can the wcs help me

[tryon]

I came across a problem last nite. I programmed a part for one of our horizontals. its 4 ops on a kurt 8 station cluster vise.

 

I programmed it with the parts at B0,90,180 and 270. one op at a time moving the parts along. well come to find out the only available pallet has the vises at B45,135,225,and 315.

 

im wondering what the easiest way to correct this is? im not using the wcs for this but maybe i could rotate the wcs by 45 degrees in the top view and regenarate?

Tyron,

You could generat a WCS at 45 degrees, but depending on how many operations you have, going through and changing the view in all the ops may take forever. Can you insert a datum shift at the machine? What controller does your machine have?

its a mazak 640M. its not a rotary just indexing

 

its around 20 ops total. 1 work offset per face. I am hoping i can go in and change the wcs in all the ops instead of rotating all the geometry and picking new T-planes. Im not at work now so ill have to take notes.

[Bruce Caulley]

We have a few 640m's but they are all true 4 axis so I can't offer any advice on a fix at the control. Sounds like you might need to use the WCS afterall unless someone else can offer a suggestion.

How about posting the program, and use the nc editor to change your B0 to B45 ....

I don't program a Mazak HMC but can you add the 45 degree increment in the machine fixture offsets?

or even toolpath transform/rotate

I know nothing about Mazak (even though I was told that it is a Meldas control with a different name), but that is exactly what I would do.

Mazak HMC w/indexers don't have a 4th axis shift avail at the machine that I know of. I would just modify the nc with an editor.

 

Or can you rotate the program or nci to post?

No B offset in there with the XY and Z so G54 B0 syncs the program to the pallet orientation ?

 

I find that hard to believe.

[Psychomill]

Believe it (or not). We have several indexing table HMC, none of them have a 4th (B-axis) offset on the work offset pages. All B moves are in the program. If you have to change it, you have to change the program. Really sucks when you do a set up, you're not sure what B you're at except from the position page in the active commands area.

 

I used to use a macro to for the B so that if I needed to shift, I just put a number in variable(s).

 

Also, setups can be a little freaky because on Mazak indexers, the 'feed hold' button won't stop the B-axis. Only reset or e-stop... otherwise...

[tryon]

There is no workoffset for the indexers. We do have one HMC with a rotary and i could just workoffset the B on that one but i cant use that machine.

 

I guess the easiest thing to get me going is the old Find/replace move. But im going to figure out a mastercam way somehow.

 

thanks

Tryon,

We have had this problem for a long time. We modified our post to prompt for the actual B axis face when we post. The post does the math and updates all work offset angles.
