Good evening!

 

I spend few days with paper and pencil, but now I have a magic formulas for real 3D Cutter Compensation.

Just see a video.

Wow

This is a really good enhancement. In our case we only can add a correction ln a 4 axis toolpath with changing the tool in NX.
Your NC code adujust also the geometrie of the tool. Awesome
How does it handle a Ballmill?
Keep going

Production: {NX 10.0.3.5 MP18}
Testing: {NX 12.0.2.9 MP03}

I see you have a Sinumerik controller. You can use the function CUT3DF, it will exactly do the real 3D cutter compensation. 

Use "Contact output" in ther "non Cuttings".

Get the correct mom_variables, for the contact points write X Y Z, for the face normal vectors A5= B5= C5=.

3dcomp.pngFOR BallMill Tool

And for BallMill tool (if you use Ball Mill Tool only) NC record will be more short and not so complex.

 

 

@Bernhard_Swiss - for BallMill working exactly a same, in this case Nose Radius = 0.5 Tool Diameter. Like EndMill Tool with zero NoseRadius, Ball Mill just not ordinary case.

 

 

 

@Professor - I know about CUT3DF. But sometime for SINUMERIK it is a option. And I use my formulas for FANUC (MAZAK).

This is the result of the machining CUT3DF function and the simulation CUT3DF function.

Morning!

I have tested 3DComp on real metal.

 

1. Toolpath calculated for BALLMILL Tool D12R6

3DCOMP_1.pngToolpath for "original" tool D12R6

2. CSE-simulation nc-programm for original tool

 

3DCOMP_2.pngCSE-sim for original tool. You can see real tool radius and nominal tool radius.

3. For tool D20R2, and you can see recalculated toolpath.

3DCOMP_3.pngFor tool D20R2, same nc-programm
4. For tool D40R0
