Machinist Training

Cliff,

Troll, you insult me but you can't even post simple 2 lines of simple
2 axis code without multiple mistakes and you are representing yourself
as an expert?

Eggspurt is more like it, two lines of simple code you posted earlier
in another thread and you made 2 beginners mistakes. You posted two
lines of code to prove your method of "Center-Line Programming" was
superior on a vintage Mori-Seiki SL-1 with Yasnac control. Your example
was contrary to how most people setup and program a two axis lathe. Of
the two lines of code you posted you made two mistakes, an average of
one mistake per line of code, quite an average. Wonder how many
mistakes you can make with 5 axis's?

Those who can do, those who can't Troll newsgroups, cyber-stalk JB, act
as gadfly to serious posters & cross post to every kook political group
in cyberspace.

Tom

You stated that you have been programming machines since before CNC.
The Original Poster of that Thread was asking about his SL-1, you
posted two lines of code for him and you made two mistakes. Now your
saying you don't need to produce good G Code for the original poster's
SL-1?

And how is this supposed to give us confidence you can program, setup
and operate a modern 5 axis machine let alone give informed advice on
one?

You posted two lines of G code to prove your method of Centerline
Programming was easier and more accurate on a vintage SL-1 machine than
my method and you made two mistakes proving my point for me.

All assumptions you have made and on all counts you are wrong. You
can't prove your point so you again as usual degrade yourself and your
argument by issuing insults and false accusations.

Tom

 

And was given what I considered not-the-best of sound or sage advice

Nope. I posted them is response to others, not the OP, as simple
examples.
Some were very clearly confused.

Not if I'm not programming it. And lacking any info/manuals on it .... but
my points were solid indeed.

Wrong again.
Except for certain very simple parts your method would not make good
parts. Or, if you could make added adjustments, you would be right back
at doing centerline programming with he added step of calculating added
offsets for many/most blocks of code.
AND have feedrates wrong.

Then you don't understand what it's about.
You in management?

Your lack of comprehension seems to be at issue. Do you even know
what it is about?

(He asked for the bait real nice <G>).

HTH

 

Yes you are.

 

I'm not the one that thought it was about WSP .... <G>.

 

A little more confused after you posted a total of two lines of your
sample G Code and made two mistakes. Confused as to how someone who
represents himself as an expert could be be so ignorant as to post his
two lines of code with two mistakes. Confused as to why someone would
make those mistakes and not just admit to it and move on, instead you
continue to wiggle, squirm and dance around it.

The OP and the thread were clearly about the OP's SL-1, you were the
one that kept trying to steer the topic away after you made repeated
errors in fact and also by example. You continually tried to steer the
topic away while I and others kept reminding you the topic was the OP's
SL-1 lathe.

You decided what was best for Keith without asking him about his shop,
product, machinery or his future. You knew what was best for him
without having any background information. Keith gave me his input and
I made recommendations on from what he told me about himself, his
products, machinery and future plans.

You didn't need any info/manuals to say my posted step by step
instructions for Keith to calculate his G50 settings for his SL-1 was
wrong. If you can say someone is wrong then you are representing
yourself as knowing what you were talking about. If you needed
info/manuals you should have stated so.

Your points were solid indeed, the are solidly wrong for Keith and his
SL-1. You kept assuming Keith's machine has functions it does not have.
When I pointed this out to you you kept trying to move away from
Keith's machine and talk in generalities where I kept reminding you we
were asked and made recommendations for Keith and HIS machine and HIS
type of work. All of which you never asked him about, you decided you
know what is best for EVERYONE and you are unwavering in your personal
beliefs.

Your process was adding unnecessary steps and calculations at the
machine at setup. I pointed out that the added steps are more
opportunities for mistakes to be made when Keith's control can not
utilize it because he does not have the options you were assuming he
had. Still you would not waiver, what is good for one is good for all
in your not so humble opinion.

I have programmed, setup and operated from 2 axis to 8 axis lathes (11
axis if you want to include robot loading/unloading) and from 3 to 5
axis mills.

Again accusations you have made numerous times but have not been able
to post an example profile to prove your point. Let me state here again
for you, there is no profile your method can make that mine cannot.
After numerous requests for you to post this mythical profile you still
have not. The parameters for this mythical profile being the OP,
Keith's SL-1 Lathe.

A standard cliffism, if someone disagrees with you they just don't
understand. I understand your points I just disagree with your
conclusions.

Another cliffism insult coming from you who posted this in another
thread.

Cliff wrote,

Unlike you I don't see setting up or operating a machine as being

Which are explained by some reading comreheinsion errors and
a seeming lack of grasp ....

I now doubt you know what centerline programming is by the sound
of it.

Perhaps you need pictures.

It would not matter if it was an eggbeater. Bad advice is bad advice.
It's not like simple geometry was invented yesterday.

You both seem very confused then. I'm not responsable for your
private Emails either <G>.
And none of that needs to be known to know wrong when it's that

You don't need them to spot the problem(s). They were that simple.

Nope. But Dan M did IIRC.
And that you should make such a claim (still) clearly shows that you
grasped little of this and are still missing it.

It's very basic. And simple.

I only commented on your statements.
Had you done a good job ....

I had no need to ask him about simple stuff.

