Chamfering

wayne_sauder

Can anyone explain the setting in the chamfer tool path? I have played around with many of them, but I always get collision warnings in simulation. 
How do you set it to chamfer an edge that ends against an island without crashing the island?

@wayne_sauder Even without the island the simulation will see a collision because the tool is technically cutting into the part since the model doesn't have a chamfer feature on it. In the future, we may add an option to avoid chamfer or deburring operations in simulation as collisions. 


To avoid obstacles one method is to turn on the collision detection feature. This option will allow you to pick certain faces to avoid. Take a look at this example. 




I set the chamfer width to .02in and the axial shift to .1in




Go to collisions and create a collision group, Set to "trim and re-link" Turn on "Check additional bodies" and set the stock and surface tolerance factor to .05.   (This may vary depending on the application and the desired clearance)






Under "Additional Check Bodies" select the faces you want to avoid. Do not select the entire part since the chamfer tool is technically cutting into the part. We only want to avoid these faces. 





Click ok and generate the toolpath. This should avoid the check faces. In the future we will also have an automatic deburring operation that will help automate this process. Hope this helps! If you still need help please message me and I can share you into the example.

 Thanks, that helps a lot. 

 I've become used to fusion and its quirks; it doesn't give collision warnings if I use Chamfer for a deburring operation. 

 I'm looking forward to an automatic deburr operation being added.
