  1. MayDay - Nice Post - did your "Dealer" help you with that??
  2. 3 days old and on the ball field... I bet that the little one made better calls than the officials...

    In a related note - I just had a call from Memmex (the link above) speaking to this topic. From the conversation - and a nominal cost - it looks like they can provide an accellerator board for the machine as you are asking. Give them a call - I'm sure it would be worth that at a minimum.
  4. 2. There is no kidney theft ring in New Orleans. No one is waking up in a bathtub full of ice, even if a friend of a friend swears it happened to their cousin. If you are hell-bent on believing the kidney-theft ring stories, see http://urbanlegends.tqn.com /library/weekly/aa062997.htm. And I quote "The National Kidney Foundation has repeatedly issued requests for actual victims of organ thieves to come forward and tell their stories. None have." That's "none" as in "zero". Not even your friend's cousin. Rek'd, This is the only one that I would like to refute - the reason no one has come forward is because they are dead - once you harvest an organ, the host tends to die, thereby precluding anyone from actually coming forward. Now I can actually say that they are harvesting stem cells from heathy living adults - I have been to a shop full of these "Donors" and can attest that most of them are braindead and still alive (though most higher thought functions have been eliminated in the interest of production). The reason that you don't hear about this one is that the "Donors" don't actually realize that they have reduced capability (didn't you see Hannibal??)
  5. it is summer in the dominican right now isnt it It's always summer in the DR
  6. Clean the Windows man - I can hardly see the snow!
  7. You've raised a good question, and it's my opinion that which package would be the "best" depends on what your son plans on doing after graduation. In addition to this, it will take the prospective employer 6 months to a year to actually train the employee in how to do their job. The software that you learn is not as important as the methodology of how to do things, and just by participating in a class will show that the emploee is trainable. The employer will - if they are smart - send the employee for professional training, regardless of what they have previously "Learned". Council you son more in the finer points of having a Job - Show up everyday, ontime, ready to work, sober, fully rested (so he doesn't get caught sleeping...) and don't be afraid to ask questions - there is nothing I find more frustrating then someone who says they can do something only to find out hours later that they are spinning their wheels... A promise is a promise and if you are not going to do it, don't say that you will.
  8. Publish your real name and all will be forgiven...
  9. Glenn, I am not able to duplicate this either, I did notice this at first with a fresh install of SP2, I have since done some configuration and now the problem is not apparent to me. The problem may have been related directly to WCS and now, as is the suggestion here, we will not use a feature that we need.
  10. I have done the same - great piece of tooling here. The limit is approaching a shoulder, if you have an agressive doc (around .400 radial) the chips may pinch between the tool and the shoulder of the workpiece and thus breaking the tool. Otherwise, turn up the sfm and top out at 700 - too much more and the insert will get too hot!
  11. What Todd said... Don't try to use WCS or tool planes for turning operations in Lathe. You must move the geometry. I have a severe proble with this as well. The Integrex and the part we machine requires multiple tool planes and the post I am using is a lathe post with milling functions added. I need this function and have spent hours trying to get it right. The other little problem is between SP1 and SP2 - there is a rotational shift of 90 degrees on the tool paths and so if one programmer (SP2) is doing some festures in on a legacy SP1 file, then there is an error amount in the finla outcome. Please address this - your maintenance users are expecting it to be fixed.

  13. The high end parametric modeller and manufacturing suites that needed to run on cost prohibitive hardware platforms are now down to 3 - Pro/E, Unigraphics, and Catia. With the advances in computers, they have now become much more cost accessable to the medium sized organizations that require multiple locations and collaborations - complete with some sofisticated data management capabilities. The other packages are PC versions of the above. SolidWorks was concieved by a group of disgruntled PTC employees and SolidEdge is a derivitive of UG. Inventor is a mechanical attempt at applying archetechural software to 3D and there are other stragglers in the marketplace. My first experience with solid modeling and 3D was with Cadkey in the late 80's (are they still around??) Anyway - the objective is to learn all you can - the skills and methodologies are roughly translatable form one to the next.
  14. Myth "the cost of a Pro-E/NC engineer who has the machining knowledge to make it worthwhile, you could probably get 4 or 5 Mill Lvl 3 seats of Mastercam with solids and Pro-E converters and you may already have the people to run those seats in house" This is compltely false. You can buy seats of Pro/Nc and UGNX for about the same cost of Mastercam L3 and you get a parametric modeller built in. I have the P/O's to prove it.
  15. This was very informative - this section in particular. < The effect of a low proportion of thread height is to reduce the shear area of the external thread, this is illustrated in figure 1. For very low thread heights, the shear plane through the threads need not be parallel to the thread axis, this is illustrated in figure 2. Such failure modes are difficult to predict and can be easily eliminated by maintaining a reasonable percentage thread height.>> In general - 1.5 to 2 times thread engagement at 60% will be sufficient. Thread Quality and acceptance is defined by ASME and the pitch diameter is the principle concern. See Machinery's for more information.
  16. One other thing that may be influencing the thread is the tap itself. Use a spiral point tap to push the chips in a thru hole. If you are using a conventional hand tap, the chip gullets will fill up with swarf and you will overtorque because of this. Also use plenty of thick threading paste applied to the hole - not the tap. My favorite tap is an emuge and this will work very well for you.
  17. Chris, Used conventional Turning tools and created some deep screw profiles using a side and face tool. We also ground some bearing fits. Sales promised a delivery based on carbon steel and I am the villian because this thing has a compairitive machinability coefficient of .2 - so after 4 weeks, I now list to the left from the selective A$$ chewing that took place. Jacks learning curve - I'm there man... Tim - Thanks for the information. My set MDHB is pretty much to keep dust off of the book shelf for the same reasons you indicated.
  18. The difference is the clearance angle behind the insert. The DNMG is 90 degree shoulder behind the cutting edge and the DCMT gives a 7 degree clearance behind the cutting edge. Sure the DNMG is tipped in the holder to give net clearance but the DCMT will give much lighter cutting pressure. Size and clamping are the other advantages over the other - the "C" will allow use in smaller tools and the "N" is for use on the large ones.
  19. Tim Johnson 2002 - Please indicate the source of the information that you have presented. I am looking for similar data sheets for other material groups and that looks quite comprehensive. Thanks
  20. I just finished a Nitronic 50 Job. SFM for turning was in the order of 300sfm and feed was normal per the chip breaker of the insert. Material work hardens so keep this in mind. Surface Finish comes up Beautiful and the approximate run time differential was 4 times that of carbon steel (keep an eye on your schedule and don't lie to your customer by underestimating the time to finish the job) Milling, drilling and tapping - think Hastelloy C or equiv for cutting characteristics. Metalurigically this is more like a modified 309L stainless and if you are going to weld this stuff, there are galvanic corrosion possibilities so just be careful and do your homework.
  21. www.cncci.com - navigate to the online store. Parametric Programming For CNC Machine Tools And Touch Probes by Mike Lynch 433 pages - 150 illustrations Published by The Society of Manufacturing Engineers $95.00 I have this reference and it is fantastic.
  22. He didn't tip the insert...
  23. Cost suggestion - as indicated earlier, the customization post part is chargable and by the same token, this customization will be user preference/Machine dependant so what I would suggest is to up the cost of Post Mods slightly and include this as extra value in that process. Differentiates you from the competition and adds sales like justification to the high priced help. My suggestion...
  24. That is pretty cool, but you should check this out too.. Rek'd with the time differential in the initial postings, The name should be - Duplicate Post Initiation Box...
