Specific cutting force
For power, torque and cutting force calculations, the specific cutting force, or k c1, is used.It can be explained as the force, F c, in the cutting direction (see picture), needed to cut a chip area of 1 mm that has a thickness of 1 mm.The k c1 value is different for the six material groups, and also varies within each group.. The k c1 value is valid for a neutral insert with …

Tensile Strength to Load Capacity Calculator
To calculate tensile load from tensile strength, you would need to know the cross-sectional area of the material being subjected to the load. You can use the formula: Tensile Load (in pounds or newtons) = Tensile Strength (in pounds per square inch or pascals) × Cross-Sectional Area (in square inches or square meters).
