Haas Lathe sub spindle orient M119 R...

[peter]

would it be possible to have a predefined R-value for the sub spindle output. something like an R-offset value from the machine orientation and the desired orientation of the machining face.

currently G14 M19 R0

desired G14 M19 R (value entered in the post dialogue box )

Hi @peter ,

I checked with Haas ST-30Y, if I set Got secondary spindle as Positioning only as shown in screenshot below:

I am getting the following output:

G14 and G0 M19 R0 will be in different line.

Does your current post output in G14 M19 R0? if yes could you share the post that you are using.

[peter]

Yes, I believe both machines share the same post. When I checked I saw that my latest post was used on several different haas lathe including the st20y. I am not near my computer and cannot tell you the version number but my output is the same as the one you described

[peter]

Hi AJU,

I have the same output as you, see below

I gladly send you my post, but it is the one available from fusion for ST20Y version 44114 which i believe is the same post you are using for the ST30Y. i never modified anything and as you pointed out, i also select, positioning only.

I am not sure what your issue is with the post, but my issue is the radial output being an R-value selected by fusion, whilst i don't have an offset option for that spindle. lacking the offset, i was hoping to have my post modified to give me the option to enter a value to be added to the R-output as way of compensation.

Hi @peter ,

I hope you're doing well. According to your need, you'll need to make 4 key modifications to your post. I'll walk you through them.

Modification 1:

First, you want to add the following code in the designated area (please refer to the attached screenshot for the precise location):

rValueOffset: {
  title: "R-Value Offset",
  description: "Compensate R Value to Secondary Spindle",
  group: "configuration",
  type: "real",
  range: [-360, 360],
  value: 0,
  scope: "post"
},

Modification 2:

Next, you'll want to add another block of code (again, refer to the second screenshot for the exact location):

var rOffsetFormat = createFormat({ decimals: 3, type: FORMAT_REAL, scale: DEG });
var rOffsetOutput = createOutputVariable(rOffsetFormat);

Modification 3:

You'll need to replace an existing block of code with the following one (please see the third screenshot for the correct location):

//Condition to add R Offset Value
if (getProperty("gotSecondarySpindle") == "true") {
  var newRValue
  newRValue = Number(rOffsetOutput.format(abc.z)) + Number(getProperty("rValueOffset"))
  // Normalize newRValue to be within 0-360
  if (newRValue < 0) {
    newRValue += 360;
  } else if (newRValue >= 360) {
    newRValue -= 360;
  }
  skipBlock = _skipBlock;
  writeBlock(
    gMotionModal.format(0),
    conditional(machineConfiguration.isMachineCoordinate(0), aOutput.format(abc.x)),
    conditional(machineConfiguration.isMachineCoordinate(1), bOutput.format(getB(abc, currentSection))),
    conditional(machineConfiguration.isMachineCoordinate(2), "M19 R" + zFormat.format(newRValue))
  );
} else {
  skipBlock = _skipBlock;
  writeBlock(
    gMotionModal.format(0),
    conditional(machineConfiguration.isMachineCoordinate(0), aOutput.format(abc.x)),
    conditional(machineConfiguration.isMachineCoordinate(1), bOutput.format(getB(abc, currentSection))),
    conditional(machineConfiguration.isMachineCoordinate(2), cOutput.format(abc.z)))
}

 Modification 4:

Finally, add this last block of code into your post (check the fourth screenshot for the specific location):

  rOffsetFormat.setScale(-DEG)
  rOffsetOutput.setCyclicLimit(360);
  rOffsetOutput.setCyclicSign(1);
  rOffsetOutput.setFormat(rOffsetFormat)

After you've made these modifications, select the post again. You should now be able to see a new Variable called "R Offset value". Any values added in the field will be included in the output as shown in the final screenshot.

I hope this helps! Please do not hesitate to reach out if you have any more questions or face any difficulties.

Hi AJU,

I made all the changes you suggested. Thank you for all your efforts.

there is one small problem,

your changes impacted the main spindle also.

the post properties was set to " got secondary spindle"   "positioning only"

if i set it to contouring i get a C-output for both main and sub. which does not work

before post changes: (that is correct for main spindle)

M15

G0 C0.

M14

after changes 

M15

G0 M19 R0

M14

when i enter an offset value, it applied this to the main spindle also.

Hi @peter ,

To address the issue, you can modify the codes in the post as shown below:

Original:

//Condition to add R Offset Value
if (getProperty("gotSecondarySpindle") == "true") {
  var newRValue
  newRValue = Number(rOffsetOutput.format(abc.z)) + Number(getProperty("rValueOffset"))
  // Normalize newRValue to be within 0-360

Modified:

  //Condition to add R Offset Value
  if (getProperty("gotSecondarySpindle") == "true" && currentSection.spindle == SPINDLE_SECONDARY) {
    var newRValue
    newRValue = Number(rOffsetOutput.format(abc.z)) + Number(getProperty("rValueOffset"))
    // Normalize newRValue to be within 0-360

This modification should resolve your issue, and the R Offset Value will only be added when the got Secondary Spindle property is set to "Positioning Only" and if the Secondary Spindle is selected.

I hope this helps!

Hi AJU,

Thank you very much, this works great now

[peter]

I would like to enter an R-Value containing a decimal place. right now i am limited to whole numbers.

how can the post be changed to allow that ? the lines in the post are:

var rOffsetFormat = createFormat({ decimals: 3, type: FORMAT_REAL, scale: DEG });
var rOffsetOutput = createOutputVariable(rOffsetFormat);

Thanks

Peter

Hi @peter ,

You can change the type of rOffsetValue definition as shown below:

Original:

  rValueOffset: {
    title: "R-Value Offset",
    description: "Compensate R Value to Secondary Spindle",
    group: "configuration",
    type: "real",
    range: [-360, 360],
    value: 0,
    scope: "post"
  },
};

Modified:

  rValueOffset: {
    title: "R-Value Offset",
    description: "Compensate R Value to Secondary Spindle",
    group: "configuration",
    type: "number",
    range: [-360, 360],
    value: 0,
    scope: "post"
  },
};

Output will display as shown in the screenshot:

I hope this helps!

[peter]

Thank you AJU
