Soooo..... make any chips yet? Mike

The NL does have G112 polar and the MPMaster post that we use handles angled drilling just fine. If you really want to just start making chips, contact inhouse and I know they have a dialed post for that machine and it should be pretty reasonable. Mike -

quote: I think Bobcad is about as good as MC lathe now. That says a lot. (I haven't used BC, but its what I heard Lets not get too crazy.... Like Ron has said a few times, you can get mc to work with mill turns but it requires so many tricks and workarounds that it is hardly worth it. Mike

Yes I am talking about a mill toolpath. Do a regular contour and under contour type, select ocillate. Mike

quote: There is no Mastercam toolpath that I am aware of that automatically gives you the kind of ramping you need, you really want to ramp up and down so you are moving the cut line back and forth over a range of cut depth. Contour oscillate toolpath should do the trick. Mike

Depending on how many pieces you already have, you might just want to start with solid stock. Best drill, speed, feed combo in the world won't last long in that situation. Mike

We had that problem on a machine here once and it ended up being that the encoder had loosened up. Mike

+1 to multiple reamers. Mike
-
If you are you mplmaster, set misc value 4 to 1. That will give you good G112 code and not a million little Xc moves that give you that faceted finish you don't want. Mike
-
Are you running it with G112 or just raw c/x output? Mike
-
+1 on the thread mill. For the same reasons as above and also you can just use cutter comp to "creep in" on you pitch diameter. Your gonna need a pretty mean spindle to rigid tap 3/4 npt in stainless. Go though just a couple of taps and you have the cost of a nice thread mill right there. Mike

Ill take a look. [email protected] Mike

quote: All I'm trying to get is how was this figure arrived at, and if 60 thou is ok, then is 50thou ok or no good? It depends on the pitch of the ball screws and the number of balls in the bearing. If you know that, it is very simple to calculate. Mike [ 01-05-2010, 06:25 PM: Message edited by: GoetzInd ]

Well asuming the machine has 10mm pitch ball screws, .018 of motion is about 16.5 deg. at the motor. I can see this not being enough travel for the ball bearings to overlap on each other, thus working the grease out of the area. Mike

BOBCAD can copy and paste between windows..... but thats about it. Mike

We have some rather large and complex PPS plastic parts coming up. I don't have much experience with this stuff (other than one small turning part) and it is really pricy so I was wondering of any tips or suggestions anyone might have. Turning, milling, tapping. Thanks. Mike

You have a sub spindle. Why not chuck up a center and use it? I know its a pain in the a$$ but Proper Planning Prevents xxxx Poor Performance. Mike

Sounds like a plan quote: Then get the yellow books out... I hate those yellow books. Mike

quote: The machine doesn't happen to be a Doosan Puma by any chance does it? Yep. The funny thing is our other doosan machines do not have this problem. Mike

I have been programming some X-Caxis paths on a new machine we have because it does not have enough Y axis travel to reach all the way around the profile. Control is a 18i and I'm using G12.1 cord. conversion and the machine is cutting smoothing but the profile accuracy isnt even close. Off maybe .020 in some areas. My question: is there a parameter that controls the accuracy of the the G12.1 function? I don't think I am feeding too fast. Only 50ipm. And I don't have this problem on other machines. Any thoughts about C axis profiling in general? Thanks, Mike

Keep in mind you will not be getting a true form if your using a t slot cutter since it is ramping. Mike
-
Newer haases have real spindle orientation. Look at ph horn for tooling. I would only be doing aluminum with LIGHT cuts though. Remember, when that spindle isnt spinning it is very easy to damage the bearings. Mike
