Enter the chip thickness before cutting and the chip thickness after cutting into the Chip Thickness Ratio Calculator. The calculator will evaluate the Chip Thickness Ratio. 

Chip Thickness Ratio Formula

The following two example problems outline the steps and information needed to calculate the Chip Thickness Ratio.

CTHR = T1/T2


  • CTHR is the Chip Thickness Ratio ( )
  • T1 is the chip thickness before cutting 
  • T2 is the chip thickness after cutting 

How to Calculate Chip Thickness Ratio?

The following steps outline how to calculate the Chip Thickness Ratio.

  1. First, determine the chip thickness before cutting. 
  2. Next, determine the chip thickness after cutting. 
  3. Next, gather the formula from above = CTHR = T1/T2.
  4. Finally, calculate the Chip Thickness Ratio.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

chip thickness before cutting = 3

chip thickness after cutting = 2

CTHR = T1/T2 = ?
