VM-20 drills holes twice w/cam programming

[kmpstr]

Hope someone has an idea about this.

When we program a part from Featurecam, and post it, the code looks good, but the VM-20 (VM-2) drills (and taps) every hole twice. The code has a single G83 (or whichever drill cylcle), so we figure at this point it must be some setting in the machine.

thanks

It might be an idea to post a section of the code so that the problem can be seen. I had a similar problem on a Cinncinati, it wasn't putting a g0 after the canned cycle to cancel it so the machine drilled the last hole twice. It could possibly be a problem with your post processor. Try posting the same question in the featurecam section.

Here is the code for two of the holes consecutive

/'HOLE2'
/'TOOL NUMBER:2'
/' SPINDLE RPM:2510'
N485M5
N490G0X0.Y0.T2D0.0M6
N495F16.5S2510M3
N500X1.0Y-4.0
N505Z0.025
N510G83Z1.2814Z0.5375Z0.2188F16.5
N515X1.0
N520G80
N525Z1.0
N530Y-2.5Z0.025
N535G83Z1.2814Z0.5375Z0.2188F16.5
N540X1.0
N545G80
N550Z1.0


I plan on hitting the Featurecam section, just tried here first

thanks

Lines N515 and N540 are your culprit. I recall (a few years ago now) that I had the same problem with my ultimax II post in featurecam.

If you control-click on the status bar and select xbuild debug options and select everything it will show you which section of the post is generating that redundant line. It will either be the deep hole format or the cycle cancel format I'd guess.

Edit:

Just had a quick look and it seems that you are using the HURCO.CNC post processor. It posts that redundant move in the deep hole format (and possibly others). If your machine has the Winmax control, you should probably be using the HURCO WINMAX.CNC post processor instead. If you want to keep using that post (if everything else works fine it's probably a good idea) just open it up in xbuild and delete the {N<SEQ>}X<X-COORD><EOB> line in the deep hole format.

O.K, that is what I missed, I'll try that tomorrow. We don't have a Hurco Winmax post listed, so that is why we went with this.

thanks again
