Path Drilling operation sample

Description

The Drilling command generates a drilling Operation in the Job.

How to use

  • Click the Drilling icon, or select the Drilling tool from the Path menu.
  • Choose a Tool controller from the pop-up selection dialogue window and confirm by pressing OK.
  • The holes available for processing with that Tool diameter will populate the list in the Base Geometry tab. 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.
  • Ensure the Depths, Final Depth is correct, and adjust if not.
  • Ensure the Heights, Safe and Clearance Heights are correct, and adjust if not.
  • In the Operation tab:
    • specify the Retract Height
    • enable and adjust the following as needed
      • Peck, and set the Peck Depth
      • Dwell, and set the Dwell time(period) in seconds
      • Use Tip Length
  • Click OK to generate the drilling path(s)

Usage 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.

Base

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

  • DataPlacement: Overall placement[position and rotation] of the object - with respect to the origin (or origin of parent object container)
    • DataAngle: Angle in degrees applied to rotation of the object around Axis property value
    • DataAxis: Axis(one or multiple) around which to rotate the object, set in sub-properties: x, y, z
      • DataX: x axis value
      • DataY: y axis value
      • DataZ: z axis value
    • DataPosition: Position of the object, set in sub-properties: x, y, z - with respect to the origin (or origin of parent object container)
      • DataX: x distance value
      • DataY: y distance value
      • DataZ: z distance value
  • DataLabel: User-provided name of the object (UTF-8)
  • DataDisabled: List of disabled features

Depth

  • DataClearance Height: The height needed to clear clamps and obstructions
  • DataFinal Depth: Final Depth of Tool- lowest value in Z
  • DataSafe Height: The height above which Rapid motions are allowed. (Rapid safety height between locations)
  • DataStart Depth: Starting depth of Tool - first cut depth in Z

Drill

  • DataAdd Tip Length: Calculate the tip length and subtract from final depth
  • DataDwell Enabled: Enable dwell
  • DataDwell Time: The time to dwell between peck cycles
  • DataPeck Depth: Incremental Drill depth before retracting to clear chips
  • DataPeck Enabled: Enable pecking
  • DataRetract Height: The height where feed starts and height during retract tool when path is finished
  • DataReturn Level: Controls how tool retracts Default=G98

Path

  • DataActive: make False, to prevent operation from generating code
  • DataComment: An optional comment for this Operation
  • DataUser Label: User assigned label
  • DataTool Controller: Defines the Tool controller used in the Operation

Rotation (when available)

  • DataAttempt Inverse Angle: Automatically attempt Inverse Angle if initial rotation is incorrect.
  • DataB_Axis Error Override: Visually orient B(y) rotations to model (error in FreeCAD rendering).
  • DataEnable Rotation: Enable rotation to gain access to holes not normal to Z axis.
  • DataInverse Angle: Inverse the angle of the rotation. Example: change a rotation from -22.5 to 22.5 degrees.
  • DataReverse Direction: Reverse orientation of Operation by 180 degrees.
