How to program a tool that mounts on a manually indexable head?

Creator

Hi.

 

I need to program a square shoulder mill which mounts on a manually indexable head and the control point (tracking point) should be at the lowest point of teh cutter after it is indexed.

This is a roughing operation and has to work with a 'workpiece' geometry.

 

Thanks in advance!

Is this like a right angle head but you can rotate the tool as needed?

 

If so you will need to add a Head object and then have the tool as a child of the head.

 

You will need to set the unit vectors for the direction from the spindle axis.

Hi camster. Thanks for your reply.

I did try to define a head and a child tool. The tool path generated by this tool was no different as opposed to the tool path produced by the same tool without the head.

I need NX to recognize the effective cutting shape of the tool in that orientation and calculate the tool path.

Hello Camster,

 

I have this configuration.

But I don't know, how can I load the 3D head object on this tree. With proper configuration I could see the head, holder and the cutting tool, all 3D models on NX CAM.

When you create the tool path does the tool axis match the vector? Is this s fixed axis operation of variable axis?

You are right, this is a fixed axis operation of a cutter on a pre-fixed tilted and rotated tool axis. When I create the tool path the tool axis was set to 'Z' axis. I did manage to get the tool path by using an alternate method - but I need to know how to do this in an automated operation in NX.
Thanks for helping.
