The values change slightly according to the state of a machine to be used and method of workholding. Adjust the values depending on an actual machine condition, referring to the above values. (Note 2) For end mills with a carbide shank, you will be able to set about 20 percent higher cutting conditions. (Note 3) Please note the following when machining hardened steel with MP8010. Please shorten the overhang length as much as possible. Use with carbide shank recommended. Please note the setting of the depth of cut especially to prevent the fracture. CUTTING SPEED FORMULAE 1.
