Siemens Turning 802d omit G97 and Change G18 to G17 for Drilling

paul.slaterMZZFE — Sun, 03 Nov 2019 16:38:40 GMT

Could someone help please? i am using the Generic Seiemens post for turning and i need to Omit the G97 (line N19)and change the G18 (line N10) to G17 for drilling (which will need to be switched back to G18 for normal turning. below is a sample of a simple drill code:

; %_N_1001_MPF
N10 G90 G94 G18
N11 G71
N12 LIMS=4000
N13 T0
N14 G53 G0 X700.

; Drill2
N15 T6 D1
N16 G54
N17 M8
N18 G94
N19 G97 S2890 M3
N20 G0 X0. Z15
N21 F231.498
N22 CYCLE82(5, 0, 5, -25, )
N23 X0.
N24 G0 Z15

N25 M9
N26 T0
N27 G53 X700.
N28 M30

can someone help please? Regards Paul.

@paul.slaterMZZFE

Do you want to omit the G97 all the time or on any drilling cycle only?

And if you want to G17 for any drilling cycle only is ok to call it like this

N15 T6 D1
N16 G54
N17 M8
N18 G94
N19 G97 S2890 M3
N20 G17
N21 G0 X0. Z15
N22 F231.498
N23 CYCLE82(5, 0, 5, -25, )
N23 X0.
N24 G18
N25 G0 Z15
N26 M9

Because if try to post process multiple operation at once then the change in top may not work as you expected

Boopathi -thank you for your response. I do need to have other turning operations also in the programme.

I also need to omit the G97 on line N19. I am not sure why this is not standard in the Generic post as this seems to be standard across all Siemens controls? Thank you Paul.

paul.slaterMZZFE — Mon, 04 Nov 2019 08:33:59 GMT

Boopathi -sorry, I misread your question. Delete G97 only for the drilling cycles please. I did try to use some code that was on another forum post by AchimN that writes the Drill Cycle in G01 which would be OK for the small amount of drilling that i do, although I don't know what would happen to Tapping? it is as follows:

function onCyclePoint(x, y, z) { /////// Insert the 2 lines below here
expandCyclePoint(x, y, z);
return;

this worked but the G01 lines were output below the Cycle82 and i did not know how to suppress the outputting of the Cycle82 ?

thanks Paul.

Edit the post processor as mentioned below

go to this place by searching if (getspindle(true) you will see below set of codes

if (getSpindle(true) == SPINDLE_SECONDARY) {
    writeBlock(
      spindleMode,
      sOutput.format(_spindleSpeed),
      spindleDir
    );
}else{
        writeBlock(  
          spindleMode,
          sOutput.format(_spindleSpeed),
          spindleDir
        );
      }

add the below set of codes so the else portion

if(currentSection.hasAnyCycle()){

writeBlock(

//spindleMode,

sOutput.format(_spindleSpeed),

spindleDir

);

}else{

writeBlock(

spindleMode,

sOutput.format(_spindleSpeed),

spindleDir

);

}

final codes will be like this

 if (getSpindle(true) == SPINDLE_SECONDARY) {
    writeBlock(
      spindleMode,
      sOutput.format(_spindleSpeed),
      spindleDir
    );
}else{
if(currentSection.hasAnyCycle()){
        writeBlock(  
          //spindleMode,
          sOutput.format(_spindleSpeed),
          spindleDir
        );
      }else{
        writeBlock(  
          spindleMode,
          sOutput.format(_spindleSpeed),
          spindleDir
        );
      }
}

now save the post processor file.

if you want expanded cycle means then you have to tell the post processor to not post the cycle.

So how you want to post ? in cycle or in expanded format

Boothpati -thank you for the code. i am away from the office for a few days so cannot try. I will try over the weekend and let you know. The instructions are very clear! thanks Paul.

Boopathi -I think i have done something wrong I got an error.

Error: SyntaxError: missing } after function body
Error at line: 1459
Failed while processing global script.
###############################################################################

Error: Syntax error: Missing close for { at line 1258.

I have attached the PP would you be kind enough to point out where I made the mistake please?

@paul.slaterMZZFE

No worries you just missed a closing bracket } in a function

go and search for this line function onCommand

add a } above this line your final code will be like this

  }
  // wait for spindle here if required
  }
}

function onCommand(command) {

That's all you almost did a perfect job😉

paul.slaterMZZFE — Sun, 10 Nov 2019 09:51:26 GMT

Boopathi -thank you. All works perfect, except I have to change the G18 to G17 and then back again to G18 for other turning. Is this a big problem to solve? thank you Paul S.

