Drilling to different diameters with stepped drills

Positioning Stepped Drills to a Specified Shoulder Tracking Point

 

Overview

You can now specify a tracking point on the shoulder of a stepped drill as the Tool Drive Point and specify a machining area from the feature to determine the drilling depth. This allows you to drill holes that are modeled slightly undersize with a larger tool.

Created with NX CAM 10.0.3

 

Details

Because this is an explicit action that drives a specified tracking point to a particular depth, the tool is allowed to cut the diameter of machining feature even when the diameter of the tool shoulder is slightly larger than the diameter of the hole. This behavior is desirable when holes are modeled slightly undersize or you wish to drill slightly deeper than the modeled depth.

Thank you

It's missing from the dialog, and will be fixed. 

For now, you can add it yourself - select the tool, right mouse, object, customize.

Select Corner Radius in the lower list, Flute length in the upper list, and then Add to Dialog. 

To fix it for all new tools, open the hole_making template part, and customize the STEP_DRILL.