Not much to speak of compared to all the later fudges YOU would
need to almost every line of code (in the general case).

There you go again. You really don't understand this, do you?

Wrong usually remains wrong.

Probably loudly indeed. 12 *simultaneous* MINUS the robots (they don't
count) is more interesting ... and even 2 axes seems to confuse you.

Are you of the Zen school of programming?

Nope. You don't begin to grasp it.

Quite correct. I HATE loud noises. And flying bits of expensive stuff ...
nor do I (or anyone else AFAIK) duck all that fast ... and repair bills
can be steep ...

That's a bit like Mot?

 

Cliff,

More Cliffisms, generalities and insults, more dancing, ducking, diving
and diverting attention away from the core issue.

You can only talk theory and generalities because that means you don't
have to prove your point you can always dance, duck, dive and divert
and your not tied down by an example that people in the group can
review. What a cowardly troll you are that you can't stand pier review.

You have been asked repeatedly by me and others to post your mythical
profile that can be turned correctly with your method and cannot be by
the method I posted.

Back in May of this year Bottlebob asked you a direct question. "When
was the last time you programmed a lathe?" Than after with multiple
posts in the same thread without an answer from you he posted "Have you
ever programmed a lathe?" Did you ever answer him? If so what was the
answer?

Actually yes, you cross-posted from comp.cad.solidworks to
alt.machines.cnc. some of JB's observations and criticism of
SolidWorks.

I can tell you from experience some of JB's observations are right on
but since all you seem to do is Troll newsgroups and cyberstalk JB you
wouldn't know.

I am currently working on a project using SolidWorks 2006, the project
I am working on is over 875 parts right now and will be over 900 parts
on completion. I can tell you JB's criticism of large assemblies is
right on.

Now having said that I want to state that I love SolidWorks 2006 and I
highly recommend it. The couple of areas where I feel improvement are
needed are far outweighed by a huge list of positive's.

The center of the TNR needs to follow a curve offset from the surface
along the surface's normal vector by the TNR.
You are offsetting in two axes by the TNR but ignoring the normal.
You can also (with a bit more complication) then offset from the
offset curve by your linear axes offsets .... and make yet more changes
to get other things to work .... but you still need that normal vector
related calculation <G>.

These things are not the same ..... LOL .... though in *simple* cases
they can look similar (with enough MDI edits & kludges).

Do you also inspect quality into the parts (sort of a
"value added" thing)?

He could not tell a constrained parametric solids modeler from
a text processing program.

You miss much of his silly idiocy then.

Perhaps if you asked nicely in comp.cad.solidworks someone
would help you with properly & effectively using your *legal* copy ....

Find any such from jb <G>.
He does not use it. Or ANY CAD or CAD/CAM or even CAM system
AFAIK.

OTOH IF he did he'd be less funny as he's have to know something
other than what others wrote that he did not grasp or what the words
in the ads were.

Don't tell jb ....

 

I haven't seen a note about the toolpath animation that some CNC
packages can do to help the programmer/cnc operator (usually one and
the same in a small shop) verify what the tool is going to do VIRTUALLY
on screen prior to sticking a tool into real metal and watching (yes
I've seen coding errors & tools snap, though a long time back).

I got out of machining with our Fadal and Gibbs software 15 years ago,
but I've seen their toolpath animation in MDDI convention
demonstrations in recent times and wondered if other code generating
CAM packages now do the same?

How did you come to this conclusion?

Where did I post that the TNR does not need to follow the offset curve?

What constitutes "simple" cases?

What type of work is Keith, the OP going to run on his vintage SL-1 2
axis lathe?

Where is your sample profile, that can be run on his machine with your
method that can't with mine?

More cliffie trollisms.

I ask you again "When was the last time you programmed a lathe? Have
you ever programmed a lathe? You have been asked numerous times and
have never answered so that in itself is an answer in the negative, you
have never programmed a cnc lathe, Cliff aka <jb>

I and others have asked you numerous times to post an example profile
that your method can produce correctly and mine can't. What is this
now, going into the mid 40th request. Again no response and no posted
example is an answer in the negative. You cannot post an example
profile that your method can properly produce and mine cannot.

I can only assume you are a desk-bound-know-it-all bookworm/computer
nerd that only knows what he has read.

Cliff,

I am unaware of what thread you are referring to but in any case he is
correct on his observation about large assemblies.

Wish I missed yours.

Didn't have to ask, only had to read comp.cad.solidworks and cherry
pick information already there.

Do you have some form of Tourette Syndrome? You just can't type a
response without adding some insult or insulting innuendo.

Comp.cad.solidworks is a good group with good people as an added pluss
you don't seem to post there much unless your cyberstalking jb.

Fairly simple geometry.

IF the offset (normal vector offset) curve's linear axes offset
is the part's surface.
IOW ..... Even a cut at an angle to an axis will be wrong ... or you have to

See prior comments in another thread.

(For those new to this old subject with Tom he's setting his tools
for 2 axes lathe work to a zero touch-off point in both axes. The
intersection point of these axes is thus out in space, away from the
actual tool nose radius {TNR} -- which cannot cut as there is no tool
there -- and then programming that point as his tool ... )

You don't check?

LOL ....

See prior posts.

Like geometry, machining, CAD/CAM, programming, best practices, fishing ....
