Question:

In grinding, both the wheel and workpiece are moving (or rotating). Using the data in Figure 27-11 and assuming that you are doing surface grinding (see Figure 27-1), what are some typical MRR values? How do these compare to MRR values for other machining processes, such as milling? What is the significance of this?
