Output G10 L12... to Fanuc post

[Anonymous]

Hi!

I wanna have the bold part. 😄

Is there anybody out there thats already have this in a post?

If a tool uses a D value, I wanna have a G10 L12... line. The R value should be 0.0

Im using a generic fanuc post.

You can use one of the post processors very powerful features thats already inside most generic posts:

Heres a quick example.

look for this section of code:

    var tools = getToolTable();
    if (tools.getNumberOfTools() > 0) {
      for (var i = 0; i < tools.getNumberOfTools(); ++i) {
        var tool = tools.getTool(i);
        var comment = "T" + toolFormat.format(tool.number) + " " +
          "D=" + xyzFormat.format(tool.diameter) + " " +
          localize("CR") + "=" + xyzFormat.format(tool.cornerRadius);
        if ((tool.taperAngle > 0) && (tool.taperAngle < Math.PI)) {
          comment += " " + localize("TAPER") + "=" + taperFormat.format(tool.taperAngle) + localize("deg");
        }
        if (zRanges[tool.number]) {
          comment += " - " + localize("ZMIN") + "=" + xyzFormat.format(zRanges[tool.number].getMinimum());
        }
        comment += " - " + getToolTypeName(tool.type);
        writeComment(comment);
        if (tool.type == 5) {
          writeBlock("G10 L12 P"+ tool.number, "R" + xyzFormat.format(tool.diameter), "(T"+ tool.number, tool.description +")");
        }
      }
    }

tools = getToolTable(); looks through all the sections and retreives the data for every tool

there is a "for" loop that increments through the tools and stores that single tools data into an array called "tool"

if you use the post processor called dump.cps, you can see all the data that is stored for every tool. I had to use a formating function to reduce the number of trailing zeros in the tool diameter

Hi!

I missed your reply. 

This is what I was looking for! A little tweaking and its gonna be perfect. 

Big thanks!

Gonna bump this old thread. 🙂

The solution kinda works. If the tool.type is 5 (endmill?) and uses a wear comp.

If its not using a compensation type it should not be showing up in the gcode.

If the tool type is something else like a chamfer mill (tool.type 13?) and uses a compensation type. Its not showing up in the post.

How do i get this code to work?

If a tool uses a compensation type Wear. I want it to output it to the gcode. And only then.

     if (tools.getNumberOfTools() > 0) {
      for (var i = 0; i < tools.getNumberOfTools(); ++i) {
        var tool = tools.getTool(i);
		if (onParameter('operation:compensationType') == (wear)) {
		//if (tool.type == 5) {
          writeBlock("G90 G10 L12 P"+ tool.number, "R0.0", "(T"+ tool.number, tool.description +")");
        }
      }
    }

This is obviously not the correct way to get it to work. 😉

@skidsolo maybe you can push me in the right direction. Is something like this even possible. Or does it take a lot of modifying of the post?

[Laurens-3DTechDraw]

Post your program with the dump.cps post processor it will help you locate the name of the parameter you are looking for. And also what value you are checking for.

[Anonymous]

I suppose its this:
onParameter('operation:compensationType', 'wear')

Bur I cant get it to work in the post.

if (onParameter('operation:compensationType') == (wear))
this aint right. How should it look? 🙂

[Laurens-3DTechDraw]

First a different question,

what if a tool is used with and without compensation turned on?

From there on you are looking for an operation parameter but you aren't checking for it during the operation. That's why it doesn't work.

So you first need to tell it in which section it has to check for that parameter.

[makko74]

the right syntax should be:

if ( hasParameter( "operation:compensationType" ) && ( getParameter( "operation:compensationType" ) == "wear" ) )

Thanks for the help.

Im almost getting it to work now. 🙂

if (tools.getNumberOfTools() > 0) {
      for (var i = 0; i < tools.getNumberOfTools(); ++i) {
        var tool = tools.getTool(i);
	 if (hasGlobalParameter("operation:compensationType") == (getGlobalParameter("operation:compensationType") == "wear"));{
          writeBlock("G90 G10 L12 P"+ tool.number, "R0.0", "(T"+ tool.number, tool.description +")");
        }
      }
  }

This works with a tool using a operation:compensationType wear offset parameter. And when a tool has that parameter "operation:compensationType" in the dump.
But when its a tool  without  the operation:compensationType parameter like a drill or facemill its error out.

How do i put in a if else statement for the tools not having a operation:compensationType parameter?

And why should it be hasGlobalParameter and not just hasParameter?

[makko74]

Excuse me, my mistake, was thinking the code is from onSection, I supposes your code snippet stands in onOpen, there you must use hasGlobalParameter but it will not work as well as you want.

getGlobalParameter used in onOpen will return only the value from the first operation where this parameter ( compensationType ) will be set.

means: if your e.g. first operation use as compensation-type control then your code will not work.

You must rethink your code, like Laurens said.

Yes the code is in onOpen.

Thanks for the explanation.

Well im gonna try out the w3schools now. 🙂
