Machinist Calc Pro – The CNC Machinist’s Calculator
Manufacturing tools, parts, and machines continue to advance rapidly. Machinist Calc Pro is designed as a practical addition to the toolkits of engineers, CNC programmers, and machinists.
Trigonometry Calculations
Right-triangle mathematics is essential in machining for calculating angles and part dimensions. Machinist Calc Pro can solve trigonometric equations and work with both U.S. customary and metric units.
Speeds and Feeds
Efficient machining depends on selecting appropriate feeds and speeds. Incorrect settings can waste production time or cause excessive tool breakage.
The calculator determines values including:
- Spindle speed in RPM
- Cutting speed
- Feed rate
- Chip load
Users enter the relevant material, cutting-tool, and machine information to perform these calculations.
Drill and Thread Size Tables
Built-in drill and thread-size tables reduce the need to search through separate reference charts or handbook pages.
Bolt-Pattern Layouts
For bolt-circle calculations, users can enter the starting angle, circle diameter, offsets, and number of bolts. The calculator then provides the required X and Y coordinates.
Practical Use
By combining common machining calculations and reference tables in one tool, Machinist Calc Pro can help programmers and machinists reduce lookup time while preparing CNC part programs.
