NX What Origin Should the X, Y, Z, etc. Dimensions Reference in a Generic Feature Operation

In NX1899 a new type of operation was added to the Holemaking menu. This new item is called the Generic Feature Operation. In this operation the user is allowed to create a series of tool moves that will be performed at every hole location in a geometry group. When creating this type of operation what origin is referenced when adding the X, Y, Z, etc. motion?

Solution

In the example below the utilities Find Feature and Group Feature are used in the Machining Feature Navigator to create a geometry group named FG_STEP2HOLE. The origin and tool axis are reversed in order to machine from the preferred side of the Workpiece. When the FG_STEP2HOLE group is selected the Feature CSYS of each hole is displayed. This origin is the point from which all tool motion is measured.

How this origin works can be seen by creating a Generic Feature Operation and adding Sub-Operations.

When a Circular Move Sub-Operation is added the X Axis and Y Axis values are both zero. These zero values indicate that the center of the circular move is on the Feature CSYS which is the center of the hole.

When a Linear Move is added all motion is, again, taken from this same Feature CSYS. In the example below the X and Z values are output as a distance from this origin. The dimensions of the hole features are read from the part model using the Function option.
