Point taken. I've found great help in the person of Mr Chris Rogers,who
shares your view, and we'll try to get a general discussion forum going
that allows cross-discussion of several commercial codes, general
theoretical discussion and also comparison with other techniques, such as
hand methods and finite differences to be discussed along with FEA. I
think this would allow it to be placed, as you suggest, in the sci.engr
hierarchy where it logically belongs; also, being more general, it stands
a better chance in a vote.
I apologize for appearing to ignore your advice, but I'm not familiar with
this system and failed to get your point on your first post.

I hate to rain on your parade, but if your objective is to have a lathe
to do jewelry work, as opposed to designing and building a lathe, or
developing a new lathe specifically for jewelry work, that you then
intend to manufacture/market/sell; then I would strongly suggest buying
either a new or used lathe that most closely fits your needs. I am
certain that there are small lathes available for this type of work.
Invest your research into talking to jewelers (that do custom work),
model makers etc. finding out what is on the market, then try and find
one new or used. This is the fastest and cheapest method. If the
thought of spending $1000 to $5000 on a lathe and tooling scares you
and you think you can build something cheaper, banish that thought now.
Designing and building a lathe is a substantial effort. Anything that
you plan to build that would have good accuracy and rigidity and be
usable requires extensive knowlege of machine design, bearing fits,
precision alignment of components............ After all that, then you
have to detail the parts (make drawings) so that someone can make them
(unless you make the parts yourself). Raw materials and components
(gears, motors, couplings, shafting....) will end up costing far more
than you expect, but by far, machining the parts will end up costing
more than a whole new machine. I own an engineering design firm that
has its own prototype machine shop, I have the tools to do such a job,
and it would be worth the effort.
I frequently see posts from people that think they can make something
cheaper than they can purchase it. This is rarely, if ever the case.
The only people that can turn old transistor radios, scrap metal,baling
wire, odds and ends and coconuts into some useful functioning device
are the Professor (of Gilligans island), Spock and maybe Scotty (Star
Trek) and McGiver, and we all know they're make-believe.
Subject: Opinions on CNC VMC's (vertical macining centers)
From: jbower@ix.netcom.com(John Bower)
Date: 3 Jan 1997 08:56:03 GMT
My company provides rapid product development and engineering services
for clients in a wide variety of fields. In addition to engineering
analysis and design, we also have a well equipped prototype machine
shop. Presently our machines are all manual, and we are looking into
the purchase of a CNC vertical milling machine. I am trying to get
input from people with first hand experience with VMC's as a part of
our research. Hard facts as well as personal preferences are
appreciated. Our preliminary requirements are:
Can machine plastics, aluminum, steel and stainless steel
Capable of 3D contouring
Tool changer (probably, what are the pros/cons?)
5-30 HP head
NEW or USED Ok
Ability to run from downloaded files from PC CAM programs like
MasterCam, SurfCam, etc.
3 phase power 220 V preferred (not 440)
Min 18"x18"x12" work volume
$15k to $80k price range
I've been to several machine tool shows, familiar with several brands,
somewhat considering Haas, Fadal, Kitamura, Matsura (expensive but
good), though this is based on a very small amount of input.
Would like to hear opinions on:
Brand names and reliability
Cost of upkeep, frequency of repair
"Must have" features
Things to avoid
Tradeoffs between newer versus older technology
New machines vs. used machines
Things to look out for
Thanks in advance.

At the risk of repeating much of what has already been said by many of
the poster to M.I.Q. I feel the need to point out the following.
ISO 900x has nothing to do with product quality. What a documented
system based on the model contianed in the standards does is ensure that
the product produced by the company running the system under conforms to
a written specification. i.e. if the specification calls for crap, the
system will deliver crap.
ISO 900x has nothing to do with business excellence, as system can be
inefficient and in effective interms of business performance and still
be registered by a third party as being ISO900x compliant.
ISO 900x registration, as opposed the standards, does add $5 to $5000 to
each unit, but not in terms of quality, in terms of actual cost
resulting from the overheads incurred from registration.

Urrrrrr ya got me. :-)
But even though the FAQs get some use, I don't spend 700 hours
a year maintaining them -- and that's my estimate of the minimum
engineering time required for these guys to get what they want.
(Nor is my time on the FAQs primarily "engineering hours" -- it's
more cutting and pasting what somebody wrote in another thread.
I often save threads for my own purposes, because they help me
out at work, then when they reach critical mass I organize them
for others to read. It's not as taxing a "hobby," believe me.)
>It looks like an interesting way to pass the time ( for someone with the
>time! ).
And that's one of the things that bugs me. Those who have the
time, will they have the skills and chutzpah as well? In my last
job, this is the kind of thing I was doing. And one of the things
we found was that time and time again, customers would want
the most experienced engineer to do the job, instead of the one
that was the most available. Of course, that borders on an
ethics problem. ;-)
It would be interesting to learn if sci.space.misc readers responded
to this.

Unless they are talking about the body only (i.e. sheet metal only -
*not* the frame, engine, seats, transmission, etc). Then the "body"
could be 40% lighter, yet the overall weight reduction of the vehicle
would be less than 40%.

Before you make such a statement take the trouble to learn and
understand how the ISO system works for limits and fits.

In our drawing office it is normal practice to provide the actual
range of sizes near the title block so that the machinist does not
have to refer to the standard charts.
We have found that when using the ISO system with subcontractors we
have less parts rejected. In South Africa any artisan or engineer
knows that for example a H7 / s6 combination results in a moderate
interferance fit.

Getting technical, engineering and programming work.
There are about 1500 large and very active engineering temp

Tech, and others employ thousands of engineers on a project
basis. The only central data base the majority of these
jobs is maintained on is by a company in Kirkland
Washington, run by a super nice guy named Jerry. He
publishes a print magazine that goes out weekly. You can
get 15 issue trial for under $20 I believe. He will also
mail your resume to all of these shops, hard copy, typeset,
for a few cents a copy in his weekly bulk resume mailing.
There is also the web zine. Http://www.ceweekly.com that

contract employment business and how to get yourself known,
and also a subscription electronic search and resume posting

Yeah, the sophomore year can suck pretty hard (That was the year I spent the
least time doing work, and came close to losing my scholarship money because of
it) Rest assured, though, that once you get through it, the junior year is
generally the hardest. Not that you need to learn a great deal of really
difficult theory, you'll just spent all the time you've got learning the
applications. Some of it will be interesting and you'll enjoy some work,
but(at least at Virginia Tech) the work just keeps coming at you.
I'm convinced that they structure the classes to teach you the art of resource
management, to learn which assignments need to be completed on time and which
don't. I learned to anticipate when certain homework assignments would be
collected, and my friends and I became very proficient at studying together.
Before long we had learned very well to specialize our attention in class, then
use our time out of class to bring one another up to speed. It worked well.
In summary, hang in there. Get a dedicated study group together and keep at
it. Once you're through the sophomore learn-fest and the junior do-fest, the
senior year usually relies on design and applications stuff and is generally
more relaxed. Later,
