Okuma coolant off / dwell

[Anonymous]

Hi everyone.

I'm looking for help modifying my post. Currently, at the end of an operation, the spindle turns off, then it rapids up, then the coolant turns off. I would like to change the order of things so that first the coolant turns off, then add a dwell (2 seconds?) for the tool to spin off excess coolant, then the rapid and everything else as it is now.

I have rudimentary coding skills so i was able to figure out how to change all the m06 with g116 for the okuma, and I was able to make the end of the program do a G30 Px before the M02. The order of operations mentioned above is a little outside my wheelhouse. Any ideas?? thanks

Hello Chris,

This is a pretty simple change.  I am guessing that you are using the stock Okuma post, so the changes I am suggesting are based on this post.

First find this code in the onSection function.

  if (insertToolCall || newWorkOffset || newWorkPlane) {
    // stop spindle before retract during tool change
    if (insertToolCall && !isFirstSection()) {
      onCommand(COMMAND_STOP_SPINDLE);
    }
    // retract to safe plane
    writeRetract(Z);
    if (newWorkPlane) {
      setWorkPlane(new Vector(0, 0, 0)); // reset working plane
    }
  }

And modify it to look like this ...

  if (insertToolCall || newWorkOffset || newWorkPlane) {
    setCoolant(COOLANT_OFF);  // add these 2 lines
    onDwell(2);

    // retract to safe plane (move these 2 lines up)
    writeRetract(Z);

    // stop spindle before retract during tool change
    if (insertToolCall && !isFirstSection()) {
      onCommand(COMMAND_STOP_SPINDLE);
    }
    if (newWorkPlane) {
      setWorkPlane(new Vector(0, 0, 0)); // reset working plane
    }
  }

Now comment out the coolant off code further down the function.

  if (insertToolCall) {
    forceWorkPlane();
    // setCoolant(COOLANT_OFF); // comment out this line
  
    if (!isFirstSection() && properties.optionalStop) {
      onCommand(COMMAND_OPTIONAL_STOP);
    }
