Cutting Force Calculator
Calculate the required cutting force for your machining operations with precision. Our tool helps optimize your machining parameters for better efficiency and tool life.
Main Cutting Force (Fc)
The tangential force acting on the cutting tool.
Feed Force (Ff)
The force in the feed direction.
Radial Force (Fr)
The force perpendicular to the cutting direction.
Power Requirement
Estimated power needed for the operation.

Cutting Force Formula
The main cutting force (Fc) is calculated using:
Fc = kc × ap × f × (sin κr)^n
Where:
- kc = specific cutting force (N/mm²)
- ap = depth of cut (mm)
- f = feed rate (mm/rev)
- κr = tool approach angle
- n = correction factor (typically 0.75-0.85)
Frequently Asked Questions
What is cutting force in machining?
Cutting force is the resistance exerted by the workpiece material against the cutting tool during machining. It’s a critical parameter that affects tool wear, power consumption, and machining accuracy.
How does material type affect cutting force?
Harder materials generally require higher cutting forces due to their increased resistance to deformation. Our calculator accounts for material-specific coefficients to provide accurate results.
Why is cutting force important?
Understanding cutting forces helps in:
- Selecting appropriate machine tools
- Determining power requirements
- Predicting tool life
- Minimizing workpiece deformation
- Optimizing machining parameters
