aggregate again

[Yogesh K. Raman]

using X MR2,

 

I'm trying to build a post for the following Milling machine:

 

It has a right angle head which it can change automatically to using M62 code.

the head can turn and machine right, back, left, and front using the following codes:

M41 C0.

M41 C90.

M41 C180.

M41 C270.

Using the Fanuc 4X router post.

 

Here's my question:

1. Should I define the machine as having an indexible C axis every 90 deg with single outlet Agg, or set the Aggregate as having 4 outlets? Is there any difference?

2. The programming reqiures the axis to be transformed so that the z is always perpendicular to the working face. Currently all my Agg output refers to the machine absolute axes. How do I get this?

There were 2 big SNK gantry mills with right angle heads at my last job.

The right angle head could be indexed in 5° increments.

We programmed the right angle head like it was a

4 axis horizontal mill with the part rotating about the origin.

looks like this is the easiest way. Going to try this out.... thanks

Be careful with this approach.

The SNK control had very sophisticated software.

No matter what angle the right angle head was postionined, the control always looked at it

in the usual X+, Y+ Z+ orientation.

In other words, looking straght down the cutting tools, X+ was always to the right, no matter what

angle the head was at. That is why we were able to

use a horizontal mill post.

If your control can't do this, the X+ direction

will reverse as the head changes from Front to Back and an HMC post won't work.

I'm not sure where the X are pointing at, sample codes they gave are boring operations... I think I need to do another visit to check this out... thanks for the warning,

I'm going to your shop to play with that

Exodus,

 

If you checked out their website, they say that the manual is "optional" ...
