Cutting Force is the force in the direction of cutting, the same direction as the cutting speed. It represents the resistance encountered by the cutting tool during material removal processes.
The calculator uses the formula:
Where:
Explanation: The specific cutting energy represents the energy required to remove a unit volume of material, and when multiplied by the cross-sectional area of the uncut chip, it gives the total cutting force.
Details: Accurate cutting force calculation is crucial for tool selection, machine tool design, power requirement estimation, and optimizing machining parameters for efficient material removal processes.
Tips: Enter specific cutting energy in J/m³ and cross-sectional area of uncut chip in m². Both values must be positive numbers for accurate calculation.
Q1: What factors affect specific cutting energy?
A: Material properties, cutting speed, feed rate, tool geometry, and cutting conditions all influence specific cutting energy values.
Q2: How is cross-sectional area of uncut chip determined?
A: It is calculated as the product of depth of cut and feed per revolution in turning operations, or appropriate dimensions in other machining processes.
Q3: What are typical cutting force values?
A: Cutting forces vary widely depending on material and machining conditions, ranging from a few Newtons for soft materials to thousands of Newtons for hard materials.
Q4: How does cutting force affect tool life?
A: Higher cutting forces generally lead to increased tool wear and reduced tool life, making force minimization an important consideration in machining optimization.
Q5: Can this formula be used for all machining operations?
A: While the fundamental relationship holds, specific modifications may be needed for different machining operations like milling, drilling, or grinding.
