(in response to COE Administrator)
Hey this is great stuff. What I like best is the plethora of
responses to 7..... What manufacturing topics would you like future
webinars to explore?
Looks like Mark Chitjian and James B , are going to have fun
planning, for some time to come.
MY #1 IS UP THERE
Ability to add drive surface without removing and reselecting
existing drive surfaces..... I say with MAFC, you can drive
anything, and adding this functionality, will make life more
enjoyable, for all the CATIA NC programmers, and enjoying life is
I have to apologize to all you guys. I asked my new boss 6 months
ago, you know the really really really stupid boss, to request a
temp license for me to mess with this, and he is like “if you don’t
do it some one else will so NO”…. what a dunce. But it does show
the old school attitude many have. But you know, I see the other
PACMEN came thru where I could not, at least on this subject. I can
do a lot without permission, but this require a lic request and It
to install it…….But, I do what I can and you guys have put a lot of
great things here for our friends to work with.
SHOW ME THE TOOL PATH UP TO THE POINT IT FAILS
A late idea from me, is … I would like to see on MAFC, the tool
path up to an error. The way it works now, you hit compute, and sit
and wait……. 59 seconds to go, 13 seconds to go, then it fails. An
nice message box pops up with all sorts of useful information ,
but…… I would like to see the tool path display on the part it did
calculate. If it fails on drive surface 5, let me see the motion on
drive surfaces one thru 4. Because, it may not be on the correct
side ( left / right) that I am trying to do. Any visual hints like
I am describing will help.
PLEASE EXPLAIN THE REFERENCE POINT, AND ADD FUNCTIONALITY TO
Many times, it is the darn reference point being in the wrong spot,
by I got to tell you, I have never really got a good handle that
little green point dude . I would like some rules. With NCL, you
positioned with a goto ( or from but I NEVER used from), So here’s
the deal, there were rules.
1. Always be closer to the drive surface then the check surface
2. The indirection vector pointed to the check surface.
It always worked.
Looked something like this
GOTO/ (PT/IO, (LN/PA,LN1,XL,HDIA+.1), (LN/PA,STK2,YL,HDIA+.1))
GODLTA/ (PL/PA,ZPL3,ZL,FLR+.1), ZF
THICK / FLR, WAL, WAL+.5
GO/ LN1, ZPL3, LN2, RAMPFD
MAFC DETAILING CORNERS INTERMITTENTLY FAILS, UNTIL YOU GET THE
LITTLE GREEN MAN IN THE RIGHT SPOT
I have a 5 axis part
Lots of corners to pick out.
I get a corner just right with the macros, step down, blab la
So I copy and past that MAFC cornering MO a bunch of times. It work
great on corners, but on 5 of them, I an trying reference points
all over the place. I wish I knew what to do to know were to pick.
I try here NO, and there, NO and this corner of the fixture NO, and
that railtop edge. How about this tool tab, No how about that
railtop, bzzzzzzzzzzz computed . Yayyyyyyyyyy.
WHAT IF AN ADDITIONAL POINT METHOD WAS ADDED
I always put a point, ahem , build some geometry, a center point in
The center point was useful for macro to nibble out corners
A point in the center of the pocket is always on the correct side
of wall, when picking out corners
So I could say
GOTO / CENTPT(3)
IP / (PT/IO, DS1,DS2) (indirection vector created from point
THICK / .25, .5, .2
GO/ DS1,PARTSF, DS2
RAPID, GODLTA/ CLPL
RP, GOTO/ TEMPPT
I was thinking that if we put center points in pockets, and DS
added intuitive code, that this kind of point is on the correct
side of the intersection of drive surface one and drive surface
USE THE SIDE OF THE SURFACE THE MOUSE PICKED
I will throw another one at you, though I talked about this
Use the side of the surface the mouse picked
This is the way it works now :You pick a drive surface and the
orange arrow pops up, and you can select the arrow and it will go
to the near side of the surface or the far side.
This is easy, use the side of the surface the mouse picked. If that
is attainable, then all this reference point, and orange arrow
selection would be …. Automatic
TLAXIS FANNING TO A KNOWN ANGLE
I would like the tool to fan to a given max angle while driving a
surface. For example if the surface is at 23° angle and have a
machine limitation of 20°. I would still like the tool to be able
to fan at my max given angle of 20° irrespective of what the actual
surface is. “
For Who ever said this, I discussed this with Patrick in depth, at
COE 2008 Orlando. Dassault understands the requirement, and I know
nothing of progress but we can hope. I brought a process with a 150
f22 cosmic part that looks like a ….. titanium pool slide with
pockets and ribs on the convex side. On the concave side the
swarfing M/L at one end was 18 deg and 32 deg at the other. To do
this with the CATIA I had in 2008, I created a spline thru points,
and I moved the points around and did analysis, to have the points
lie where the normal’s were 25 degrees.
The motion was like this,
TLAXIS / ATANGL, .25, PS, CLDIST, .01
TLON, GF/ DRIVCV, ON, 25STOPCV ( the stop curve )
TLAXIS / SAME
GF/ DRIVCV, PAST, RGTEOP
What I am thinking now that I am messing with machine builder…….
CATIA knows the kinematics. This is critical. We can not say Tlaxis
/ normal, ps, until B25, unless you have a machine builder license
and tell CATIA if the A is carrying the B or if the B is carrying
OK it’s almost 11pm, and that Ice cream Klondike bar rush is
wearing off, and I need my beauty rest. Actually the rush came from
reading the survey Mark, I love the way you posted the survey
before the webinar. That leaves us time to kick the tires, and more
time at the webinar.
Best Regards to all and to all a good night
