:confused:
I need to tool path this part in order to check my "A" axis rotation on my 4 th axis post I am buildng with PB. I have tried "contour area" with no luck. Thank's for any help .

Regard's,

Harold,

You need to us a multi-axis operation. I would use surface area or streamline as the drive method and select the floor face of the slot as the cut area. Set the tool axis to normal to drive and the projection vector to toward line, using two points at the center of rotation. This should give you A axis rotation.

What version of NX are you using?

That is tool path I used to get tool to follow the path of the groove. The other's you mentioned,surface area or streamline , produced weird result's, due to the lack of my understanding how to use them. I don't understand the part about "using two points at the center of rotation. " Do you mean picking a point at the center of the part at each end ? Excuse my lack of understanding . Thank's.

In NX the Tool Axis and Projection vector work togeter to get the correct motion. When you set the Projection Vector to Toward line one of the options is two points. So yes pick a point at the center of the part at each end.

You can e-mail me the file and I can take a look.
