Anyways, in the video I talk about Mastercams Dynamic Mill and the two cutting scenarios that can occur which can lead to increased tool load...resulting in tool failure. 

First, a general overview of how Dynamic works so we can get a better understanding of how an why these cutting scenarios can come up. 

Second, we look at the types of shapes that result in these troublesome scenarios. 

Third, how can we better use Mastercam to avoid the situations from ever becoming an issue. 

As with everything in Mastercam, there is more than one way to deal with these. If you have a trick you'd like to add to this list, let me know! 


Here are the videos mentioned in the livestream..
