We had a great time last week at the old Kellogg House at Cal Poly. Here are a few pictures that Karen Rockwood took. If anyone else has some, let me know. Thanks Karen!

Komo Router problem
A few months ago, Greg Rockwood and I traveled to Salt Lake City to ITT's composite facility (formerly EDO) to investigate problems with a 5 Axis Komo Router. Since it was new, the machine had centerline problems with the A axis. We were even asked to quote a retrofit for the Fanuc 150 control so the Siemens Traori pivot point compensation could be added. I discouraged that and Greg and I verified that there was a real mechanical problem. Here is a video showing what the guys at Studwell found after shipping the whole Z, A, and C assembly back here. Only one half of the head has a problem.

The end of GEFanuc
Well, its official: The end of GEFanuc. As of last Friday, GEFanuc no longer exists. Karl and Stan both work for Fanuc America now. We don't think this will have a very large impact on us, although parts were cheaper through GEFanuc. Apparently, the Express ordering system will stay in place for retrofitters. We've not heard if they are going to change our multiplier yet. We'll see.

Verizon problems
Bill tells me that he's experienced several instances of delayed texts and voice mails recently. Has anyone else been having problems?

Dprnt Project at Circle Machine
Gilbert just finished an interesting project at Circle Machine. As some of you know, they've had SMW rotary tables and controllers on two of their Hardinge VMC's for quite awhile. In addition to these, they had custom tilting mechanisms too.
Recently, they got a trunion/rotary table from another Kennemetal division and bought a two axis controller for it from Haas. The new Haas servo controller accepts Fanuc Macro B Dprnt statements (loaded via a second RS-232 port) so we decided to try to use those instead of the old stored program M-Code/Fin system they used before. The main advantage is that they just program the A and B axis in the part program now. A singe M-code/Fin combination still executes the motion and holds the machine until it is complete, but they no longer need to pre-store the A and B values in the Haas memory.
If anyone knows of a customer who may be considering an add on rotary, we are well versed on how to help integrate Dprnt into both the machine and the programming department.

Health Net Cards
OK - They're here!
The Health Net cards are finally here. Sharon has them. If you need it before you can get to the office, she or I will be glad to read you the pertinent information and/or fax it somewhere.
As I mentioned, this should be a pretty easy transition. The HSA stays the same. Health Net has agreed to accept our previously paid 2009 deductibles and each of us who has had medical expenses this year will need to get statements from Blue Shield to verify the amount. (More about that later).
I suggest you take a few minutes to log into the Health Net website and register. I've found that having the online Blue Shield documents has been a big help.
Even though the cards were issued a couple of days ago, coverage began November 1.
Call or write me with any questions. Let me know how you like working with these guys.
Through the magic of Tamiflu and azithromycin, I'm feeling human again. Neither of my two recent doctors seemed to care what I just had, and I was not tested for H1N1. Whatever it was, it was BAD. The fact that I had a regular flu shot leads me to the H1N1 conclusion, but I guess I'll never know.

Fanuc Servo Tuning, H1N1 Flu
When one has the flu, whether it is seasonal flu 2009 or H1N1 (I went home Thursday with one of these) one has time to catch up on all kinds of reading. If you glance at the document below, you will probably begin to see how much Fanuc has advanced the state of servo performance from the Fanuc 5/6/11 vintage drives we've become accustomed to.
Have you ever been asked to adjust backlash acceleration? Have you ever considered whether a machine has HRV1, 2 or 3 type servos?
Some of you have been discussing Ball Bar testing with me recently, and this book addresses some of the things that get checked with a Ball Bar test, that couldn't be seen with an indicator and an experienced person.
We need to keep up, so during these slow times, take some books home.
I hope to be back soon.
