Machinist calculator (original) (raw)
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, step-by-step, through a calculation to determine cycle time (execution time) for a given tool motion. Other features may include a metric-English conversion function, a stop watch/timer function and a standard math calculator.

| dbo:abstract | 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, step-by-step, through a calculation to determine cycle time (execution time) for a given tool motion. 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. When Handheld Machinist calculators first came to market they were complicated to use due to their small liquid-crystal displays and were fairly expensive with a price of around 70−70-70−80. These older units were missing many features and could not be upgraded. With the invention of the smartphone, Machinist Calculators now have many more features and are ever evolving with constant software upgrades. One popular example of a Machinist calculator is an application called "CNC Machinist Calculator Pro". This machinist calculator has 35 subsections of machining calculations which include turning, milling (machining), drilling, tapping, Grinding (abrasive cutting), gun drilling, GD&T, M-codes, G-codes, thread data, Threading (manufacturing), Position tolerance, bolt circle, surface finish, over wire thread pitch dimensions, center drill dimensions, triangle solver, machinability data with Surface feet per minute (SFM) and RPM conversions, List of materials properties, Brinell scale material hardenability, hardness conversions, scientific calculator functions, etc..
