Proper machining depth and width of cut are just as important as proper Speeds and Feeds.
This is not only importanttant for professional machinists, who are machining on the edge of their tooling and setup capability, but also for hobbyists, who often face limits from the machine rigidity side of the equation.
HSMAdvisor Speed and Feed calculator has a unique tool used for figuring the best engagement values for each particular cut you are making.
It is called Performance Slider. And it adjusts expected load on the tool and machine depending on your preferred machining mode.
Check out this video I made that explains Performance Slider' functionality:
