Cut Parameters, Tapping, 2½ & 4 Axis

The following dialog allows you to set the Cut Parameters for Tapping operations.  You can set the Tap Type, Depth Control, Location, Dwell and other parameters via this dialog box.

tog_minusTap Types

The tap cycles supported are:

tap-std-cut-parameters

Standard Tap
This is a standard tap cycle.  Move to XY, Move to Z at approach distance, tap to depth, retract to clearance.

tap-peck

Peck Tapping  
This is a peck tap cycle.  Move to XY, Move to Z at approach distance, tap to peck depth, retract to top of peck, tap to peck depth, repeat to until full tap depth, retract clearance.

User Defined Tap1, 2, 3, 4  
This is a tap cycle that you can define using the User Defined Cycles in the Post-Processor Generator.
tog_minusDepth Control

Refers to the tap 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_minusTap Direction

Allows you to select between Clockwise and Counter Clockwise tap.  Selecting Right Hand Tapping creates a clockwise tap and Left Hand Tapping creates a counter clockwise tap cycle.
tog_minusCut (Peck) Depth

This is used to set the peck depth increment.  This needs to be specified for Peck Tapping. The tool retracts after each increment completely to clean out all the chips. Note that the Peck Taping cycle (G84 right-hand, and G74 left hand) needs to be defined in your post-processor.
