In FBM, How to stop the machining sequence if the tool path of the first operation is not generated?

Hello 

 

IF the first operation is created with problem (gouge). How to stop FBM to create the rest operations?

Hello Sean,

 

Thank you for your question.

FBM (Create Feature Process) will generate a complete process for your recognized feature, never a partial process. So, you will not get only a tapping operation without pre-drilling and spot drilling.

NX CAM detects collisions and gouges after the process is created, for multiple reasons. One of them is performance.

In your screenshot we see a complete process according to your own machining knowledge.

Obviously the spot drilling operation does not generate due to a gouge.

You should investigate why the tool gouges, and modify your machining knowledge to prevent this. There can be multiple reasons, like too large tool, wrong machining area etc.  I would be interested to know what's wrong in your example.

So FBM cannot abort the operations of that feature group if previous operations have problems?

If an operation has a gouge or collision, or no tool, or no geometry,or whatever fault, the subsequent operations are still generated. This is not specific feature based operation behaviour. It is true for all NX CAM operations: do what can be done and warn the user when collisions and gouges or other issues are detected on the way.

Perhaps an alternative means will help your workflow. There is a setting in the Customer Defaults that prevents a tool path from being post-processed if it has not been gouged checked or if the tool path has a gouge detected.

 

Go to Customer Defaults-->Manufacturing-->Output-->Postprocessing tab and turn on the Gouge Check before Postprocessing setting.

it is FBM not postprocessing, but still learned something

What's the root of the gouge? 

 

If it's FBM related, you should be able to solve it by strengthening your MKE rules.
