i changed a parameter and it goes the shortest rout now.

i tried forcing my C output to 1 degree indexing in the mach def but that had no effect.
It appears to me that the logic isn't built into my post. Can someone point me in the right direction what logic i have to add to the post. I probably have to add some variables then capture parameters from the machine definition but then where would i place this logic?
Or can someone post some of their logic out of their post for this?
thanks a bunch!

I've run into some weird problems with C Face contour.
I tried contouring a cirlce. Code should be simple x move in, c rotate 360 then x move out.
On this file with the circle i'm trying to contour at (center) 0,0,0 this is the code:
O00000001 G20 G52.5 T0505.00 M200 M8 G90 G0 G54 Z.155 X7.156 C0. G97 S2500 M203 Z.005 G98 G1 Z-.395 F20. X6.956 F30. C360. F494.21 C720. C1080. C1440. C1800. C2160. C2520. C2880. C3240. C3600. C3960. C4320. C4680. C5040. C5400. C5760. C6120. C6480. C6840. C7200. C7560. C7920. C8280. C8640. C9000. . ..(Code truncated for length) . C65160. C65520. C65880. C66240. C66600. C66960. X7.156 F30. G0 Z.155 M9 G28 U0. G28 W0. H0. M205 T0500 G99 M02 %
this code is obviousely not right. However if i move the center of the circle .0001 in the x direction i get code i can atleast run:

yet when i open a new file and do the same exact toolpath with the circle center @ 0,0,0 i get the code i actually want:

WTF? is this a bug or is something in my file affecting this?

figured it out. i'm an idiot.
accidently turned on dry run

so i tried some code out today. big fail(no crash of course!)
This is on a Mazak QT350M with C and live toys.
i tried a g12.1 but all i got was an illegal g code alarm. I thought i might not have that option but it lists G13.1 in the active modal commands. Do i have to have a Milling tool specified in the tool data?
Then if i MDI'd g98c180.F1000.00 the c would position to C180 quickly.
in my program however it would go MUCH slower. I looked at the F on the display and it read 10. instead of 1000. ?!?!?!
The program was ignoring/changing all my other feed rate commands too!
is there any reason why it would ignore my feedrate command? I'm ready to tear my hair out!
Could it be the way the tool is set up? I'm new to Mazaks and no one in my shop has run ISO code through the lathes, but maybe it takes the tool definitions alot more seriously in ISO mode than i thought.
the tool was defined as a drill so maybe that could be my problem? I only get limited time to play with these so i don't wanna break down our production setups.
Any help would be greatly appreciated, maybe a g12.1 milling example too

Any code examples would be exteeeeeeemly helpfull as i'm new to this machine, c-axis, and live toys. Gotta love learning through the good ole crash course!
thanks a bunch for the help, i'm gonna need it!

I'm wondering if there is any reason why always using g12.1(Polar Interpolation) for face contour operations would be a bad idea?
just a thought as i'm building my post.
opinions? comments?

found this in my post:

Sorry, not too familiar with the MT post, did you try changing things in the MD?
yes is is set to 0-359.999 in the MD. It looks to me as if this logic isn't built in already.......
-
What post are you using?
Changing these below from zero to two worked for me...
pang_output : 2 #Angle output options, primary sang_output : 2 #Angle output options, secondary #0 = Normal angle output #1 = Signed absolute output, 0 - 360 #2 = Implied shortest direction absolute output, 0 - 360I am using GENERIC FANUC 4X MT_LATHE post.
I cannot find pang_output and sang_output either
-
How do i limit my C axis output to 0-359.9999?
Is there a benefit to doing this at all? i feel it might be simpler code for c-x contour toolpaths.
-
Both are chained the same direction and are offset the same (right/left)
lol i tried again and they bost post the same direction now!
damn u mastercam, i guess a restart is needed sometimes.
-
I'm having some trouble with a Mazak lathe at work.
With the axis @ C0.0, if i MDI C10.0, then C5.0, the machine will go to C10.0 in the positive directions, then go to C5.0 but go all the way around in the positive direction instead of going in the negative direction.
Is there a parameter i can change to force the C to go to that absolute position in the shortest direction?
Also, how do you all like to program your c for c-x contour moves? This is all a learning experience so anything helps lol!
thankx!
-
I have two c face contour c axis toolpaths, both backplot in the same C directions but one posts out C+ and one posts out C-
Am i missing a setting in the toolpath somewhere?
I tried setting the rotary direction on the C axis in the machine definition but it didnt change anything?
what am i missing here? any help would be greatly appreciated! thanx!
-
figured it out.
i'm a retard!
you need to have subprograms active for canned cycles to work.
gotta love spending a few hours scouring your post only to find out it was just a checkbox lol!
-
I've gotten the Generic Fanuc 4ax lathe post to output canned cycles but for the life of me i havn't been able to figure out how to make a stock Fanuc 2ax lathe post to output Lathe canned cycles. It outputs all longhanded code. I have the canned cycles checked in the machine def and i have the longhand code option unchecked in the toolpath.
any help this is driving me CRAZY!
thanks a bunch!

Hey all,
is there a convertor to convert dimensioned solidworks files to mastercam files with MBD attached to them?
thanks!
-
how would i look for the operation type, i.e. face, rough,finish, groove.
what parameter/variable am i looking for here?
thanks a bunch!
-
still not working. would like to get this running as i have ALOT of post work to do!
any help would be greatly appreciated.
still get the same error as last time.
-
How would you post a tooltable at the end of your program right after an m30?
Tried Ptooltable at Peof but it only output the first tool????
any hints?
thanks a bunch!
-
how do you do it?
can't figure out how to creat the new geo on another level.
thanks a bunch!
Nevermind i figured it out!

-
could someone post an example of reading from a buffer file(text file) and inputting that data into the post.
thanks!

I'd suggest posting that question over in the Post Processor forum.
One of the Post experts should be able to assist.
sounds good. thanks!
Mazak 510c-II Spindle/tool problems
in Machining, Tools, Cutting & Probing
Posted
2006 Mazak 510C-II with a Matrix Controll.
Recently, while hogging with a 3" facemill @ around 900RPM, @ random points the spindle would start making a noise that seemed like a dying dog howling. The sound was definatly cyclic in nature. After stopping the machine to investigage and finding we couldn't reproduce the noise, we would start running the program again and all was fine untill the next day, when the noise came back. This is the same cutting parameters, they varied from 125 IPM @.050DOC to [email protected] DOC for that tool (in mild steel)
This started last week. We haven't run any new programs on the machine as now other things are acting up
Now when changing a tool, the drawbar will catch and engage the tool but the tool will not be fully seated into the taper. when u turn on the thru spindle coolant you can see it shooting out the gap between the taper and tool holder.
Any hints on to what our problem could be?
What could that noise have been? I feel it has something to do with some spinning mechanism in the drawbar assembly.
thanks for the help!
