3D Experience Machining vs hyperMILL

Hi

We're having a demo for a customer that currently is using hyperMILL for NC simulation and programming. The customer is using the 3D Experinece platform for process planning (PPL) already and would like to know if there is any value in also swithching to 3D Exp machining. The already understand the value of single source, so what other value might there be? how much time would the customer save by going into 3D Exp Machining?
