Yes you will need a post if doing this on a 5 Axis machine. Reach out to your dealer. Biggest thing will be what direction do you face your right angle head when setup? X+ or X- or Y+ or Y- or is it a custom angle?

Ok thanks, I have a call out to them. As of now I am trying to figure out how to define an aggregate head in mastercam.

Hello gentlemen,

I need some tips on how to program the internal slots on this part, I need first rough out the slots then come back and finish them very accurately. The slot width parallelism needs to held within .0003". I currently program them manually now but it becomes challenging when the slots are not linear. We are machining them on a haas with a trt210 trunnion.  Will I need a special post processor made? 

Thanks.

Numbers look good to me, albeit a tad conservative

What adjustments would you make? 

Does anyone use it here? Whats your thoughts on its feed calculations? We are cutting some 303 stainless using dynamic milling and the speeds it calculates are odd, the tool is a 1/2 4 flute from them. The chipload just seems way to high, only 2535rpm with 104ipm. Seems like they want me to buy more tools lol. Heres a pic of the calcs.

Thoughts?

Yes all you are doing it activating the control to map all the indexes and coordinates back the G54 and the control like many other controls is doing the heavy lifting in the calculations for you. Old school was way to program everything from center of rotation. Then you would teach your tools like a 3 Axis machine, but the post did all the work solving the calculations for the machine. With DWO/TCP now you program like a 3 Axis machine, setup like a 3 Axis machine and you are done. Problem is the disconnect in the process to do this. Trust me it was much harder to do 5 Axis than it is today with all these additions. Still not a point and shoot process, but if you think out the process correctly and go about everything the right way then you should be able program 5 Axis and Machine 5 Axis in today Manufacturing with a good bit of success.

awesome. Im going to program a part and activate the dwo option and try it out.

thanks for all the responses.

Think of it this way. Programming your 5 Axis like you would you 3 Axis for setup and workoffsets. The difference if you decide a place where you want your X Zero, Y Zero and Z Zero. You program you part there touch off your part there and done.

So when you add a g254 to the program do you still need a g54 offset tell the machine where the part actually is?

Could not think about a scenario where having dwo/rtcp/rpcp as a possibility in the control is a bad thing. If you don't want to use it just don't call their codes. If you need them, they will be there. 

From what it looks like I couldn't agree more. 

So Im trying to determine if using dwo would help us, we have a t200 trunion on our haas and we have been programing it to the center of the trunion.  I watched a haas video and it shows you just need a coordinate on the top of the part in mastercam, im assuming a fixture offset is needed from c/l of the rotary. anyone here using it? any suggestions?  It sure looks like it would really simplify things.

Thanks.

heres the vid,

Just wanted to thank everyone for their help. I would love to keep playing with this but I have to get this machine running. I put an order in for a post yesterday.

Try:

rotaxis1$ : -vecy

rotdir1$  : vecx

that didnt work either. any other suggestions im open. thank you

The Generic Fanuc 5X Mill Post (on which your Post is based), will not just rotate the C-Axis Platter. So if your Platter is facing "up" towards the Spindle, there is no logic to simply rotate the C-Axis.

If you are having issues with the C-Axis not being correct, while the B-Axis is already at 90 degrees, then you likely need to rotate the "Primary Axis" (C-Axis) vectors.

Try changing this:

rotaxis1$ : vecx

rotdir1$  : vecy

To this:

rotaxis1$ : vecy

rotdir1$  : -vecx

That didnt work, my b90. should be b-90 and my c should be c-90. Any other suggestions? All help is very appreciated. 

If I have sequences that just move the b axis or b/c it posts good, once I move the c axis by itself it causes my issue.

is it something in this area of the post? is my tool mapping off?

I tried changing them to this with no luck. If I change secondary axis it just rotates the c axis in one direction.

I tried playing with them with mixed results because Im not sure really what im changing. Its defaulting to these varibles,

Did you try activating "force tool change" checkbox on op #9 ?

C^Millman gave me that tip in 2007

Well that actually worked but I cant have the machine do a g28 for every new rotation, is it a post issue or something im doing in mcam?  Thats the million dollar question lol.

thanks so much! 

