Description
Cet outil utilise un algorithme adaptatif pour créer des chemins de compensation et de profilage qui gèrent l'engagement des outils de coupe de manière à ce que l'engagement et l'enlèvement de matière ne dépassent jamais une valeur maximale.
Utilisation
Les instructions d'utilisation pour l'opération Adaptive sont présentés ici.
Opération de base
- Press the File:Path-Adaptive.svg Adaptive icon, or select the Adaptive tool from the Path menu.
- Select the tool controller for the Operation from the Tool controller dialogue pop up window, if prompted.
- Adjust the operation depths as needed in the Depths tab: Start Depth, Finish Depth, Step Down.
- Make adjustments in Heights tab if needed.
- Configure settings in the Operations tab:
- (See the Properties -> Adaptive section below.)
- Set the Step Over value as a percentage of the diameter of the Tool.
- If you wish to preview the result before accepting the settings, click Apply
- Click OK button to confirm and generate paths.
Preliminary Notes About Adaptive Clearing
- Depending on the size and complexity of the area for the operation, is might be better to not recompute the operation after every property change; rather, consider:
- The File:Path-Adaptive.svg Adaptive operation might contain a few bugs yet to be clearly identified. Please report bugs and issues in the FreeCAD Path/CAM Forum.
- All tool shapes may not be respected with this operation. Check the FreeCAD forum for further details.
- Should you choose to run the path simulator in the Path Workbench, it only uses the standard end mill to simulate paths. Therefore, you will not see tool-shape-specific material removal. Material removal is shown using the end mill shape.
Properties
Note : The names of some Properties in this list differ a little from the same settings used in the Task Window Editor.
Adaptive
- DonnéesForce Inside-Out: Force plunging into material inside and clearing towards the edges
- DonnéesHelix Angle: Helix ramp entry angle (degrees)
- DonnéesHelix Diameter Limit: Limit helix entry diameter, if limit larger than tool diameter or 0, tool diameter is used
- DonnéesKeep Tool Down Ratio: Max length of keep tool down path compared to direct distance between points
- DonnéesLift Distance: Lift distance for rapid moves
- DonnéesOperation Type: Type of adaptive operation: Clearing or Profiling
- DonnéesSide: Side of selected faces that tool should cut: Inside or Outside
- DonnéesStep Over: Percent of cutter diameter to step over on each pass
- DonnéesStock to Leave: How much stock to leave (i.e. for a separate finishing operation)
- DonnéesTolerance: Influences accuracy and performance
- DonnéesUse Helix Arcs: Use Arcs (G2) for helix ramp
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.
- DonnéesPlacement: Overall placement[position and rotation] of the object - with respect to the origin (or origin of parent object container)
- DonnéesAngle: Angle in degrees applied to rotation of the object around Axis property value
- DonnéesAxis: Axis(one or multiple) around which to rotate the object, set in sub-properties: x, y, z
- DonnéesX: x axis value
- DonnéesY: y axis value
- DonnéesZ: z axis value
- DonnéesPosition: Position of the object, set in sub-properties: x, y, z - with respect to the origin (or origin of parent object container)
- DonnéesX: x distance value
- DonnéesY: y distance value
- DonnéesZ: z distance value
- DonnéesLabel: User-provided name of the object (UTF-8)
Depth
- DonnéesClearance Height: The height needed to clear clamps and obstructions
- DonnéesFinal Depth: Final Depth of Tool- lowest value in Z
- DonnéesFinish Depth: Maximum material removed on final pass.
- DonnéesSafe Height: The above which Rapid motions are allowed.
- DonnéesStart Depth: Starting Depth of Tool- first cut depth in Z
- DonnéesStep Down: Incremental Step Down of Tool
Path
- DonnéesActive: make False, to prevent operation from generating code
- DonnéesComment: An optional comment for this Operation
- DonnéesTool Controller: Defines the Tool controller used in the Operation
- DonnéesUser Label: User assigned label
