There are 4 possible ways to do horizontal boring operations in Router-CIM with a Boring Block.  There is a drawing attached to this tutorial as a sample and there is a knowledge for each one of the 4 methods.  This document will explain how they would work on the machine.

The drawing has holes on each side, and for horizontal boring you must draw the circle on the correct Face of the part.

To help you with this, Router-CIM has 4 UCS commands to help fix the UCS on the correct Face.

The FS command will ask for the origin point (lower left corner) of the Front side of the part.

The RS command will ask for the origin point (lower left corner) of the Right side of the part.

The BS command will ask for the origin point (lower left corner) of the Back side of the part.

The LS command will ask for the origin point (lower left corner) of the Left side of the part.

If the parts are not drawn on the correct face, the machine will not cut them properly.
