Hi Ken, Do you use the VNMG holder for that insert (vngp-330)? Thanks

Wow BOBCAD has come a long way! ;D~ Thanks for sharing Ron!!!

Jeff, 4500 rpm max. I can not use the tail stock. I tried the following inserts: VNMG-331, 1/64 tip rad grade C5, and VNMG 331 1/64 tip rad grade WP25CT. I also tried a positive Sandvik tool 55 degree insert TR-DC1304-F. I have tried various feed rates and depth of cuts. The best finish was 1000rpm and 0.002"/rev. I also tried cooltool 2 to see if that helped and there was no change. It is chattering on the end if I go to fast and will not cut straight. Thanks for any advice.

Hi, Got a small job machining some 1018 CRS. It is 7/8 dia and I have to turn about 3.5" down to .6255. I am roughing it first and finishing with a VNMG tool. The finish is not great. Is there something better? Sharper insert? Any suggestions would be welcome! Thank you in advance!

Okuma all the way, not even in the same league in my opinion.

Hi. I need a recommendation for a 9/16 drill bit. I have to do a couple of lathe jobs that require this drill, some Aluminum and some Brass. I need to drill about 3" deep with coolant through. I would prefer an indexable. Thank you in advance!

Thanks guys! Big thanks to Jeremy at www.dbssolutionsllc.com and Thee Circle!

Hi Ron, Yes I have a C-Axis DMG CTX 310 Eco (piece of $hit...another story)! Yes we have Mill ability on our seats of Mastercam. Colin, I tried transforming but it is not verifying correctly. See the screen shot. Thank you

I figured the solids question out! Now how to program it!

The file would not attach so I uploaded it to the FTP, it is in the X5 files folder called FUELKNOB.mcx-5 Here is a screen shot.

Hi, I have this part partly drawn in MC design. It is 1 1/4" brass and I need to cut 60 grooves across the OD (6 degrees apart). In Mastercam Lathe how can I program this? I was going to use a center drill to cut the groove. For the design solid is there a way to rotate the groove without rotating the base chains and sweep cutting each one? Thanks in advance!

Here are the instructions. http://www.emastercam.com/board/index.php?showtopic=65470

Murlin send it over and I can try with NX as well.

I have not watch the entire video but it looks great! Are they still using the Siemens solid kernel?

Carmen, Do you work in Georgetown? I live in Milton.

It has the 810 control.

Has anybody ever used these Nine9 cutting tools? http://everede.net/nine9_2012_pageflip_catalog.html I was looking at the index able engraving tool.

You can put me on that list as well! I would take a HASS anyday ove this crap.

No it is like it is dwelling or over traveling in the X direction. Sure a witness mark would be fine but not something you can not file out. Shop Turn is great and pretty easy to use. I wish Mastercam would take a few ques from it. You can program 90% of your parts on the machine. The only thing I would say against the control is since it is pc based it seems like there are "bugs", more on that later. The quality of the machine is $hit, they have been into our shop 4 times to realign the turret. So upon delivery the live tooling would not engage, turns out the shims were not ground corectly and the spline rotation was off. So after a couple of months DMG agrees to send a factory service guy from China to re-align the turret. Well the local guy did not let the "factory" guy do much. Heck they did not even lift the entire turret off even though the shims were covered in thick crap (should have seen the burrs on the shims). The pryed the turret up one side at a time with screw drivers and pry bars. After they had the shims ground they tried to align the turret with there VDI-30 Test mandrel. Well it turns out the mandrel was bent, so all the machines that they had repaired or aligned were off. The put another mandrel in and told me it was within 10 microns. They had a local guy come in and laser the x and z travels for repeatability. So when the local DMG service engineer leaves he says the next time I see you will be when you crash the machine. At this point we were 9 months since delivery and we still had not produced any parts. I start going through making some simple programs going over my notes etc, they send the applications engineer back in for a day of refresher given the lag since the original training in June. I was getting these lines that we are talking about but he had no answers, but I was also getting some diameter differences. I order my own VDI-30 test mandrel and .00005" indicator and do some checking. The turret was out more then 0.01" (ten thousand), so I call them back up. I had to tell them the the second coolant hose had rotted through again as well tell them the turret was not correct. The service manager said it couldn't be. They send out a different local DMG service egineer. He puts in his test mandrel and says it is out a lot, he then says the bolts that fasten the revolving disc of the turret to the turret are all loose. He then asks me if I loosened them? I am already pi$$ed off so I let into the guy. He re-aligns the turret with his mandrel and leaves without calibrating the tool probe. On his service report he puts the aligment is within 0.01mm (10 microns). The next day I put my mandrel up on the surface plate and indicate it and it is within 4 microns, I then put it back into the machine and check the alignment. It is out 0.0015". I then call the service manager he tells me that their mandrel is "new" and calibrated from Germany, I phyiscally held their mandrel and it was far from new! So they send the service engineer back the next week. He uses my mandrel as he says his is not new and it is indeed out. He aligns it in one pocket then I make him put it into another pocket 180 degrees and it is out 30microns in the X axis. He then goes back and spilts the difference. He still does not calibrate my tool probe. He takes the coolant hose with him and they agree to get a decent hose made. I showed the service engineer some intermitant keyboard/ control problems that the applications guy wittnessed as well but neither had answers. He leaves and I calibrate the tool probe with the supplied calibration tool, I then run the above part again and the diameters are still off about 0.004". When I am measuring the tools after calibrating the probe I hit the open door button and the entire control shuts off as if I had hit the estop. I re-start the machine and then get an main contactor fault message. I call the applications guy and he has no idea other then hit reset to clear the error. As of today we are 10 months after delivery and the machine is still in no condition to produce accurate parts IMHO. There is more but this is a coles notes version. Sorry for any typos!

It was doing it the last time the DMG applications guy was here and he had no clue. He thought programing it in Mastercam might help!

All sides.

Here is a photo of the problem area.

They did a laser test for repeatability and the guy said it was within microns.

Yes it is. Can this be fixed? Machine only has about 10 hours on it.
