Need help: 5-axis generic post edit - Rotary axis shift (offfset)

[Giang-TT]

Hello,

I have a  5-axis table-table machine. A for X and C for Z. In my machine, the A-axis center line does not intersect with C-axis centerline (it's about 1mm offset). I've tried to edit "saxisy" value in  the post but nothing change when the code generated.

I've tried on both post "Generic Haas VF-TR_Series 5X Mill" also Generic Fanuc 5X Mill"

Anyone can help me to solve my problem.

Thank you,

Giang

 First you share information in your video on youtube, then you ask questions   ?

Sorry, that's just a document for sharing. I have tried but it still not work. So I ask if someone can help me. Maybe I missed something in the post.

I don't see the table offset in the Post. It must be locked up in the PSB.

 

If your machine has Tilted Workplane (G6.82) you don't even have to worry about programming relative to center of rotation. I program 5-Axis all the time and my programs are either written from an arbitrary position on the stock or relative to part coordinates.

 

Just a thought.

Booyah G68.2 that's about 98.713% of my work. All this time I thought I was the only one. Most people don't even get how it works. For 5 side machining you can't beat it. Throw that part any where on the table, probe for C then probe it like a 3 axis mill and start ploughing.

 

You ever use 68.4? You running that in a Mazak or a Fuhnook powered something?

My old machine does not support these function, so I need to declare everything exactly in my post. This is where I make change in the post:

saxisx       : 0     #The axis offset direction?
saxisy       : 1     #The axis offset direction?
saxisz       : 0     #The axis offset direction?

What are you posting? 3+2, or 5X?

 

5X uses the 'nutating' shift. Not 'saxisx'.

 

3X uses the 'saxisx' variables. 5X uses 'n_saxisx' variables.

 

Also, test the 'r_intersect' and 'n_r_intersect' variables. If the shifts aren't happening, enable these.

 

Also, the 'mr7$', 'mr8$', and 'mr9$' variables are an 'incremental shift' for tweaking an individual tool path.

Hi Colin,

I decide to do a 5X posting, also tried with the "n_saxisy", 'r_intersect' , and  'n_r_intersect'    but nothing happened. Mastercam keep posting the same thing.

On FANUC 30i/31i Controls.

 

Never used G68.4 just G68.2 with Linear Values and Euler Angles. (Always 0 on the linears though).

I'm not sure in that logic in post.

it is best to align machine. or to solve that on control parameters.

 

in reality, I'm sure that there will be combination which that logic in post can't predict and it will go in wrong direction from what is in MC.

I use the linear all the time. I also use it for B0 C-any when I need to spin the table and get the rest of he part. You can only probe once and don't have to mess with G54.4.

Today I tried out with:

 

#Offset in head based on secondary axis relative to machine base.
#Normally use the tool length for the offset in the tool direction
saxisx : 0 #The axis offset direction?
saxisy : 1 #The axis offset direction?
saxisz : 0 #The axis offset direction?

 

And this works for 3+2 indexing using different tool planes.
