C
cutting Speed — Enters or calculates Cutting
Speed. Unitless entries assumed meters per minute

Enters or calculates
RPM (Spindle Speed). Calculates RPM given entered
Diameter and Cutting Speed. Result is displayed as a

or calculates a Three-Wire Measurement. Unitless
entries assumed millimeters in Metric mode;
Inches in U.S. mode. Calculates the minimum and
