After you run CAM Assist, Machinability feedback in the Program stage can show these issues for surfaces it couldn't machine with your tools. Each one names a tool and a change that would make the surface machinable. It's safe to continue: CAM Assist just doesn't machine those surfaces.
Insufficient tool stick-out
Insufficient usable tool length
Tool over-engagement
What they mean
| Issue | Meaning | Recommended change |
|---|---|---|
| Insufficient tool stick-out | The holder would hit the part. | Increase the named tool's stick-out by the amount shown. |
| Insufficient usable tool length | The tool's shank would rub the part. | Increase the named tool's usable length, or reduce its shank diameter. |
| Tool over-engagement | No tool is small enough to machine the surface without over-engaging. CAM Assist won't machine a corner with a tool of the same diameter. | Add a tool with the diameter and usable length shown. |
Is it safe to continue?
Yes. CAM Assist leaves those surfaces unmachined. Machine them yourself in your CAM package, or make the change and run CAM Assist again.
Only change a tool's stick-out or usable length if you can set the tool up that way on the machine.
How to clear it
- In the Program stage, click Machinability feedback, then click the issue.
- Click a recommendation to highlight the surfaces it affects.
- For stick-out or usable length, click Edit tool next to the recommendation and change Stickout or Usable length (LU). See Edit a tool's geometry. For over-engagement, add a suitable tool to your tool library. See Add a tool assembly.
- Click Run CAM Assist again.
Edit tool is unavailable when:
- "Tool was not found in any of the currently selected libraries." The tool isn't in a library you selected for this part.
- "Built in tools cannot be edited. Try another tool library" The tool is in a CloudNC library. Copy it to your own library first. See Copy tools to another library.
Still seeing it?
If you've made the change and still see this warning, contact CloudNC support. Include the part file, your tool library and your CAM Assist log files: see Find your CAM Assist log files.