Can you just attach a sample NC code here how you want or how you are manually changing the place so I can help you out

Re: Siemens Turning 802d omit G97 and Change G18 to G17 for Drilling

paul.slaterMZZFE — Sun, 10 Nov 2019 17:48:02 GMT

Boopathi -i have attached 2 files, one with single drilling operation and one with other turning operations. i wonder if it may be easier to output the plane that is relevant for every operation the same as happens with G54 for every new operation. Instead of having to keep swapping between G18 for normal turning and G17 for drilling/tapping?

Thank you and kind regards Paul.

paul.slaterMZZFE — Sun, 10 Nov 2019 17:50:47 GMT

Boopathi -One thing I forgot to mention is that because Siemens for whatever reason use G82 for drilling I have changed G82 in the post to G822 and G81 to G82. I am sure that is a cheap and dirty way to code it but it's the best i could think of and it works! thanks Paul

@paul.slaterMZZFE

Go and look for the code setCoolant(tool.coolant)

You get to see something like this

  gFeedModeModal.reset();
  if (currentSection.feedMode == FEED_PER_REVOLUTION) {
    writeBlock(getCode("FEED_MODE_UNIT_REV"));
  } else {
    writeBlock(getCode("FEED_MODE_UNIT_MIN"));
  }

Instead of the above code just copy and paste below

gFeedModeModal.reset();
  if (currentSection.feedMode == FEED_PER_REVOLUTION) {
    if (currentSection.hasAnyCycle()){
      writeBlock(getCode("FEED_MODE_UNIT_REV"),gFormat.format(17));
    }else{
      writeBlock(getCode("FEED_MODE_UNIT_REV"));
    }
  } else {
    if (currentSection.hasAnyCycle()){
      writeBlock(getCode("FEED_MODE_UNIT_MIN"),gFormat.format(17));
    }else{
      writeBlock(getCode("FEED_MODE_UNIT_MIN"));
    }
  }

Your final code will be like the above one.

and in the section end search for this line

function onSectionEnd() you get to see something like the below code

function onSectionEnd() {

  // cancel SFM mode to preserve spindle speed
  if (tool.getSpindleMode() == SPINDLE_CONSTANT_SURFACE_SPEED) {
    startSpindle(false, true, getFramePosition(currentSection.getFinalPosition()));
  }
  if (currentSection.partCatcher) {
    engagePartCatcher(false);
  }
  forceAny();
}

insert the code in red below and save the file

function onSectionEnd() {

  // cancel SFM mode to preserve spindle speed
  if (tool.getSpindleMode() == SPINDLE_CONSTANT_SURFACE_SPEED) {
    startSpindle(false, true, getFramePosition(currentSection.getFinalPosition()));
  }
if (currentSection.hasAnyCycle()){
  writeBlock(gFormat.format(18));
}
  if (currentSection.partCatcher) {
    engagePartCatcher(false);
  }
  forceAny();
}

This time it will work

Boopathi -thank you. It looks perfect in the NC file. I need to try on the machine but cannot do for a couple of days due to a new DMG Mori installation.

Thank you again for all your help and support, which has been invaluable. Kind regards Paul S.

Ps. I will click "Accept as solution" as soon as I have tried it.

Hi,

Is it available for download.

It will be very helpful to use it.

Please do the needful

Hi -you are welcome to a copy of my post processor. it works fine on a ROMI lathe with Siemens 802D control.

i had to change the extension to .txt to be able to attach it. please change back to .MPF

Kind regards Paul.

Hi,

I am curious if these fixes/changes make it into the generic Siemens posts eventually? Such as the Siemens Mill-Turn post here https://cam.autodesk.com/hsmposts

What causes the posts available here to get updated? If I make changes to these posts that are applicable to to the generic controller is there a way to submit those changes so they will be incorporated into the posts here?

I have a number of changes I have made (and been helped to make) and I have to add them by hand whenever a new post gets released (assuming I want to adopt it).

Thanks,

-Tom

Tomae -I am not sure what qualifies a modification to be considered incorporated into the generic posts, maybe it is the upvotes for the modification? I think the modifications that I have in my posts are only things that I feel should be in already Ie the G18, G17 issue as this theoretically, should be affecting every Siemens turning post that need to use drilling cycles. you have to bear in mind that it is what it says "Generic post" and Autodesk could not implement everyone's ideas on what they think should be a "standard post" or we would have a real mess in the field. regards Paul
