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

been there, done that, got a closet full of t-shirts to prove it Ken,

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.

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 HTH Ken,

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. HTH, Ken

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. HTH, Ken

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. HTH Ken,

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 Ken

+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.
-
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. Ken
-
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. HTH Ken

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. HTH Ken,

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

My method of tool length measurement
kh012 replied to badbascom's topic in Machining, Tools, Cutting & Probing
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.

My method of tool length measurement
kh012 replied to badbascom's topic in Machining, Tools, Cutting & Probing
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. Ken,
-
^^^+1 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. Ken,

hit the key twice sorry
-
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 Ken,

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. Ken,

^^1 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. Ken,
