use it everyday, a useful tool
for doing multiple sides on parts
I use it for multiple set ups on 3 axis
machining. this way I can see the outcome of the part right in mastercam.
You could try to convert the library to
a text file, then convert the text file to a library.
nc utils > def.tools > library
right click mouse when tool library is open
select: convert library to text
then after that is done repeat, but select
create library from text.
back up old tool library first.
Try this,
if mach_ltr > four | mach_ltr < one,
[
result=mprnt[smacherror]
exit post
]
it will come up with an error, and exit post
this will result in a partial nc file.
I looked at this file, did a little work on it
and put a file called board1 in the mc9 folder on the ftp site.
take a look at it, if you are going to cut butterboard feedrates could be way higher.
the way it is now it takes about 9 hours.
If you are using ver 9.1
You could try to use the surface finish contour.
in the gap settings uncheck:
check transition motion for gouge
check retract motion for gouge
in the transition section
choose:
broken
check box on for entry/exit arc/line
This will do undercuts when set like this on multiple surfaces.
The cutter sounds good to use, they work well.
You could also try a convex radius cutter, they also work well.
Stefan,
Does it take a long time to open
the tool library just to get a tool?
If it does take awhile, try this:
convert the .tl9 file to
a text file, then converted the text file to
a .tl9 file.
Had the same problem this seemed to
fix it.
I had the same problem.
To resolve it:
make a copy of your tool library just in case.
go to main menu > ncutils >
def.tools > library
when it does come up,
right click on library, convert to text file
save it. I saved it as the same name
then convert it back to a library from the text
file. use original library name
this worked for me.
and works fine off of network also.
Scott,
I really prefer format2, although you may run into a few post issues. format2 seems to be a little easier for alot of fixture offsets.
In format2 you are allowed 48. Also, some of the
fixed cycles may be a little different.
I use this feature quite often.
The collision check is for any rapid moves cutting into part. true solid verification
only shows the finished cut, although in turbo mode you can have it stop on collisions. I prefer
to run the collision check, it seems to work very well. A collision may not show up in verification,
but only on the cut part. Due to tool flex etc...
If this is a compaq computer, a couple of suggestions would be to first,
update the bios, then use compaqs driver for
the nvidia chipset.
I found that the nvidia driver from there website
did not fix the problems.
I use a deskpro workstaton 300 from compaq.
I had a few problems with graphics, updated the bios and used compaqs driver and the problems were fixed.
If I understand what you are trying to do,
with a G99,
the post will need to output the original
clearance plane when the cycle is cancelled.
with a simple G80 the tool will stay at the
R plane.
That was exactly what I was looking for.
Now I can play around with a tapered tool for sufacing. I do not know if this will work or not.
This may be a silly question, but I know the
old metacut view program used theoretical tip diameter. Not the full radius diameter at the
tangency point.
Does anyone know what the new metacut utilities uses?
Thanks for the replies on this.
I would only need to do this on e very deep mold
with no clearance for an extended holder, that is extramely deep with a small radius in the bottom corners. like .047" radius at 3"+ deep blending up to a 3 degree wall. This is where a 2d cut would not really work, with radius' blending in on everything.
I think I will play around with this and see what can actually be done with a tapered ball end mill.
Jack,
thanks for the reply, but what I actually was looking for was where is the tool diameter calculated from. Is it the theoretical flat,
before the radius of the ball end. Or is it the tangency location of the radius.
This would make a big difference in the toolpath.
When using a tapered ball end mill on 3 axis
surfacing. Is the diameter to describe at the tangency point of the radius, or the tip diameter before the radius.
I have never had to do this before but it would be a nice thing to know if needed.
Thanks
Kevin,
I just played with the file some more.
The incremntal retract is .100 and the depth was
-.05 incremental, which adds up to .100.
(-.05 inc. + .100 retract inc.)this is causing the post to output a G99. I changed the retract to .101 incremental and it now will output a G98.
I looked at my default ops and noticed I have all my drill cycles output a .125 clearance plane.
That may be one reason I have never ran into this before.
I have never ran into this before,
but I looked at the file. The only thing I could come up with was the incremental top of stock,
had a bearing on this. When I drill holes I always leave top of stock set at absolute, since this has no bearing on the drill cycle except for the G98 G99 plane. Leaving top of stock at absolute will always give you a G98 unless retract = clearance.
I use the new wcs system all the time for top and
bottom work.
Your problem may be in the verification settings themselves. It will not work in turbo mode at all.
Then use wireframe tool.
Make sure the wcs, tplane, and gview are not at new wcs view. Also, regen the drawing before verification.
Hope this helps.
another thing to try is to post process the
program without line numbers. the date line has no line number in it. the newer fadal controls will automatically give you line numbers, so line numbers not really needed anymore.
I would probably agree with Jim on this.
Another thing I just have found out is the monitor sometimes gives you a prblem.
I had a compaq v1100 monitor and had the same problem. switched to a NEC multi sync xv17 and the problem disappeared.
