how to machine out corners of stock remaining

Hi, and thank you for taking the time in reading this message.

I am trying to cam out the attached file.  I can get the 2 bores milled out, and the outer profile, but it leaves corners of the stock remaining,  is there a way to knock this out in cam?  I do not know how to do it. I am new to Solidworks and the cam option.
