CNC Tools

CNC Tools is a machining calculator and learning app for CNC operators, machinists, manufacturing students, workshop trainees and anyone working with milling, turning, drilling or metal-cutting calculations.

Use the app to perform CNC calculations quickly, review machining relationships and improve your understanding of speeds, feeds, cutting conditions and production planning. The card-based interface makes it easy to open a tool, enter values and view results without repeating every formula manually.

CNC MACHINING CALCULATORS

The app includes a growing collection of tools for everyday machining and workshop calculations. Available tools may cover:

• Spindle speed and RPM

• Feed rate and cutting feed

• Cutting speed conversion

• Depth of cut

• Chip load and feed per tooth

• Material removal rate

• Surface finish estimation

• Horsepower and power requirements

• Torque calculations

• Turning speed and feed

• Lathe thread cutting

• Taper turning

• Boring bar deflection

• Parting-off speed

• End-mill selection

These tools can support classroom exercises, workshop preparation and setup planning.

MORE TOOLS THROUGH IN-APP PURCHASE

Additional calculators may be unlocked through a one-time in-app purchase. The expanded collection may include slot milling, face milling, drilling speed and feed, peck drilling, bolt-circle coordinates, hole-pattern generation, arc radius and centre calculations, chamfer dimensions and fillet calculations.

Further tools may support material-weight estimation, CNC job-cost estimation, cycle-time analysis, machine utilisation, overall equipment effectiveness, tolerance limits, fits and clearances, and measurement uncertainty. These calculators connect machining parameters with production planning, costing and quality control.

FREE TO DOWNLOAD

CNC Tools can be downloaded and used for free. Selected calculators are available without payment, allowing you to explore the app and perform CNC calculations.

UNLOCK ADDITIONAL CALCULATORS

A one-time in-app purchase unlocks more tools inside the same app. Locked calculators are clearly marked so you can decide whether the expanded collection is useful for your work or study.

WHY USE CNC TOOLS?

• Quick access to common machining calculations

• Useful for CNC milling, turning and drilling

• Suitable for workshops and classrooms

• Clear inputs and easy-to-read results

• Reduces repeated manual formula work

• Selected calculators available free

• Additional specialised tools available by in-app purchase

• Simple navigation and mobile design

LEARN WHILE YOU CALCULATE

The app reinforces the relationships between spindle speed, cutting speed, feed, chip load, depth of cut, tool life, power and machining time. It can serve as a portable reference while studying, training or preparing a machining operation.

Always select values that suit the workpiece material, cutting tool, machine capacity, workholding method and manufacturer recommendations. Actual machining conditions vary, so calculated results should be treated as starting points rather than guaranteed production settings.

IMPROVE YOUR CNC WORKFLOW

Whether you are checking RPM, estimating feed rate, comparing cutting conditions or preparing a machining job, CNC Tools keeps important calculations together in one place. Use the free tools for common tasks and unlock the additional collection when you need broader machining, cost and quality calculations.

Useful for machinists, CNC programmers, setup technicians, engineering students, manufacturing trainees, production teams, teachers and hobbyists.

DISCLAIMER

CNC Tools is an independent educational and general-reference app. It is not affiliated with any machine-tool manufacturer, cutting-tool company, institute or certification authority. Verify critical results with machine manuals, tooling data, engineering standards and professional judgement. Follow workshop safety rules and never exceed the rated limits of your machine, tool, holder or setup.
