Automated Drill: Tool Trajectory Parameters

The Tool Trajectory - Automated Drill parameters are displayed. Depending on the Drill Type you have selected (in the Tool Trajectory table), some parameters may be displayed and others may not be available.

Numerical formulas can be used for a number of Automated Drill parameters, for example; Top Delta, Delta Retract and Bottom Delta. See Formula Expressions for additional information regarding the formulas.

The Automated Drill parameters are explained below. Specific parameters are displayed for the following Drill Types:

Spot Drill	Thread Milling	Gun Drill
		See the additional Gun Drill parameters in the Machine Parameters Table.


Pocket	Profile	Helical Profile

General Automated Drill Parameter explanations:

Changes to the parameter settings here, also change the displayed value of the relevant parameters in the Cutter Sequence Data table.

See Internal Thread Milling and Pocket, Profile, Helical Profile for related parameter explanations.

Opposite Direction

Select the Opposite Direction checkbox to enable drilling both sides of a through hole, using only one sequence.

The image below shows two drills positioned on both sides of the through gun drill hole, executed in one sequence.

The ability to drill a hole from two sides (in a single procedure) is dependent on the following conditions:

The hole must be a Through hole (not Blind).

The machine can access it from both sides. This is dependent on the Max Inclination Angle and the access above each side of the hole. If the angle is set such that a through hole can be drilled from both sides, then the Opposite Direction option is available.

When the Opposite Direction checkbox is selected, pick the drilling reference points to reflect the opposite direction. For example, in the image on the left, to milling the C segment, set "Top Reference" as C and "Bottom Reference" as B.

Notes:

When working on 4/5X Automated Drill, the Group Manager distinguishes between through holes that can be drilled from 1 side and holes that can be drill from 2 sides. The Group Manager separates those 2 types of holes and puts them in different groups. This allows the assigning of different sequences to such kinds of holes.
When the Opposite Direction checkbox is selected, an icon is added to the sequence definition in the Cutter Sequence Data table, indicating the opposite direction drilling.
Use the MD anchor point to program drilling half way through from both sides.

Top Reference

A reference anchor to the drill start point. This reference point can be set in the following ways:
- Graphically
- Dropdown List

Graphically: Right-click a reference point in the graphics area and select an option from the list to define the point as either Set as Top Reference or Set as Bottom Reference.

Dropdown List: Select the reference point from the adjacent dropdown list containing the anchors. The default anchor is DP.

Graphically: Right-click the reference point and select the reference option:	Dropdown List: Select the reference point from the adjacent dropdown list of anchors:

In either case, the reference point is changed for the selected parameter.
The initial parameter setting:	The parameter setting after DP was defined as Set as Top Reference:

The procedure for setting the Top Reference and Bottom Reference points is identical.

See Using the Cutter Preview.

Top Delta

Delta from the Top Reference to the actual point were rapid motion changes to feed. See Using the Cutter Preview.

Delta Retract

The incremental distance above the drill reference point where the cutter motion changes from the Rapid Feed rate to the Feed rate during the approach.

Bottom Reference

A reference anchor to the drill end point.

The procedure for setting the Top Reference and Bottom Reference points is identical. See the explanation for Top Reference, above.

See Using the Cutter Preview.

Bottom Delta

Delta from the Bottom Reference to the actual point were the drill ends. See Using the Cutter Preview.

Bottom Type

A geometrical definition to calculate the actual tip location at the bottom. This is a dropdown list containing the following options: Cutter Tip, Full Diameter and Chamfer Diameter.

If Chamfer Diameter is selected, the Chamfer Diameter parameter is displayed:

Chamfer Diameter

The cutter reaches the selected depth at the chamfer diameter.

This parameter is only available if Bottom Type = Chamfer Diameter. The default value is 0. See Using the Cutter Preview.

Shift

This is the same as the Shift parameter for normal Drill operations.
If the Shift parameter is selected, the Shift I and Shift J parameters are displayed.

Dwell

This is the same as the Dwell parameter for normal Drill operations.
If the Dwell parameter is selected, the Time parameter is displayed.

Peck

This is the same as the Peck parameter for normal Drill operations.
If the Peck parameter is selected, the Step and Decrease parameters are displayed.
