with PLC Logic. There must be some parameter at the servo drive receving end which tracks the actual spindle rotation & switches off the current to halt the spindle & completes the circuit.


SO, I WANT TO DIG SUCH PARAMETER TRACING ACTUAL SPINDLE MOVEMENT.

Any Comments Welcomed.

do u have a post processor for HAAS VF-3 Gibbscam?
