A Machinist Calculator is a hand-held calculator programmed with built-in formulas making it easy and quick for machinists to establish speeds, feeds and time without guesswork or conversion charts. Formulas may include revolutions per minute (RPM), surface feet per minute (SFM), inches per minute (IPM), feed per tooth (FPT). A cut time (CT) function takes the user through a calculation step-by-step. Other features may include a metric-English conversion function, a stop_watch/timer function and a standard math calculator.
This type of calculator is useful for machinists, programmers, inspectors, estimators, supervisors, and students.
