Never enough warning,of course, needed it yesterday.
been there, done that, got a closet full of t-shirts to prove it

for custom rad's we use A-B tools. (abtoolsinc.com) they are really good and reasonable in price , quick turn around ect.
you can tell them the mat'l and they do a grind for that.
HTH Ken.

I feel like an idiot asking this ... but its a $200K piece of titanium and I DO NOT want to screw it up
1.5-12 UNJF ID thread .....
I can use a 12UN insert to thread it .... right ...
the root radius callout only applies to OD threads ... right ????
you are correct the only diff. on a unj id thread is the minor dia. is bigger to
fit the root on the od thread. if you are using a full profile id insert you
will have to bore the id to the correct dia.
there is no diff. on the id thrd gages other then the lable that says un or unj

we have 4 hardinges, they all use old posts.
I just hard coded the M98 P1 into the ltlchg$ section and the M98 P2 into the pl_retract section.
with newer posts you could get pretty creative on how to input them.

are the tool paths that you have in your mc file the regular roughing or the canned roughing.
if its the regular one the post will not convert it no matter how the switches are, you need to use the canned paths.
just a thought.

we do the same thing with alot of our prg's. all my posts are old just updated to new versions so i don't know if the newer posts
have that ability. what i ended up up doing was creating two different posts one that does the sub prg's and one that does the main prg.
i do the tool paths with the sub machine def. post it under a dummy file. then copy the tool paths into the main machine def.
post that out, then merge the dummy file into it in the editor. im going to take a hard look to see if i can do this another way.

don't know if it still will do it but with control comp it used to ignor the look ahead on some tool paths and try
and fit a larger tool into ares that it wouldn't fit. like tying roll a 1/2 em into a 3/8 wide slot.
with wear comp. you don't have that problem. its been awhile since using contol so im not sure if the newer mc's
still do this

+1^ on the polar cord. (G112). it looks like you might be driving on a slpine and not lines/arcs.
with our hardinge msy i prg. to the edge of the tool with a long lead in line. set my feed rate for the chip load i want
then the machine figures out the "C" axis feed rates to keep the chip load i want.

Ken,
What would you consider hi pressure? 200, 300 or like 1000psi?
it all depends on the size of the nozzel, really small and 200/300 might be ok, but not much beats 1000 psi.
we use cooljet pumps that put out around a 1000 psi thru a 3/16 dia. "QPM" is a company that has a wide
selection of coolant lines, nozzels etc.

we use high pressure coolant thru the tool when possible. for insrts we try and use ones with a high posi rake, this will help pull the chips
out of the bore. if the pressure is good it tends to break up the chips.

on our mori's it's a "M" code to open and close the jaws.
M11 opens the jaw, M10 closes the jaw. spindle must be stopped.
there maybe a parameter that needs to be changed to allow movment with the jaw open.
not sure what # it was.
you will also need dwells after the "M" codes to make sure the jaws are fully open or
closed before cutting.
our hardinge's with hydro bar feeds need the spindle turning to help feed the bar.

^^^+1 on the AB tools. we use alot of their tools , good stuff

Welcome
i have been using mc for around 12 years just started reading the forums about a year ago.
these guys realy know the ins and outs of mc. i have found a bunch of easy fixes for things
that i just worked around or delt with. use the search feature for any questions.
Best of luck Ken,

we use tool lenght setters or shims/gage blocks which ever is conveniant. if you use the utility cycle you tell it the hieght of
your block/shim. you can also add in the differance to Z0. the cycle will do all the calculations to set the tool length. if you
are running 21 tools on 20 fixture locations and you need to change a tool then you only have to retouch off on the first fixture.
all your -Z- fixture offsets remain unchanged. also helps if your holder/tool length changes.
HTH Ken,

on our fadals we use the utility cycle or the SL, command to touch off the tools on -Z- to wherever -Z0- is in the program.
this puts the tool length into the geomety page not the fixture offset.
our fixture -Z- values are only to set the differance in hieght between the first fixture and the second fixture etc. we also use this value to do a globle adjustment
of all the tools that run on that fixture.

For roughing i use the stepover. For finishing i use the scallop to control the max. cusp size on the surface. the smaller cusp means less manual finishing of the surface.

try plunging the slot with a 3/8 em. rough the outside leaving about .05 per side if possible.
the use the 1/4 em to step down, chaining the slot and outside as one chain if possible.
this will leave the thicker section below the cut for support.
i've done this on thin walled parts before to get rid of chatter and tool deflection.

hit the key twice sorry

I have an Integrex with a similiar set up and yes I just use the left tool plane and leave my wcs set to top, and then just use my right upper or right lower axis combo's for toolpaths. My zero on the part in mastercam stays the same. I use macro math in the machine to move my zero between spindles. Let me know if you have more questions.
HTH
we have a hardinge 8/51sp msy, that i program the same way. i copy the m/s geo. to another level then translate it to z0 on l/h end of the part.
i use the parts transfer cycle in mc to move the part to the sub. and use l/h plane for all mill work on sub. wcs top

Try "carbideprobes.com" they have a nice selection agd. 4-48 tips for drop indicators. Ball tips , thin shanks, etc.

I had a similar problem installing X5 on an XP system. Ended up having to use "regedit" and clean up the registry. Then reinstalled with no problems.
don't know about windows 7, but that is what worked for me.

I use the drafting shortcut keys all the time.
j=opens text k=lock dim.orientation n=ajust or stretch leader s=opens parameters
just a few of the keys i found usefull.
Ken,

check out gagemaker.com. they have software to calculate thread dim's. we don't have it but another local shop does.
you just put some basic info in and it will calculate all the dim's.

Question from someone that hasn't run the dynamic mill stuff yet:
If your machine can handle heavy cuts, does it really help? Take the above cycle, 1/2" endmill .820" deep in aluminum. Dynamic mill he is going .05" stepover at 220 ipm. Couldn't you just as easily go .250" stepover at 44 ipm? Cycle time would probably be faster with fewer repositions and accel/decel being less of an issue. Additionally tool life would be better because you are going through 1/5 of the material.
So what am I missing?
this was an easy part to just get my feet wet.
but after using it i now have a whole new way of removing mat'l fast.
ken
the 220 ipm was where we were at ,but still going up from there

what about spirling in from the out side. tool wear would be on the shape not a mismatch.
just thinking?
