The reverse bore types supported are:

Reverse Bore  

The tool is fed to defined depth at the controlled feed rate; the spindle is stopped and then a rapid retract is performed.  It is then stopped to orient the spindle, moved away from the side of the hole and finally retracted.

User Defined Bore1 / User Defined Bore2

Defined using the Post-Processor Generator for your selected post definition.

RBore Depth - Enter the depth for the current drill operation.  You can select the Pick button to pick a point on your part model that defines the drill depth.

Select this option if drilling should start at your Work Zero.  The Drill Depth is then subtracted to this location.  An actual point is not required.  The location is determined automatically by your Work Zero location.

At Top

Select this option if drilling should end at your Work Zero.  The Drill Depth is then added to this location.  An actual point is not required.  The location is determined automatically by your Work Zero location.

At Bottom

Project to 3D Model

Select this option if you want to project the start point to your 3D model.  For example, if your stock is longer than your part but you want the Drill Depth to begin at the face of your part instead of the face of the stock.  An actual point is not required.  The location is determined automatically by your part model.

Project to 3D Model

Select this option if you want to specify the coordinates of point where the drilling should end at your Work Zero.  The Drill Depth is then added to this location.  An actual point is not required.  The location is determined automatically by your Work Zero location.  You can select the Pick button and then select a point on your part.  It's coordinate will be calculated automatically.

Dwell is an optional parameter that allows a machine delay of either Time (sec) Rev (rpm) of the spindle.

You can define the Approach Distance under Engage/Retract. The tool rapids in the Z axis to the approach plane and then applies the specified feedrate from the approach plane to the specified depth to perform the cycle.

Using the Reverse Bore types (see above), the tool is fed to the specified depth at the controlled feed rate. It is then stopped to orient the spindle, moved away from the side of the hole and finally retracted. Use this parameter to enable Tool Orientation and enter the value in degrees.
