Select the Define Cycle button to open the Define Cycles dialog.
Select and enter appropriate criteria to define a drilling cycle(s). Refer to the Parameters table below for more information on the Define Cycles dialog parameters.

Parameters

Bottom Delta

Enter the value to shift drilling below the reference points (refer to the definitions for Top Reference and Bottom Reference below).

Bottom Reference

Reference point that defines where to finish the drilling operation.

Coolant

Define the coolant type to be used in the drilling cycle. The available options are listed below (standard options); however, the Coolant pulldown list may also display up to six (6) additional user-defined coolant types that have been previously defined in NC Preferences

Coolant Off	No coolant is used in the drilling cycle.
Flood	Flood coolant is used in the drilling cycle.
Mist	Mist coolant is used in the drilling cycle.
Through	Through-tool coolant is used in the drilling cycle.
Air	Air coolant is used in the drilling cycle.
Multi	This option is displayed in the Coolant row when two or more coolant types have been selected.
