Post Build: What should I put in my Post to generate a correct G code that performs holes? radius R

Ok well first:

 

I am creating a Post Processor in post builder, generating a strategy (hole making) and testing on a 5 axis machine.

I'm not sure if I should adjust any option in the post for this case (5 axes).
The corresponding line comes out of the form:

G17 G03 X-35 Y-43 R.131

And well, I do not know if I'm missing something in the post or in the strategy (hole making)

I just got a mistake, although I have skipped several different, I have not been able to make the machine drill holes.

CNC ALARM 14040


Tried to change P.C. Upon linked GAP instructions

Sorry, we do not know the model or brand of the controller.

It is likely that if someone wants to help me you will need more information, ask and it will be given to you.

I can advise you:
1. Your cnc not supported R, may be. Try to use incremental or abs I and J.
2. Make short example manually, square 100x100 with radius at corners 10mm, more easy to understand problem.
3. If your CNC is 5 axis, how you switch ON RTCP? Sometime rtcp incompatible with G02.G03.

Thanks Chigishev

Well, our cnc does support "R". We have checked it.

Can you tell me what is RTCP?

Re: Post Build: What should I put in my Post to generate a correct G code that performs holes? radiu

You wrote that your CNC is 5axis CNC. To control tool tip point "smart" CNC use a special function, RTCP or Rotary Tool Control Point - TRAORI for SIEMENS, G43.4 for FANUC or MAZAK, M128 for heidenhain.

 

Re: Post Build: What should I put in my Post to generate a correct G code that performs holes? radiu

I open SIEMENS 828 manual
Error 14040 - if you use circle Radius programming - it mean that start and end point idetiacal.

In Post Builber set output Quadrant Circles, not Full Circle.

Will be work.

This ma be an obvious question but what are you trying to acomlish?

 

the code you referenced "G17 G03 X-35 Y-43 R.131" is for a circular move.  Are you trying to drill holes?

 

Without knowing what the control is you are just guessing on what the machine needs.  You must have knowledge of the machine requirements befor creating a post.

Re: Post Build: What should I put in my Post to generate a correct G code that performs holes? radiu

Hi,

 

Not Drill, im trying hole milling (throug) .26in

 

I think I'm doing the strategy the right way but ...

Re: Post Build: What should I put in my Post to generate a correct G code that performs holes? radiu

Thanks, I followed your advice to put in "circular record" "quadrant". One question, what should I put in IJK Definition?
-Vector - ArcStart to Center
-Vector - Arc Center to Start
-Unsigned Vector - Arc Start to Center
-Vector - Absolute Arc Center

Do you think that in this way, the strategy is starting where it ends?

I see that points 1 and 3, and 2 and 4 in each sequence are the same.
Besides X in N150 and N190 is the same.

I see everything well, what do you think?

Thank you

If you use R - you no need any IJK values.
