HMC question

[mirek1017]

Hello all ,I hope  I can  explain my  question 

I am program HMC  ,one part only ,the was 2 operation on it .

On lest  operation I want to make  side hole  ,so this is my front plane  and part view 

 

I want to rotate my table 75 deg  and  drill port  like this 

 Can I  use this number  for calculation  new X and Z position ?

 

 

How I can calculate this numbers ?I am not programing  from center of rotation  so I was wondering  there is some method ?

for now I  do like this  

 

 

Rotate table  ,Y  will be the same  and I can take point from right edge 

I thing  I has  to find out  center of  table rotation ,did I am write ?

I use tooling balls...if I have a tombstone that will need to have angles picked up I make sure I add a toolball location that I can easily reference.

Of course I also have all of my hard tooling modeled and positioned properly and my post will output the actual zero coordinates...the tooling ball check is still good for the guys to occasionally double check to..

I dont   understand   ,can you posting some video ?

With the Tooling Ball I can reference the hole origin

I mostly program using dynamic work offsets across multiple planes so I only have to set 1 work offset. I mainly program for a haas UMC-500 so as you can imagine it's not the most accurate in 3+2,.. I've never used tooling balls for locating like shown but I will CERTAINLY keep it in mind if I ever have to hold a true position and would like a reference/locating feature

I do not have dynamic work offset on my machines ,I know some people use sample macro calculation ,but I am never try it .

[gcode]

If I had to do this I'd make a new work offset, and drill and ream for a tooling ball in the center of the port at B90

Then I'd install the tooling ball, index to the proper angle and use the tooling ball to set a 3rd work offset

You could also have your operator set the part up and tell you where the part is in relation to the B axis COR

then program it that way in Mastercam

Not sure what the overall process looks like but on our 4-axis HMC's we always program a single work offset from POR. The only time our pickup isn't POR is if there's no rotations, then we usually do some type of 3-axis pickup. I always figured programming from POR was industry standard, maybe not?

We also use tooling balls if we need them.

[JParis]

All of our HMC programs come out this way....the offsets are posted out of Mastercam...the final adjustments are generally under .002"

We type in the reference location notes

I've been setting all of our HMC's up with this.  Very useful, like a poor man's DWO.

 

One of the biggest benefits, IMO, is less opportunity for operator error.  We use G10 lines to write offsets on all of our programs.  So with this method, the setup guy is entering 1 set of coordinates.  Not 13, or however many he needs.

I can use this on any  Fanuc control ?

One is very old  Fanuc Series 15-M

I believe, as long as it is Macro-B capable

I've been using this method for ages. Now that we have a couple of new HMC's that actually support DWO, I'm still trying to get it work the way I want (in Mazatrol world it seems to have its own will...)
