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.gC radial chip Thinning (rcT) — Enters a CutDepth and calculates a Radial Chip Thinningfactor to increase the Feed Rate given Feed PerTooth, Tool Diameter and a Cut Depth that is lessthan one-half the Tool Diameter. Unitless entriesassumed Inches in U.S. mode; millimeters inMetric mode.R revolutions per Minute — Enters or calculatesRPM (Spindle Speed). Calculates RPM givenentered Diameter and Cutting Speed. Result isdisplayed as a whole number.gR 3-Wire Measurement (3-W Measure) — Entersor calculates a Three-Wire Measurement. Unitlessentries assumed Inches in U.S. mode; millimetersin Metric mode. Calculates the minimum andmaximum Three-Wire Measurements and PitchDiameters given entered Thread Size and WireSize, assuming an External thread type. If aThree-Wire Measurement value is entered, thePitch Diameter calculation is based on this enteredmeasurement. (cont’d)
