CAM Drilling

Description

The Drilling tool generates a drilling Operation in the Job.

Usage

1. There are several ways to invoke the command:

   • Press the CAM Drilling button.
   • Select the CAM → Drilling option from the menu.

2. In the Operation section:

   • Select a ToolController.

   • Select a Coolant Mode.

   • Optionally enable and adjust the following:

     **Peck**
     
     set the **Depth**.

     • Dwell

       set the Time in seconds.

     • Extended Depth

       .

3. In the Base Geometry section confirm that the list matches the holes that are intended for processing, and adjust add, enable, or disable, as necessary. Holes can be added by selecting the wall faces of the Holes.

4. In the Depths section check, and if required adjust, the Start Depth and Final Depth.

5. In the Heights section check, and if required adjust, the Safe Height and the Clearance Height.

6. Press the OK button to generate the drilling path(s).

Notes

• When using edges for Base Geometry, always select the bottom edge of the hole.
• Always verify the tool chosen is the correct diameter for the hole(s) selected.
• Peck disabled generates (G81 canned drill cycles). Peck enabled generates (G83 canned drill cycles).
• Dwell enabled is currently unsupported, but is intended to generate (G82 canned drill cycles).

Properties

Note: Not all of these Properties are available in the Task Window Editor. Some are only accessible in the Data tab of the Properties View panel for this Operation.

{{TitleProperty|Base}}

Note: It is suggested that you do not edit the Placement property of path operations. Rather, move or rotate the CAM Job model as needed.

• Placement: Overall placement[position and rotation] of the object - with respect to the origin (or origin of parent object container)

• Angle

    : Angle in degrees applied to rotation of the object around Axis property value

-   
    **Axis**

    : Axis (one or multiple) around which to rotate the object, set in sub-properties: X, Y, Z

    -   
        **X**

        : X axis value

    -   
        **Y**

        : Y axis value

    -   
        **Z**

        : Z axis value

-   
    **Position**

    : Position of the object, set in sub-properties: X, Y, Z - with respect to the origin (or origin of parent object container)

    -   
        **X**

        : X distance value

    -   
        **Y**

        : Y distance value

    -   
        **Z**

        : Z distance value

• Label: User-provided name of the object (UTF-8)

• Disabled: List of disabled features

{{TitleProperty|Depth}}

• Clearance Height: The height needed to clear clamps and obstructions

• Final Depth: Final Depth of Tool- lowest value in Z

• Safe Height: The height above which Rapid motions are allowed. (Rapid safety height between locations)

• Start Depth: Starting depth of Tool - first cut depth in Z

{{TitleProperty|Drill}}

• Add Tip Length: Calculate the tip length and subtract from final depth

• Dwell Enabled: Enable dwell

• Dwell Time: The time to dwell between peck cycles

• Peck Depth: Incremental Drill depth before retracting to clear chips

• Peck Enabled: Enable pecking

• Retract Height: The height where feed starts and height during retract tool when path is finished

• Return Level: Controls how tool retracts Default=G98

{{TitleProperty|Path}}

• Active: Make False, to prevent operation from generating code

• Comment: An optional comment for this Operation

• User Label: User assigned label

• Tool Controller: Defines the Tool controller used in the Operation

{{TitleProperty|Rotation}}

(when available)

• Attempt Inverse Angle: Automatically attempt Inverse Angle if initial rotation is incorrect.

• Enable Rotation: Enable rotation to gain access to holes not normal to Z axis.

• Inverse Angle: Inverse the angle of the rotation. Example: change a rotation from -22.5 to 22.5 degrees.

• Reverse Direction: Reverse orientation of Operation by 180 degrees.