So Im having an interesting issue, if I post a sequence individually it posts the b/c correctly, but if I post multiple sequences its not rotating the c axis correctly. Its trying to force a b axis move. Im assuming I need to change something in the post? Look at sequence #8, its at b-90.c-90.  Sequence #9 next should be rotating to c90. but its trying to go to b90. instead.  Btw, seq 7 thru 11 only have the correct wcs and t/c plane. I still need to change the other sequences once I get this fixed. Time for a drink lol.

thanks guys!

Try this settings.

# 5 Axis Rotary Settings
# --------------------------------------------------------------------------
#Assign axis address
str_pri_axis : "C"
str_sec_axis : "B"
str_dum_axis : "A"

I think that worked.  My next post for our fadals will be made by in-house, I have the quote already. 

thank you very much, I will update on how everything works.

That is a B/C setup

Tilts around the B rotates about the C

Don't fall for the old Haas AB setup.....everything with Haas was AB,,,,,,I just went through this with a contract customer....he had an AC set up...it ran as an AB but to get his Dynamic Offset to work properly, he had to go back in a set it up properly an an A/C

 

Well you are correct it is b/c, the dynamic work offsets wont work if I configure the machine to a/b. So my question is how do I change the axis destination in my generic post?

B needs to be tilt and C needs to be rotary. 

thanks for all your help guys, I really appreciate it.

Thanks for the info, Colin. The prepped stock would have pretty loose tolerances (±.03) as it would be just to eliminate the need for a dovetail OP for raw extruded aluminum, out of which the final part would then be cut. I could incorporate the dovetailing OP into my procedures, but I'm also looking at cost/benefits so getting prepped stock may have saved some money on each part. I'll have to let my managers decide if the time savings is worth any extra cost.

I will keep them in mind for future projects, though. We make a lot of custom fixtures so having some nicely prepped blanks that are flat/square within tight tolerances would make all of that much easier.

We use tci all the time but it would still be cheaper to buy rough stock and prep the dovetail yourself. You should be dovetail prepping the material and finishing the part in the same op. It shouldnt take anymore than a minute to cut a dovetail and slot, add in a program stop and load the part into the raptor. After the 4 or 5 axis work is done that part could go into another vise in the machine and machine off the dovetail and complete the part. You will have finished parts coming off the machine which saves time, inspection of multiple ops and less chance of scrap.

Change the sign of rotdir1to + or -.

rotdir1$ = -vecy #Direction    This is for your primary axis              

Secondary axis is rotdir2$

Looks like its ok now, I will keep playing with it.  Thank you for all you help.

well this is interesting, the rotary on a haas trunnion is the B axis and the tilt is the A axis.  So the only thing I need to fix is the direction of the B axis, I drilled a hole a B90. and it posted it as B-90. How do I fix that in the post?

our fadals are set up as A B like the video, so im assuming it would be  A/C if the trunnion was set up different than the video?

Im trying to create a program for our new Haas vf4 with the TR200y 5 axis rotary table (trunion). I believe the generic pp thinks the rotary rotates about the X axis, we are setting it up to rotate about the Y axis and tilt about the X axis. Is there an easy way to edit the generic post?  Thanks.

Ok, I think the way I worded this was incorrect. We need the rotary (A axis)  to rotate about the x axis and the tilt (B axis) to rotate about the y axis, I had it backwards. We are mounting the tr200 just like in this video.  When I post my program its posting the A axis as the B axis. X and Y is posting correctly.  Thanks guys.

Never mind. Found it in an older post about the same topic. It was in the post and not the machine definition.

 

brk_mv_head  : 1     #Break the 5 axis moves to remove gouge

brk_max_ang  : 180     #'brk_mv_head' maximum angle move, applied if chordal_ "was 1 changed to 180"

 

Fixed the issue

sorry for the old thread bump but this was very helpful and fixed my issue on the rotary axis (A axis), now do I need to fix the B axis?  (tilt)? 

this is a haas tr200y, Im editing the generic haas post.

nsk america, this will be your cheapest option but you will need some sort of adapter to your main head. We use tecnara and they make an adapter.
