    Mostly done in extensive upgrade in our use of Mastercam

    You should check out Prototek's Strategy Manager; looks like this is very similar: http://forum.mastercam.com/Topic32506.aspx

    Dynamic Milling VS Machine Accuracy....over time

    Using dynamic paths in Ti and 17-4 for three and a half years on a 2015 Haas. I false brinelled the y axis thrust bearing by peeling a .020" wide slot with a .010" endmill about 3/4" long, 12 slots indexed around a part, 12 parts. Got that replaced and learned my lesson. Since then I've made dozens of those parts with no damage by peeling about 1/4" and making a 3" diagonal move and back, then continuing. Machine still holds a tenth all day if I hold up my end.

    Form tap to fix anodized undersized holes in Ti?

    When I say "in", I mean I'm going to make the go gauge bigger and the no-go gauge smaller, to tighten the tolerance on both sides before plating. That way I'm covered whether the holes grow, shrink, or stay the same. Holes are thru. Thanks

    Form tap to fix anodized undersized holes in Ti?

    I've made several batches of these plates before, and they've come out good. I'm thinking of getting a pre-plate gauge, but the plater claims zero dimensional change. I don't believe them. I'm thinking of bringing the pitch diameter tolerance in .0005" on each side for pre-plate to allow for some random change at the plater for future batches. Yes, the screw goes in in the field. Thanks
  5. I asked this on PM but figured I'd ask here too. I have some fairly high dollar (for us) Ti6Al4V-ELI parts that came back from hard-coat anodize with some threadmilled 6-32 holes ever so slightly undersized such that the go gauge will almost but not quite pass through. Holes are through a .075" thick wall. Is it safe to use a greased form tap to resize them? Also, my plater claims that the anodization doesn't change the dimensions at all. Is that bull? I need to now if I need a pre-plate thread gauge to ensure this doesn't recur. Maybe I should get a go gauge that's a few tenths big, and use the standard no-go? Thanks!

    AB Shear hog - shop staple, or obsolete relic?

    Had one doing great about five years ago, don't cut much aluminum anymore.

    Compensation Poll - Take the poll

    If you go to a different diameter endmill then you'll need to change speeds, feeds, stepovers, stepdowns, etc., and you won't know for sure if it will gouge or crash until you've re-verified with the new cutter. May as well change it in CAM and re-post. If it's a regrind only a few thou different you can probably get away with it and just comp it in, but any cut not using comp will leave extra stock, and that may mess up your finish passes. This becomes significant when your 5/8" endmill measures .575", in addition to the fact that now you're using a weaker and more flexible cutter than what you programmed for. Using a different cutter than what's on the setup sheet is a big NO in my book.

    Stock Models

    You have always been able to do this. Take a copy of your part model and a gnomon at the WCS for your first operation, rotate and translate them both together until the part is positioned for your next operation, and use the gnomon to define a new plane. Then make a new copy of your stock model, referencing no operations, and set it to use the new plane. I do this frequently in X9.

    Solidworks PDM for CAM files?

    My company is about to implement Solidworks PDM for our CAD files, and they're talking about putting my Mastercam, NC, and setup sheet files in there too. My gut reaction is that this would add overhead without any significant advantages, especially since I'm the only programmer, and presently the only setup person. Has anyone here gone down that road, that might share some experience? Thanks

    Haas question

    You mean this? https://www.haascnc.com/service/codes-settings.type=setting.machine=mill.value=S36.html It doesn't lock restarting in the middle, it just makes the machine scan up to the restart point.

    Is there a way around Solidworks and Mastercam

    I guess I'm a bit spoiled; I have Solidworks on my Mastercam computer, but I'm using X9, so I take the native SW part, save as X_B to bring it into Mastercam, and then I have the best of both worlds.

    Haas question

    That sounds like a good idea, and you don't need Haas to do it, you can do it yourself. There's a parameter to allow editing of 9000 programs, I think setting #23. Flip it back off when you're done. Either that or kick the operator out and lock the shop door. Just had another thought; you could have a variable that gets updated as the program progresses (set to a certain value at the end of each tool or cut), and have each section check that it has the correct value before beginning; error out if it doesn't. Not entirely idiot proof, but it could help.
