Add IJK Drilling Support to Posts

[Steinwerks]

I tried to get this adopted here: http://forums.autodesk.com/t5/hsm-post-processor-forum/add-ijk-support-for-g83-in-haas-milling-post/...

It's quite silly given how simple this code is I think. I have been using it in both our Haas and Fadal posts and it works quite well. Here are the sections that I have added if they are helpful.

Haas:

    case "chip-breaking":
      if (cycle.accumulatedDepth < cycle.depth) {
        expandCyclePoint(x, y, z);
      } else {
        writeBlock(
          gRetractModal.format(98), gAbsIncModal.format(90), gCycleModal.format(73),
          getCommonCycle(x, y, z, cycle.retract),
          //"Q" + xyzFormat.format(cycle.incrementalDepth),
	  (((cycle.incrementalDepthReduction > 0) ? "I" : "Q") + xyzFormat.format(cycle.incrementalDepth)),
	  conditional(cycle.incrementalDepthReduction > 0, "J" + xyzFormat.format(cycle.incrementalDepthReduction)),
	  conditional(cycle.incrementalDepthReduction > 0, "K" + xyzFormat.format(cycle.minimumIncrementalDepth)),
          conditional(P > 0, "P" + milliFormat.format(P)), // optional
          feedOutput.format(F)
        );
      }
      break;
    case "deep-drilling":
      writeBlock(
        gRetractModal.format(98), gAbsIncModal.format(90), gCycleModal.format(83),
        getCommonCycle(x, y, z, cycle.retract),
        (((cycle.incrementalDepthReduction > 0) ? "I" : "Q") + xyzFormat.format(cycle.incrementalDepth)),
	conditional(cycle.incrementalDepthReduction > 0, "J" + xyzFormat.format(cycle.incrementalDepthReduction)),
	conditional(cycle.incrementalDepthReduction > 0, "K" + xyzFormat.format(cycle.minimumIncrementalDepth)),
        conditional(P > 0, "P" + milliFormat.format(P)), // optional
        feedOutput.format(F)
      );
      break;

Fadal:

    case "chip-breaking":
      // cycle.accumulatedDepth is ignored
      if (dwell > 0) {
        expandCyclePoint(x, y, z);
      } else {
        writeBlock(
          gRetractModal.format(98), gAbsIncModal.format(90), gCycleModal.format(73),
          getCommonCycle(x, y, z, cycle.retract),
          //"Q" + xyzFormat.format(cycle.incrementalDepth),
          (((cycle.incrementalDepthReduction > 0) ? "I" : "Q") + xyzFormat.format(cycle.incrementalDepth)),
	  conditional(cycle.incrementalDepthReduction > 0, "J" + xyzFormat.format(cycle.incrementalDepthReduction)),
	  conditional(cycle.incrementalDepthReduction > 0, "K" + xyzFormat.format(cycle.minimumIncrementalDepth)),
          conditional(cycle.chipBreakDistance > 0, "P" + xyzFormat.format(cycle.chipBreakDistance)), //optional P value
          feedOutput.format(F)
        );
      }
      break;
    case "deep-drilling":
      if (dwell > 0) {
        expandCyclePoint(x, y, z);
      } else {
        writeBlock(
          gRetractModal.format(98), gAbsIncModal.format(90), gCycleModal.format(83),
          getCommonCycle(x, y, z, cycle.retract),
          (((cycle.incrementalDepthReduction > 0) ? "I" : "Q") + xyzFormat.format(cycle.incrementalDepth)),
	  conditional(cycle.incrementalDepthReduction > 0, "J" + xyzFormat.format(cycle.incrementalDepthReduction)),
	  conditional(cycle.incrementalDepthReduction > 0, "K" + xyzFormat.format(cycle.minimumIncrementalDepth)),
	  conditional(cycle.chipBreakDistance > 0, "P" + xyzFormat.format(cycle.chipBreakDistance)), //optional P value
          feedOutput.format(F)
        );
      }
      break;

I think it's silly not to support peck reduction, frankly.

Tried to post a program for the Fadal today and realized that chipBreakDistance is only available in the "Chip Breaking - Partial Retract" toolpath so I had to take out this line under Deep-drilling:

conditional(cycle.chipBreakDistance > 0, "P" + xyzFormat.format(cycle.chipBreakDistance)), //optional P value

It is an option in the Fadal control though for a G83 cycle.

Voted up, even though I stole your code awhile back when you first posted to roll it into my Haas post!

It has worked great so far for me.  

This is definitely a valuable addition to the stock post.  Especially when using some parabolic drills where you can hit it with 3xDia on the first peck, then reduce to 1xD for the remainder.
