Cut Parameters tab, Drilling, 2½ & 4 Axis

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

The following drill cycles are available

drill-cut-parameters

Standard  
Used for holes whose depth is less than three times the tool diameter.

drill-deep-cut-parameters

Deep  
Used for holes whose depth is greater than three times the tool diameter, especially when chips are difficult to remove. The tool retracts completely to clean out all chips.

drill-csint-cut-parameters

Countersink  
Cuts an angular opening at the end of the hole.

drill-break-cut-parameters

Breakchip  
Similar to Deep drilling, but the tool retracts by a set clearance distance.

User Defined Drill1 / User Defined Drill2  
These are user defined drill types.
tog_minusDepth Control

Drill depth refers to the hole depth. It needs to be specified for Standard, Deep and Breakchip drilling. Selecting Add Tool Tip to Drill depth is used to drill through holes where the height of the tool taper is computed and added to the drill depth.

tog_minusLocation of Drill Point(s)

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

The following additional parameters are supported:

Counter Sink Dia.  

Required only for the Counter Sink Drill Type operation. The system will automatically calculate the drill depth. Optionally, you can use the pick button to select a circle to define the diameter of the Counter Sink.

Step Increment  

Used to set the peck increment tool. This needs to be specified for Deep and Breakchip drilling. The tool retracts after each step increment completely to clean out all the chips.
