Feature request: Better options to reduce chip accumulation during drill operations

[kcameronLCNFA]

I spent a good bit of time today drilling some deep holes in PEEK plastic today.  It a thermoplastic that creates a stringy messy birds nest of chip accumulation around the drill.  For the life of me I could not get it to break a chip. 

Haas has an optional variable “E” in the g83 peck drilling cycle that will reverse the drill after the cycle is complete.  E5000 should spin the drill in reverse to 5000 rpm.  Adding this to the options in the drill cycles would remove stringy chip accumulation with many materials, but with deep holes in peek I’m not sure it would be enough.  I ended up pecking to try to reduce the chip accumulation.  It helped a bit. I ended up stringing together multiple peck drilling operations with a full retract on Z then stop the spindle and a M00 mandatory stop to give me chance to manually remove chips from the drill bit.  Automating process like this would be incredibly helpful.  Also giving greater control with G83 peck drilling cycle on how high the peck retraction R value is above the part would be great. Such that it start drilling at the top of the part, but the drill would retract 1” above the part to clear the chips the rapid back down to where the drill left off in the cycle.  If it could optionally spin in reverse when it reaches the retract height that would be fantastic.

Try 150sfm, F10., Q30%, M8 R.250.

"greater control with G83 peck drilling cycle on how high the peck retraction R value is above the part would be great."
That's literally what your "Feed Height" does!


If you want a massive R plane but for it to start drilling at the face, do something like this if you had 1" R value and a Q of .06

Yes, but it feeds from the r plane.  I’d like it to rapid from the r plane to the top height.  This would be crazy slow.  I can go in a manually edit the g-code, but if I can do that, then fusion360 can do it too.  Between g99 g98 and the r plane height, additional options are available.  I could even go into the Haas machine settings and

If you do what I say, it would take 6 seconds to go from your R plane to the first peck. How many holes do you have to do, and how many minutes will you spend trying to save seconds?

Properly selected modes will allow you to get rid of chips. And the reverse of rotation was not necessarily high at all
