convert g92 to g76

[simonswb6]

The current post processor i have is for a funuc control and for a threading cycle, it using a g92.  My machine (mazak) does not use g92, but instead uses a g76.

i have the post process outputing the code correctly, however it keeps repeating.   its calling the onCyclePoint until it reaches the min x value.  anyway to stop this?  i just need this line once...

N23 G76 X2.617 Z-0.435 K0.04 D4 F15.999999999999998

N24 G76 X2.609 Z-0.435 K0.04 D4 F15.999999999999998

N25 G76 X2.601 Z-0.435 K0.04 D4 F15.999999999999998

N26 G76 X2.593 Z-0.435 K0.04 D4 F15.999999999999998

switch (cycleType) 

  {

  case "thread-turning":

    var minDepthCut = Math.ceil(getParameter("operation:threadDepth")*1000/(getParameter("operation:numberOfStepdowns")));   

    var threadPass = getParameter("operation:threadDepth") / 100;

    var inverted = (toolingData.toolPost == REAR) ? 1 : -1;

    //var r = -cycle.incrementalX * inverted; // positive if taper goes down - delta radius

    var threadsPerInch = 1.0/cycle.pitch; // per mm for metric

    //var f = 1/threadsPerInch;

    xOutput.reset(); // at least one axis is required

    zOutput.reset();

    writeBlock(

      gFormat.format(76),

      xOutput.format(x),

       zOutput.format(z),

      "K" + getParameter("operation:threadDepth"),

      "D" + minDepthCut,

      "F" + getParameter("operation:threadPitch")

      );

     // break;

     //debug("The value of x is " + x); 

      return;

  }

I think you will get more traction with this if you post in the "Fusion manufacture" section. They were very helpful in finding a fix for the Creative Evolution controller in an older Haas machine we purchased.

When you changed it from 92 to 76 did you just change the number?

Have you looked at the Mazak posts here  https://cam.autodesk.com/hsmposts? what you will find using Mazak as the search

I posted this in the wrong area..

i was able to find a solution my self...

>what you will find using Mazak

i found the mazak post to not be suitable for my needs.  i started with a Fanuc post and have been modifying as needed.

Hi @simonswb6 ,

Download the latest version of Fanuc turning post from post library and search useSimpleThread and set it false

useSimpleThread: false // outputs a G92 threading cycle, false outputs a G76 (standard) threading cycle

Save the post and test it.

Thanks,
