Haas G81 Drill Cycle - Reverse and clean drill (or reamer)

[ed]

Would love to see support for this or the equivalent in Fusion

After the drill or reamer retracts, coolant on (spray not TSC) and spin backwards.

You can do this as a passthough note to add this to the code manually.

I could code the program without Fusion as well.  But the point of buying a CAM software package is to not need to do that.  It is a simple request to include support for this concept in a future release.

I assume you want to add an 'E' value to your G81 (and others?). This is possible to do in the post processor. Do you want it to happen on every G81 or is there some criteria?

I just ran into needing this real bad for a job and now that I know how simple it is, I would definitely see using it more often. I wouldn't want to mess with post processor; it needs to be as a checkable option, since 90% of the time I don't need it. And even within a specific program I may only need it for a specific drilling path. Every once in a while we're using tools or materials that string extremely badly on specific features and nest after even one hole. Currently all I can seem to do is manually go to the specific G81 cycle and manually add the E value to the ones that need it. But it would be nice if I could just check a box in the drill dialogue and then specify the RPM of the reverse spin. Especially if I could use it in combo with deep drilling or peck drilling that doesn't seem to use a canned drill cycle.

Those should be canned, unless you are using the old post that expands canned cycles.

Fusion (and likely the POST also) do not support the variable to back spin it
