Thank you all for the info. I think I'll go with 2 posts/MD/WCS. You gotta love this forum. Throw out a question, roll around in the mud with all the ideas and walk away with something that works. Thank you all!!!

It's been a while, but I believe in 4 axis it makes a differance which contour is selected first.

Thanks for the replies. Guyinthedesert, The diference in center of rotation is X.014 Y.020 Z.005 so regrinding the table won't help with X & Y. DavidB, Are you using multiple posts, or machine defs? I do appreciate all the Ideas.

What machine are you running? I might be able to help if it's a Mits.

Hi all, I have two 5 axis Haas VF6TR310s. The center of rotation is slightly different for each machine, and no dynamic offsets. I would like to maintain one MCX file for each part. What is the best way to deal with the different centers of rotation? I'm currently using two manual entry toolpaths to set G54 for all 5 axis, and Ghosting one or the other depending on which machine I want to run. Is there a better way?... Post, WCS, Two separate files, etc. All ideas welcome. Thanks Keith

Is there another way to force the A axis positive? I think I'm rotating fron A pos to A neg. I want to rotate to B 180 to machine the other end.

Top for all, both ops are curve 5 axis, with lines for tool axis and collision control.

Thanks for the reply. The problem I'm seeing is the A axis should be ~90. for both cuts. I can't figure where the A120. is coming from. It should be a simple tilt A to 90. make the cut, retract, rotate B to 180 and cut the other end. Keith

Hi all. I'm getting an "ERROR-THE TOO; CAN NOT BE POSITIONED WITHIN MACHINE ROTARY LIMITS" error. After I OK the error, it posts the folllowing. G0 G54 G90 X2.5645 Y-5.7055 B49.495 A90.028 S2500 M3 G43 H1 Z4.5787 Z1.0787 G1 Z.5787 F20. X2.4556 Y-5.8732 X2.0338 Y-6.5229 Z1.0721 F10.

A 120. is the limit. I know it's something simple. I just can't see the forest for the trees. Please help Thanks, Keith

I'll dig into the books to find out if/how to set the parameter from the program. Thanks for the idea.

Hi all, does anyone know if it is possible to completely disable the B axis on Haas VF6TR by nc command? I have a fixture that will crash if the oerator jogs the B axis. I'd like to rotate to B 180. then disable B so that if the operator hits reset, then jog, the B will not move untill the reactivate command at the end of the program. Any help or ideas? Thanks Keith

Yes, PCD is conductive, so you can cut it. It's kinda cool. I'm currently using E-Pacs I got from Mits, one rough and one skim, but they show slight surface erosion on the top face. I'm hoping there is someone out there who might be able to help me eliminate that erosion. Thanks

It's been a while since I've posted here, glad to be back. I'm looking for advice from the Mits Wire EDM Experts among you. I'm trying to resharpen PCD lathe inserts on our FX-20. Any advice on which E-Pac to use for a starting point, number of passes, tricks, tips, etc. would be greatly appreciated. Thanks Keith

Hi All. Please help a rookie. With MPW-FA10.pst(updated from v-9) when I set MI1 to 2 "I want a G54" the nc output is: % H1 =.0067 N1 G90 N2 G54 X0. Y0. N3 G00 X0. Y0. N4 M20 etc. I want: % H1 =.0067 N1 G90 N2 G53 G92 X0. Y0. N3 G00 G54 X0. Y0. N4 M20 Where do I start? Thanks, Keith

Our rule of thumb is; "If the part extends more than 1 1/2 times the chucking diameter, it should br supported with a center or steady rest." This rule does not cover all of the variables. ie. Step jaws. soft jaws, pie jaws, material etc. Anyone have a better rule? Thanks. Keith

Eric, I wish that all would remember to turn the override back off after set up, but I have to admit; I've forgotten myself.

This whole thing is over an operator overriding the door hold so he could run with the doors open. It cost him a trip to the doc. We want to turn the interlock on at the start of every NC file. That way if the interlock is overriden for set up, they can,t forget to turn it off. Hope to save the next guy that trip to the Vet. Thanks

OK. I guess we'll have to figure out another way. Thanks.

sOK. Thanks anyway.

Hi All! It's been a while. Anyone know if it is possible, on a Haas mill, to togle the door hold override on/off in the NC program. Thanks Keith

Got it! Ended up with Micro 100 .4 MM ball mills at 30k RPM, .0007 peck at .45 IPM. Because the carbon cloth was at a 20 deg. ply angle, the BEMs tended to follow the ply. We had to peck down to -.17, then re peck from 0 to -.24 in order to keep the holes straight, they had to meet in the center of a .5 in. round to make a through hole. The last op is re peck to -.27 with a .4 MM Harvey drill the BEMs were breaking. Thanks for the help. Hope this will help someone else in the future.

Thanks Kevin, Onsrud only goes down to .125 I have to head out for the day. I'll check back in the A.M. Thanks

The reason for the ball mills is the .26 depth. We can't find drills with that length. The end mills have .03 flute length and a reduced shank for chip clearance. We have tried the #80 Harvey at .013 peck, they break on the first peck.
