We program a Fidia control, but as you said...the post is the key issue. Our standard is an .APT(with a custom post) or NCI file out of Mastercam and a second party post processor. For the most part, it seems pretty simple like the ideal is just to feed it point to point data, so I don't know that a direct post out of Mastercam would be all that difficult.

 

If the machine is a Nutator head (A & C axes) with a limited C rotary then the logic needed would be difficult to handle the rewind in full 5-axis motion. That is the primary difficulty with our setup. Requires programming it a certain way then detecting rotary overtravels and going back and changing it.

 

I don't think this scenario would be any different with any other CAM package though.

Hey mls I'm having some programming drama's with our new Fidia . Have you got much know how on Fidia plane shifting "G21 RX RY RZ VX CY CZ " ? 

Totaly agree feel like i have been trudging through mud for a few weeks now , Yesterday had a full 10 hours of productive time and good breakthroughs  feeling quite chuffed.

I'll keep you updated on how i get on  but I think we have (this issue at least ) licked

yea i get that had a good win today, i think it may be post related  output a similar function and the plane shift line had the same specs as the sample I posted but the b and c moves where wrong B-15 {should of been B15} and C180 {should of been C0}.

but then on another example of the same procedure just on a different plane it appeared correct. in the first instance I corrected the B and C moves and it ran fine. {haven't proven the second and third instance yet} So i guess I'm going to keep building an information bank to give postabilaty a fighting chance of working out a viable edit. 

so I tried  plenty of different setups with the G21 and only got worse results, it appers only one axis is being rotated  and from what I read in the programming manual the code should be right. I'm wondering if it's a control setting or parameter may not correct, that's why I'm trying to find some Fidia guru's to pick there brain.

Fidia have been great for tech support but with the time zone and language difficulties i thought I would cast a wider net.

in relation to the kinematics will my machine def have a bearing on that ?

yea for the most part. the learning curve is flattening out a little  still heaps of head scratching going on as i don't have anyone in the shop to teach me. And to make it harder I keep getting all the  curly " that will easy as on the 5 axis" job's

any of you  5axis guys got any feedback about this one

Hey guys any of you got any experience on Fidia C10 Stuff ?.
We have a retro fitted Okuma 5 axis with a c10 and I'm just looking for a few guys with a bit of a knowledge base to help me out. I have got 90% of my day to day and regular driving sorted out and quite happy ..... but I do still have a few questions, and when I do get stuck it can be a real grind trying to find solutions as there is not a lot of practical solution's to be found online.

The main issue I'm having at the moment is with my  g20 g21 program rotation doesn't seem to be working correctly. the rotation of the plane shift shows up in the ROTANG {program rotation} dialog screen but when  the program runs the axis shift doesn't seem to be correct.

I'm not sure if the plane shift and following code @N270  are correct ? i would of thought the Y would stay the Y and X and Z would be switched?.

Could one of you more worldly gent's please take a look and help a brother out.

I have added a zip2go of the file the tool path in question is the 90 deg facing cycle towards the end of the part.

Thanks for all the feed back guys the only issue was with my re-seller getting the info through. we have got some great traction now that our edits are getting  to postability, every edit has fixed every issue we have had so far. big up's 

We ran into axes inverted with postability's okuma 5x post. We turned off tcp in the post which is for head head machines and that corrected the problem. I was disappointed with documentation that came with that post.

I to have been really underwhelmed by our service too. we pay top dollar and get bugger all and made to feel that we are lucky to get what that. 

e-mailed prosoft (our rep) friday morning about the issue got a reply late Tues. 

The reply didn't even relate to the post question! i only got a hard sell on some mastercam-u papers. so frustrated  

is any one here versed in FIDIA code ? 

Sweet guys I'll see how I get on :-)

What about dialing up tool paths do I have to use multi axis or can I use regular toolpaths? Do you have to use the "convert to 5axis".

Yea nice thanks, I thought as much.

So for that stuff would you just set up a plane as I have and just for arguments sake do a peel mill and set wcs top, T & C set to plane XXX ?

Hey guys been slamming mastercam for a while on 4 axis stuff no drama's. We have just got a new to us okuma 5 axis vmc. It has 360 deg table turn © and pivot head (. I have been playing with this part without any luck could one of you 5 axis guru's give me a bit of an in sight on how I might program the slot's on  this part ? one of the most confusing issues is that my X and Y moves seem to be around the wrong way when I post ( this may be a post issue )? I am putting the heat on my boss to get the multi axis training from mastercam, Dose anyone have any feed back on that also?   Any information would be great thanks guys

Hey guys just setting up our new okuma post looks ok so far. But on tool calls it outputs  M6 T.1 . how can i remove the . before the the number is that a master cam setting or a post issue ?

I stand corrected,   thanks a lot for your help man 

Hey guys i'm setting up a roughing cycle with opti rough and can't get it to see any stock got me stumped ?? 

could some please have a look and see if they can see what i'm doing wrong. I have done this type of stuff countless time's but seem to be stumped 

WELD TEST.mcam

So I got some mean as action with my wrapped tool path though I would put up a we clip.

Following

So if you're toolpathing the outside your chain should go clockwise for climb milling and opposite for inside.

As for sides and direction you'll see your geometry section of you're operation? click on that and a dialogue box opens showing your chains/points. If you right click on a chain it will give you a bunch of options.

Change side reverse. Start point Ect, ....

yea I worked that out by myself about 45 mins before knockoff . where I was going wrong was in the un-rolling of the geometry . ended up roughing out the center in a lathe and using a dynamic contour to finish the cam profile.

Sim looks good and computer say's yes so wait and see if the result is correct

1] didn't realize i had to un-roll geometry 

2] made another solid with an more tool path friendly transition at the direction change of the cam, i then came back and used a 3D hybrid to tidy up the bit's I couldn't do int the wrapped dynamic contour.

cheers for the help guys

Ahh. 

I just wasn't familiar with that link. 

Good to know!

Ha yea sorry should of said couldn't upload the .mcam file for some reason ?.

Cheers for the help I cracked it about 45 mins before seeing this, plan ended up being roughing the center in a lathe and using dynamic contour and 3d hybrid on another plane to grab the little bits I couldn't reach with the contour. I'll post up a vid when I run it. Been reassigned to a most important rush job for now.

Can any of you fine gent's please help me with a tool path that i could use to finish the walls of the please best i could do is a roll die but that still miss's bits. is there a milti axis function i could use with a ball nose ? i'm not really very educated with multi axis toolpaths.

I have a 3 axis vmc with machining 4 axis fanuc oi-m control

below is a link to the .mcam file  for some reason it wouldn't let me upload

Oh true I feel the same . Didn't know that, I've only been on mcam since x7. 2017 looks good otherwise to me :-) thanks guys

Ok Cool Thankyou very much.

Is it just me of is that a bit naff ? seems like a backwards step from the yellow box's where you could dial up a calc or lock on an x,y or z value or right click for other options ect ? I take it there is not a setting to bring that back.?

But there is no display for it  ? when i type an empty dialog box comes up ? do i go x... {tab} y... {tab} ect ?
