Setup Properties > Zero

Use the Zero tab of the Setup Properties dialog to select a method of specifying part program zero and to translate the location of the Setup. The part program zero is the origin of the coordinate system for the NC program.

Select a method for specifying the part program zero from the drop-down list.

• Align to Stock Face — Select this option if you want to align the Setup with the center or corner of one of the Stock faces, or to explicitly pick a location.
• Align to Index axis — Select this option to align the Setup with the index axis. (This option is available only for a turn/mill or 4th-axis indexed part.)
• Align with existing UCS — Select this option if you want to align the Setup with a previously created user coordinate system (UCS).
• Align to part geometry — Select this option if you want to align the Setup relative to the part geometry.

If you want to translate the location of the setup, enter the amount to offset the Setup in the Additional Offset area. One reason to translate the Setup is to model the extra stock on top of the part that is removed during a facing operation. You may also want to translate it to a location that you cannot easily snap to.
