I have an idea this was not quite fair. No way the hp requirements of that
cut exceeded the hp of the machine. My 15 hp fadal could do that cut.
Proly a 5 hp machine could.
Ahm no 'spert, but vmc's have a way of detecting a crash condition, and it
looks like that's what was happening here. If he came in at, say, 60 ipm,
and then *ramped up to 120 ipm*, I'll bet good bucks that the Haas would not
have alarmed out.
If this is the case, one could arger that the Haas was a *safer* machine,
and that you just have to work around this a bit, from a production pov, but
once worked around, will still have better "crash protection".
I don't think anyone, not even Haas, would debate that the makino is a
"better" machine. It all boils down what you actually require, and
bang-fer-yer-buck.
Also, I don't think ramping up is such a bad idea, anyway, altho mebbe
unnecessary once a program has been proved out, for full production.
you need to get a torque-curve chart from the manufacturer. A machinist
should in any case. You have to know what your machine is capable of, t
o get maximum use out of it without damaging it.
e are plenty of options as to DOC, RPM, and Feed-Rate. It might not equa
l the Makino PS95 in cutting speed, but you could probably buy THREE Haas m
ills for the price of ONE PS95.
, or less productive? The answer to THAT particular question has been as
ked by shop owners for decades, and depends on the type of work a particula
r shop does.
BottleBoob,
You're trying to teach a rock to float.
Jon hasn't a clue that people need to read and understand machine
specifications before they buy and hopefully before they try to
program them.
As for the guy who made the video, I feel sorry for him for one day
(unlike a Banquer) he may come to understand his mistake.
Hey, Bob, a machine I am setting up on right now, just ran (an in the
machine) probing cycle on two critical dimensions. Reading came out
(X) 5.64034094488" & (Y) 3.64034094488" WTF? you say, 6 million pulse
per revolution encoders...........LOL.
Good to see you still breathing,
Tom

Jeesh, can't a guy get any respect around here... That's BattleBoob.

I wonder if there might be a spot across the torque/Horsepower curve wh
ere the Haas might outperform the Makino. Probably not given the 140 ft-lb
s of the Makino vs. the 90 ft-lbs of the Haas. But ya never know.
If I were head of Haas public relations I'd be having the peons working
overtime to try and find one. LOL
Now that's just goofy, that many decimal places aren't even repeata
ble if you just BREATHE on the part. :)
Thanks. Yeah, I'm still kickin'. My posting in here recently is d
efinitely an anomaly, I'll be crawling back into my reclusive Batcave in sh

rve where the Haas might outperform the Makino. Probably not given the 1
40 ft-lbs of the Makino vs. the 90 ft-lbs of the Haas. But ya never know

orking overtime to try
It just boggles the mind that a person would buy a Haas and then
complain they got a Haas. WTF, if your responsible for making the
decision then who's at fault, its called due diligence for a reason.
As for Jon thinking the video validates his previous clueless rants on
Haas and their HP ratings. Two machines shown in the video are from
two completely different classes the video demonstrates the
performance is not equal, WTF, what would any sane, knowledgeable
person expect, they ARE NOT EQUAL, all you need do is read the
manufacturers specs.
Dear Jon, Dear Dear Jon, Poor Poor Jon, Bob pointed you to the
manufacturers HP-Torque Chart, gave you the formula for calculating
material removal rate and converting material removal rate to
horsepower (required) and STILL you haven't a clue. It's true, you
must be twins cause no one person can be this stupid. Clue, Spindle
Motor HP rating is NOT the only variable (dumb ass).
en repeatable if you just BREATHE on the part. :)
Yes a bit goofy. In this example it was the first part and I hadn't
refined the macro yet so I looked up the actual reading in one
parameter and the variation from mean in another for each dimension
checked. Not normal for anyone to read them. For production I will set
the dim. mean, give it a tolerance, depending upon the reading it will
make an automatic offset to tool or change to another tool or stop the
process altogether and notify the operator (alarm message). I just
found the raw readings humorous when reading this thread.
The machine is guaranteed .00002" repeatability and the probe is the
same. Machine is very rigid and thermally stable so we bought a gauge
standard (linear and radial surfaces) to guarantee exactly what we are
getting for in process inspection. Helps to place the next jobs
material in the shop next to the machine for a day or two so it
normalizes.
Here's a kicker for you, it's a 5 axis VMC trunnion with a lathe
function. Turning tools load into the spindle, C Axis is the lathe
spindle and the Rotary (A) Axis doesn't have to be vertical or
horizontal it can be either/or/and. I've run it both Horizontal and
Vertical but haven't tried any angles in between.
recently is definitely an anomaly, I'll be crawling back into my reclusive
Batcave in short order.
Nice snip Jon, you managed to change the context,

What I forgot to mention in my last post was that the shit hit the fan
when
someone showed me the invoice saying it was time to pay and asked me
for an OK,
They did not forget any items in the invoice they just didn't ship me
my
order. That is when I wrote a one page fax canceling our order and a
copy of
both pages of our purchase order. It was kind of funny that I
received a call
from my VAR before the last page was sent. How in the hell can you
bill
someone and not confirm that the shipment has been made.

Jon, I never forgot any of your postings about SDRC I made the wrong
decision
in spite of what you said. There have been a number of times that my
Wife has
told me to be careful in dealing with someone and after words says "I
told you
so". She earned the right to say it as well as you have earned the
right to
say I TOLD YOU SO. I made a decision that went against my better
judgment and
as usual it turned out poorly.
Although I wanted to be loyal to a product that had been good to me
and give
them a chance and the benefit of the doubt. In return I got royally
screwed.
Loyalty does not seem to be in the SDRC Dictionary and Customer
Service is a
four letter word.

In this case my PO had terms and conditions to protect us (the buyer).
I canceled the order, they received no money from us.
Nice try at editing my post so you could change the context, what you
forgot to leave in:

Around that time Jon (1998) I thought you actually knew something
about CAD/CAM. Like most that come into contact with you here and
elsewhere, at first we think you know something till you start talking
about the programs we know and/or use, that's when your false facade
cracks and falls away and we're just left with a clueless clown (CC/
CAD/CAM technology leaders group).
The funny thing about your statement of the time that "SDRC doesn't
know how to market to job shops" never changes and like a broken clock
which shows the correct time twice a day you were correct in this
case. But that's no why I didn't buy, that's not the only reason why I
canceled the PO, I could have forgiven all and they could have
corrected any outstanding issues with us if only the software was any
good. The SOFTWARE SUCKED JON and you totally missed that.....LOL.
They couldn't sell to small machine shops because THE SOFTWARE SUCKED.
