OKK HMC rotary axis 1 degree increments

Anonymous — Tue, 31 Oct 2017 07:21:43 GMT

Hi. I am now working on getting my post working with the OKK HMC.

I have everything working, but the OKK rotary table will only increment in full one degree movements.

basically i want the post to error out if a B axis move is not in full degrees.

It seems like the following code may be what im looking for, but it looks like it may just round the B figure? And i am also not sure how to activate it.

Any help would be appreciated.

function getWorkPlaneMachineABC(workPlane) {
  var W = workPlane; // map to global frame

  var abc = machineConfiguration.getABC(W);
  if (closestABC) {
    if (currentMachineABC) {
      abc = machineConfiguration.remapToABC(abc, currentMachineABC);
    } else {
      abc = machineConfiguration.getPreferredABC(abc);
    }
  } else {
    abc = machineConfiguration.getPreferredABC(abc);
  }
  
  try {
    abc = machineConfiguration.remapABC(abc);
    currentMachineABC = abc;
  } catch (e) {
    error(
      localize("Machine angles not supported") + ":"
      + conditional(machineConfiguration.isMachineCoordinate(0), " A" + abcFormat.format(abc.x))
      + conditional(machineConfiguration.isMachineCoordinate(1), " B" + abcFormat.format(abc.y))
      + conditional(machineConfiguration.isMachineCoordinate(2), " C" + abcFormat.format(abc.z))
    );
  }
  
  var direction = machineConfiguration.getDirection(abc);
  if (!isSameDirection(direction, W.forward)) {
    error(localize("Orientation not supported."));
  }
  
  if (!machineConfiguration.isABCSupported(abc)) {
    error(
      localize("Work plane is not supported") + ":"
      + conditional(machineConfiguration.isMachineCoordinate(0), " A" + abcFormat.format(abc.x))
      + conditional(machineConfiguration.isMachineCoordinate(1), " B" + abcFormat.format(abc.y))
      + conditional(machineConfiguration.isMachineCoordinate(2), " C" + abcFormat.format(abc.z))
    );
  }

  var tcp = false;
  if (tcp) {
    setRotation(W); // TCP mode
  } else {
    var O = machineConfiguration.getOrientation(abc);
    var R = machineConfiguration.getRemainingOrientation(abc, W);
    setRotation(R);
  }
  
  return abc;
}

The DMG Mori NHX post processor has logic to limit the B-axis move in whole degrees. You can use this post as a reference to modify your post. Look for the string 'gotContinuousBAxis' throughout the post and use the logic that applies to !getContinuousBAxis in your post.

In the onOpen function. Since you do not need it as an option you can create abcFormat and bOuput at the top of the program where they normally are.

      bAxis = createAxis({coordinate:1, table:true, axis:[0, (properties.makeBAxisOtherWay ? -1 : 1) * -1, 0], cyclic:true, range:[0, 360]});
      abcFormat = createFormat({decimals:0, forceDecimal:true, scale:DEG});
      bOutput = createVariable({prefix:"B"}, abcFormat);

In the getWorkPlaneMachineABC function. You can change '!properties.gotContinuousBAxis' to 'true'.

 var abcTest = new Vector(abc.x, abc.y, abc.z); // affects output if not copied to new vector
  if (!properties.gotContinuousBAxis) {
    abcTest.setX(toRad(abcFormat.getResultingValue(abc.x)));
    abcTest.setY(toRad(abcFormat.getResultingValue(abc.y)));
    abcTest.setZ(toRad(abcFormat.getResultingValue(abc.z)));
  }
  var direction = machineConfiguration.getDirection(abcTest);
  if (!isSameDirection(direction, W.forward)) {
    error(localize("Orientation not supported."));
  }
