Not from a machine shop, but good nonetheless: My buddy, a mechanic, has this in his shop: Repairs $50/hour $60/hour if you bring the parts $100/hour if you worked on it first and... Flats fixed: $ If you watch: $$ If you help: $$$

Has anybody seen this in Lathe, or is it Mill only?

That has to be the funniest post I've read EVER I think I Dunno hangs out with "somebody" as in "somebody dropped this..." or "somebody didn't put that tool where it belongs..." or my favorite "somebody must've bumped the turret..." "Bumped," of course, can be used any time that the turret is not literally knocked out of the machine. That, I think, is "thumped."

As long as you don't try to replicate the horrid grey on grey screen on my Okuma OSP-U10M I'll be stoked we old-time AutoCAD guys dig white on black

I always program my spots .010-.020 shallow for that very reason! I love when one of the guys comes in saying "I don't know what you're doing but the program is doing something crazy" and I walk out to the machine and say "It might help if you touched the tool off..." In fairness, my butt has been saved more than once by a guy who looked closely before pushing the button TGIF

My Fadal experience is limited to their (I hope) low-end VMCs I guess there's nothing wrong with them, except for the fact that I can make a better part on a Bridgeport

Oh no! Something I might actually have to like about a Fadal

Hey James; you're not alone! I'm sure most of us have a day shift/night shift story or too to tell: A couple of years ago we had a job that was really hot (which one isn't) that the night shift set up and the guy edited the program to slow down one tool because he "thought the RPM was too high" and he didn't like it. As a result the night shift ran about 6 parts all night. When the day shift came in, we changed the job back to what it should've been and ran about 30 parts; problem solved, right? NO! The night shift guy CHANGED IT BACK and ran another 6 or 8 parts!!! We almost had a fistfight between the night and day CNC milling foremen the next day. Every shop has (at least) one guy who always knows better

Is there any control that allows you to turn comp on in an arc move? Thom; is there any way to add a straight "lead in" move to your path, this should eliminate your problem I think [ 07-11-2002, 12:48 PM: Message edited by: chris m ]

Any time

What do you mean I can't machine that 4" deep 1" wide pocket in one pass...?

I agree that my metric 390s cut small, that's why I still wonder about them secretly wishing to be inch cutters, I know my 32MM cuts right on 1.250" Slightly off the topic: I have found that Sandvik's quality as of late has been not so hot; has anyone else felt this way?

Derrickg I run an 1-1/2" 4 flute endmill style 390 cutter in 6061-T6 at 2000 SFM (limited by machine horsepower) with a 3/16" axial DOC and 1" radial DOC in a little Matsuura RAII with a .030 IPR feed and the cutter loves it, if only my machine had some more horses... With the Sandvik 3040 grade insert, these cutters run great in iron (350 SFM dry in heat-treated ductile iron) for us us well. if you're going to run one, have the Sandvik guy come in and work your application with you, they are usually pretty knowledgable and if they smoke it, you don't own it!

Are you sure your 16mm isn't really 5/8"? It sure sounds like it is... If you guys would just get on board with us in the real (inch) world, there would be no problems... C

1) Inspection would fail it, but I know its OK 2) Those tolerances on the print aren't what they REALLY need 3) We'll hang on to that one until they really need it, that way they won't check it 4) Those are lightening holes

Did I misinterpret that "lawnmower and a 340" crack to be an analogy to the "why doesn't wire work like mill?" question or did my man above miss that one? By the way; why would you want anything for a Dodge?

James Are you talking twin-spindle, twin-turret or single-spindle, twin turret? I primarily turn the first side of a part in the "main" spindle (bar-fed collet chuck (Production Dynamics chucks rock, by the way)) then do a cutoff/pickoff routine and turn the second side on the right "sub" spindle with little or no "assist turning." I'm not sure that I'm turning like you are; would your method would work for this? Inquiring minds want to know Thanks C

A couple of words on libraries 1) Sandvik's Coroguide CD has milling and turning tools available as 2D .dxf files; I don't know if that helps you guys or not... 2) ... the drawings in the libraries can be pretty terrible: inserts in wrong location, incorrectly drawn, wrong "f" dimensions, a million duplicate entities, etc. I use MC primarily for turning and we end up re-creating most of the tools using the dimensions out of the book because it is usually faster than trying to fix the heinous Sandvik drawings; not a huge time saver C

I don't know solids, but in 2D I believe this is the way to go: ScreenConfigureCAD SettingsGlobals Then adjust the Scale to 2.0 I believe this will help; let me know if I misunderstood C

Thanks James, I will check it out! C

I don't use an extended length or a metric shank cutter, so I guess that would explain why my 390s have weldon shanks (happily); I'll have to remember that in the future to avoid loud bangs in the shop. Corogrip chucks are very nice, but also very$$$$$$$$$$$$$$$

This may be a silly question, but here goes; why would you want to draw something 1/2 scale?

Where'd you get one without a Weldon shank?!?! That, i agree, would be scary

Jeez, sounds like I should move to California Any of you guys know about any good schooling going on in the East? I know my reseller has training, but I have a feeling that I could use my company's tuition reimbursement policy to get in a class or two at a local learning institution while "times are too tight for training." Thanks C
