When a HELICAL MILL hole canned cycle is selected on the Cycles Data or Edit Cycle dialog, the following settings are available on the Edit Hole Operation dialog:
Hole Canned Cycle — This field displays the name of the hole canned cycle selected on the Cycles Data or Edit Cycle dialogs.
Helical Step Defined By — Select how the step is defined:
- Pitch — Select to define the step by the pitch of the helix. The Pitch (p) field is displayed in the Depth area.
- Angle — Select to define the step by the angle of the helix. The Angle (A) field is displayed in the Depth area.
Hole Diameter (D) — This field displays the diameter of the hole. The value is taken from the Hole Diam field on the Cycles Data or Edit Cycle dialogs.
Tool Diameter (d) — This field displays the diameter of the tool. The value is taken from the Tool Data or Edit Tool dialogs.
Depth (H) — This field displays the depth of the hole. The value is taken from the Depth field on the Cycles Data or Edit Cycle dialogs.
Pitch (P) — Enter the pitch of the helix. This field is displayed only if Pitch is selected in the Helical Step Defined By list.
Angle (A) — Enter the angle of the helix. This field is displayed only if Angle is selected in the Helical Step Defined By list.
Number of Spring Passes — Enter the number of clean-up passes taken at the bottom of a hole.
Retract Type — This field displays the retract type. In a HELICAL MILL hole canned cycle, the tool retracts completely out of the hole after each step.
Retract Motion — This field displays the retract motion. In a HELICAL MILL hole canned cycle, the tool makes a rapid move when it retracts.
Output Hole Canned Cycle — This option is selected by default so the machining operation for the hole is output as a canned cycle in the NC Program file. If your postprocessor does not support all of the parameters for this canned cycle, deselect this option.
Index Broach Options — This option does not apply to this cycle.
