IMPORTANT: All examples are based on the default U.S. units
mode, displaying entries and calculations in U.S. units. Also note
that if an attempt is made to nd a solution (using the Machinist
functions) without having stored the minimum required values, the
calculation will not be performed. Instead, the currently stored value
for the selected function will be displayed. See Key Denitions
section for function requirements .
cuTTINg SPEED
Cutting Speed is the speed of the workpiece surface relative
to the edge of the cutting tool during a cut, typically measured
in surface feet per minute. You can calculate Cutting Speed by
entering the Diameter of the tool or material you’re using and
the RPM (Spindle Speed).
