How to Calculate and Solve for Cutting Ratio / Mechanics of Chips Formation

This image above represents cutting ratio. To calculate cutting ratio, two essential parameters are needed and these parameters are Uncut Chip Thickness (t) and Chip Thickness after Cut (tc).

The formula for calculating cutting ratio:

r = t / tc

Where:

r = Cutting Ratio
t = Uncut Chip Thickness
tc = Chip Thickness after Cut

Let’s solve an example;
Find the cutting ratio when the uncut chip thickness is 20 and the chip thickness after cut is 2.

This implies that;

t = Uncut Chip Thickness = 20
tc = Chip Thickness after Cut = 2

That is, r = t / tc
r = 20 / 2
r = 10

Therefore, the cutting ratio is 10.

Calculating for Uncut Chip Thickness when the Cutting Ratio and the Chip Thickness after Cut is Given

t = r x tc

Where;

t = Uncut Chip Thickness
r = Cutting Ratio
tc = Chip Thickness

Let’s solve an example;
Find the Uncut chip thickness when the cutting ratio is 10 and the chip thickness is 5

This implies that;

r = Cutting Ratio = 10
tc = Chip Thickness = 5

t = r x tc
So, t = 10 x 5
t = 50

Therefore, the uncut chip thickness is 50.

Calculating for Chip Thickness when the Cutting Ratio and Uncut Chip Thickness are Given

tc = t / r

Where;

tc = Chip Thickness
r = Cutting Ratio
t = Uncut Chip Thickness

Let’s solve an example;
Find the chip thickness when the cutting ratio is 20 and the uncut chip thickness is 40.

This implies that;

r = Cutting Ratio = 20
t = Uncut Chip Thickness = 40

tc = t / r
So, tc = 40 / 20
tc = 2

Therefore, the chip thickness is 2.
