U ser 's GUide — 9gS Preference Settings (Prefs) — Accesses variouscustomizable settings, such as dimensional answerformats (see Preference Settings section).Machinist function KeysC Cutting Speed — Enters or calculates CuttingSpeed. Unitless entries assumed feet per minutein U.S. mode; meters per minute in Metric mode.Calculates Cutting Speed given entered Diameterand RPM (Spindle Speed). Result is displayed as awhole number.R Revolutions per Minute — Enters or calculatesRPM (Spindle Speed). Calculates RPM given enteredDiameter and Cutting Speed. Result is displayed as awhole number.gRModel 4087only3-Wire Measurement (3-W Measure) — Entersor calculates a Three-Wire Measurement. Unitlessentries assumed Inches in U.S. mode; millimeters inMetric mode. Calculates the maximum Three-WireMeasurement and Pitch Diameter given enteredThread Size and Wire Size, as long as the selectedThread Classification is set to an External threadtype. If a Three-Wire Measurement value is entered,the Pitch Diameter calculation is based on thisentered measurement.f Feed Rate — Enters or calculates Feed Rate.Unitless entries assumed inches per minute inU.S. mode; millimeters per minute in Metric mode.Calculates Feed Rate given values for Cutting Feedand RPM (Spindle Speed) or Feed per Tooth (ChipLoad), RPM and Number of Teeth. If all of thesevalues are entered, the calculation based on CuttingFeed and RPM takes precedence.(cont'd)
