Machinist Function Keys
C
Cutting Speed — Enters or calculates Cutting
Speed. Unitless entries assumed meters per minute
in Metric mode; feet per minute in U.S. mode.
Calculates Cutting Speed given entered Diameter
and RPM (Spindle Speed). Result is displayed as a
whole number.
gC
Radial Chip Thinning (RCT) — Enters a Cut Depth
and calculates a Radial Chip Thinning factor to
increase the Feed Rate given Feed Per Tooth, Tool
Diameter and a Cut Depth that is less than one-
half the Tool Diameter. Unitless entries assumed
millimeters in Metric mode; Inches in U.S. mode.
R
Revolutions per Minute — Enters or calculates
RPM (Spindle Speed). Calculates RPM given entered
Diameter and Cutting Speed. Result is displayed as a
whole number.
gR
3-Wire Measurement (3-W Measure) — Enters
or calculates a Three-Wire Measurement. Unitless
entries assumed millimeters in Metric mode;
Inches in U.S. mode. Calculates the minimum and
maximum Three-Wire Measurements and Pitch
Diameters given entered Thread Size and Wire Size,
assuming an External thread type. If a Three-Wire
Measurement value is entered, the Pitch Diameter
calculation is based on this entered measurement.
