When a feature cannot be machined with any of the tools available in the selected Cut Config, Toolpath will show the feature in red and highlight machinability issues on the right hand side of the Overview page.
Unmachinable features occur when Toolpath is unable to match any of the available tools to the part geometry. This happens when:
- No tool with the correct geometry for the feature is available (i.e. no tool with a long enough length below holder or small enough diameter is eligible).
- A tool is geometrically valid, but is ineligible because it does not have a preset mapped to the cutting role, or type of operation, required for the feature.
Tool Inspection can help identify why a particular tool was not used on a particular feature. To access Tool Inspection:
- Enter the feature details for the unmachinable feature. This can be done by clicking on the feature name from any Toolpath report page on the right hand side, or by using the mouseover selection option and clicking on the feature.
- On the feature details page, you can view Tool Inspection for both roughing and finishing.
- For Roughing, click on the magnifying glass icon next to Roughing Tool. For Finishing, click on the arrow icon next to Finishing Tool.
The finishing tool can be swapped using the instructions here.
- For Roughing, click on the magnifying glass icon next to Roughing Tool. For Finishing, click on the arrow icon next to Finishing Tool.
- This will open Tool Inspection. Compatible tools will show as "Compatible" in the second column, and incompatible tools will show the reasoning in the second column:
- Hover over the incompatibility message for more details on a specific tools geometry:
- If a tool does not have the appropriate preset applied in the cutting role necessary to machine the feature, Toolpath will indicate the tool is compatible but the preset role is missing in the Cut Config:
To resolve this issue, a preset on the geometrically eligible tool needs to be applied to the cutting role being used for the feature in the Cut Config. Please see How to Create Cut Configs and Managing and Applying Tool Presets for more information on mapping presets to cutting roles.
