Description

This tool creates a pocketing operation from selected bottom faces, or walls, of one ore more pockets of the jobs base object.

The Path Pocket Shape object is made to be part of a Path Job.svg Path Job.

Usage

  1. Select the bottom or the wall(s) of a pocket. While it is usually easier to select the bottom, the walls have to be selected when a pocket goes through all.
  2. There are several ways to invoke the command:
    • Press the Path Pocket Shape.svg Path Pocket Shape button.
    • Select the Path → Path Pocket Shape.svg Pocket Shape option from the menu.
  3. Adjust the desired properties.

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.

  • DadosPlacement: Overall placement[position and rotation] of the object - with respect to the origin (or origin of parent object container)
    • DadosAngle: Angle in degrees applied to rotation of the object around Axis property value
    • DadosAxis: Axis(one or multiple) around which to rotate the object, set in sub-properties: x, y, z
      • DadosX: x axis value
      • DadosY: y axis value
      • DadosZ: z axis value
    • DadosPosition: Position of the object, set in sub-properties: x, y, z - with respect to the origin (or origin of parent object container)
      • DadosX: x distance value
      • DadosY: y distance value
      • DadosZ: z distance value
  • DadosLabel: User-provided name of the object (UTF-8)

Depth

  • DadosClearance Height: The height needed to clear clamps and obstructions
  • DadosFinal Depth: Final Depth of Tool- lowest value in Z
  • DadosFinish Depth: Maximum material removed on final pass. The height (thickness) of the last cutting level - set for a better finish.
  • DadosSafe Height: The height above which Rapid motions are allowed. (Rapid safety height between locations)
  • DadosStart Depth: Starting depth of Tool - first cut depth in Z
  • DadosStep Down: Incremental step down of Tool during operation

Extension

  • DadosExtension Corners: When enabled connected extension edges are combined to wires.
  • DadosExtension Length Default: Default length of extensions.

Face

  • DadosOffset Pattern: Clearing pattern to use. (Select in which manner the horizontal movements should be done.)

Path

  • DadosActive: make False, to prevent operation from generating code
  • DadosComment: An optional comment for this Operation
  • DadosUser Label: User assigned label
  • DadosTool Controller: Defines the Tool controller used in the Operation

Pocket

  • DadosCut Mode: Specifies a CW or CCW move for the cut
  • DadosExtra Offset: Extra offset to apply to the operation. Direction is operation dependent. (Extra value to stay away from final profile- good for roughing toolpath)
  • DadosKeep Tool Down: Attempts to avoid unnecessary retractions.
  • DadosMin Travel: Use 3D Sorting of Path (when multiple base geometries used).
  • DadosStart At: Start pocketing at center or boundary
  • DadosStep Over: Select the horizontal step over (Percent of tool diameter: 100% = tool diameter)
  • DadosUse Outline: Uses the outline of the base geometry.
  • DadosZig Zag Angle: Angle of the zigzag pattern. (Select the path angle relative to X axis.)

Rotation

  • DadosAttempt Inverse Angle: Automatically attempt Inverse Angle if initial rotation is incorrect.
  • DadosB_Axis Error Override: Visually orient B(y) rotations to model (error in FreeCAD rendering).
  • DadosEnable Rotation: Enable rotation to gain access to pockets or areas not normal to Z axis.
  • DadosInverse Angle: Inverse the angle of the rotation. Example: change a rotation from -22.5 to 22.5 degrees.
  • DadosReverse Direction: Reverse orientation of Operation by 180 degrees.

Start Point

  • DadosStart Point: The start point of this path
  • DadosUse Start Point: make True, if manually specifying a Start Point, then enter Start Points in the property data Start Points field

Tasks Window Editor Layout

Base Geometry

  • Add: adds selected element(s) which should be the base(s) for the path(s)
  • Delete: delete the selected item(s) in the Base Geometry list
  • Clear: clear all items in the Base Geometry list

Extensions

  • DadosShow All: If selected, all potential extensions are visualized. Enabled extensions in purple, disabled extensions in yellow.
  • DadosExtension Corners
  • DadosExtension Length Default
  • Enable
  • Disable
  • Clear

Depth

  • DadosStart Depth
  • DadosFinal Depth
  • DadosStep Down

Height

  • DadosSafe Height

Operation

  • DadosTool Controller
  • DadosCut Mode
  • DadosPattern (Offset Pattern)
  • DadosAngle (Zig Zag Angle)
  • DadosStep Over Percent (Step Over)
  • DadosPass Extension: The distance the facing operation will extend beyond the boundary shape (base geometry)
