A machinist calculator is a hand-held
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
Modern Machinist Speed and Feed Calculators
Because early Machinist Calculators were limited by the analog user interface and computing power, Speeds and Feeds were fairly rudimentary, most of the time providing speed and feed independently from each other.
Some of the modern Machinist Calculators have departed from the scattered approach to Speeds and Feeds and incorporated selectors for all supported tool types, materials, and tool data input fields on to a single screen, making Speeds and Feeds calculator a first-class citizen. For example, FSWizard[2] - the first app in its class, contains cutting data for hundreds of work-piece materials and dozens of tool types and allows to calculate Speeds and Feeds with high accuracy and reliability. As a bonus, it contains other useful references to Drill Charts, Geometry Calculators, and so on.
Steps required to accurately calculate Speeds and Feeds include:
- Selecting Work-Piece Material
- Selecting Tool Type, Tool Material and Coating
- Entering Tool Diameter, Tool Stick-out, and Flute Length
- Entering Engagement values, Depth and Width of Cut
With modern GUI these steps take only a few seconds and yield results far greater than having to go through typical trial and error cycle.
