Cutting force is a crucial factor in metalworking and machining processes. It determines the efficiency, tool life, and overall performance of cutting operations. Our Cutting Force Calculator helps you quickly and accurately calculate the force required for various machining operations like milling, turning, stamping, and punching. Whether you're working with steel, aluminum, or other metals, this tool simplifies the calculation process, ensuring precise and reliable results.

What is Cutting Force?

Cutting force is the force exerted by a cutting tool on a workpiece during a machining operation. It is essential to calculate this force to optimize tool performance, prevent tool wear, and improve machining efficiency. The cutting force depends on several factors, including material properties, feed rate, cutting speed, and depth of cut.

Cutting Force Formula

The cutting force can be calculated using different formulas based on the machining process:

Cutting Force Formula for Turning: Fc = Kc × ap × f

Where:

• Fc = Cutting force (N)
• Kc = Specific cutting force (N/mm²)
• ap = Depth of cut (mm)
• f = Feed rate (mm/rev)

Cutting Force Formula for Milling: Fc = Kc × ap × w

Where:

• Fc = Cutting force (N)
• Kc = Specific cutting force (N/mm²)
• ap = Depth of cut (mm)
• w = Width of cut (mm)

Cutting Force Formula for Stamping & Punching: F = S × t × L

Where:

• F = Cutting force (N)
• S = Shear strength of material (N/mm²)
• t = Thickness of material (mm)
• L = Perimeter of cut (mm)
