The image above represents co-efficient of friction. To calculate co-efficient of friction, two essential parameters are needed and these parameters are Frictional Resistance of the Tool acting on the Chip (F) and Force at the Tool Chip Interface acting Normal to the Cutting Force of the Tool (N).
The formula for calculating co-efficient of friction:
μ = F / N
Where:
μ = Co-efficient of Friction
F = Frictional Resistance of the Tool acting on the Chip
N = Force at the Tool Chip Interface acting Normal to the Cutting Force of the Tool
Let’s solve an example;
Find the co-efficient of friction when the frictional resistance of the tool acting on the chip is 48 and the force at the tool chip interface acting normal to the cutting force of the tool is 12.
This implies that;
F = Frictional Resistance of the Tool acting on the Chip = 48
N = Force at the Tool Chip Interface acting Normal to the Cutting Force of the Tool = 12
μ = F / N
That is, μ = 48 / 12
μ = 4
Therefore, the co-efficient of friction is 4.
Calculating the Frictional Resistance of the Tool acting on the Chip when the Co-efficient of Friction and the Force at the Tool Chip Interface acting Normal to the Cutting Force of the Tool are Given
F = μ x N
Where;
F = Frictional Resistance of the Tool acting on the Chip
μ = Co-efficient of Friction
N = Force at the Tool Chip Interface acting Normal to the Cutting Force of the Tool
Let’s solve an example;
Find the frictional resistance of the tool acting on the chip when the co-efficient of friction is 30 and the force at the tool chip interface acting normal to the cutting force of the tool is 15.
This implies that;

μ = Co-efficient of Friction = 30
N = Force at the Tool Chip Interface acting Normal to the Cutting Force of the Tool = 15
That is, F = μ x N
F = 30 x 15
F = 450
Therefore, the frictional resistance of the tool acting on the chip is 450 N.

Calculating the Force at the Tool Chip Interface acting Normal to the Cutting Force of the Tool when the Co-efficient of Friction and the Frictional Resistance of the Tool acting on the Chip is Given
N = F / μ
Where;
N = Force at the Tool Chip Interface acting Normal to the Cutting Force of the Tool
μ = Co-efficient of Friction
F = Frictional Resistance of the Tool acting on the Chip
Let’s solve an example;
Given that the co-efficient of friction is 20 and the frictional resistance of the tool acting on the chip is 180. Find the force at the tool chip interface acting normal to the cutting force of the tool?
This implies that;
μ = Co-efficient of Friction = 20
F = Frictional Resistance of the Tool acting on the Chip = 180
N = F / μ
That is, N = 180 / 20
N = 9
Therefore, the force at the tool chip interface acting normal to cutting force of the tool is 9 N.
