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.

All your time greatly appreciated. One last question. After you get one tool path, what would be the most efficient way to do the 7 other groove's ? Transform the tool path's & re select the geometry or maybe another way ??

I would transform them.

Depending on the machine it may be better to use a sub program. But getting that to work with Post Builder requires some customization and Tcl.
