# Real 3D Cutter Compensation...

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.
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=.

FOR 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 problem has long been solved by us for all CNC systems.

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

Toolpath for "original" tool D12R6

2. CSE-simulation nc-programm for original tool

CSE-sim for original tool. You can see real tool radius and nominal tool radius.

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

For tool D20R2, same nc-programm
4. For tool D40R0

For Tool D40R0
