Cut Parameters tab, Reverse Boring, 2½ & 4 Axis

The Reverse Bore parameter settings are similar to the Drill parameter settings and are used to form shapes inside of a hole.  The following dialog allows you to set the Cut Parameters for Reverse Boring operations.  

You can set the Reverse Bore Type, Depth Control, Location, Dwell and other parameters via this dialog box.  Just as in the drilling operation, User Defined Reverse Bore cycles can be created by selecting User Defined RBore under Reverse Bore Types.

tog_minusReverse Bore Types

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.

rev-bore-cut-parameters

User Defined Bore1 / User Defined Bore2

These are reverse bore cycles that you can define using the User Defined Cycles in the Post-Processor Generator.
tog_minusDepth Control

Bore Depth refers to the hole depth.
tog_minusLocation of Cut Geometry

Select from the following for Location of Drill Point(s):

At Top  

This uses the Z location of the selected Control Geometry as the top of cut. The generated cuts will start at this Z location and cut down in Z to the specified total Drill Depth.  At Top is typically used when your hole diameters or drill points are at the top of your part.  

At Bottom  

This uses the Z location of the selected Control Geometry as the bottom of cut. The generated cuts will be above the selected machining region and last cut would be at the Z location of the specified region. At Bottom is typically used when you select the diameter or drill points are at the bottom of the hole.

Project to 3D Model  

This option projects the selected the Control Geometry to the underlying 3D geometry.  

Pick

PickThis allows you to specify the Top of Cut for the selected Control Geometry and is typically used when the selected region is not at top or bottom of the hole. The generated cuts will start at this specified Z location and cut down in Z to the specified Drill Depth. This would be useful when the selected Control Geometry is at the bottom edge of a fillet or chamfer.
tog_minusDwell

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

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

Tool Orientation  
Using the Nodrag Bore Type, 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.
