Enter the total distance (mm) and the laser speed (mm/min) into the Calculator. The calculator will evaluate the Laser Cutting Time. 

Laser Cutting Time Formula

LCT = D / FR


  • LCT is the Laser Cutting Time (minutes)
  • D is the total distance (mm)
  • FR is the laser speed (mm/min)

To calculate Laser Cutting Time, divide the total distance by the laser speed.

How to Calculate Laser Cutting Time?

The following steps outline how to calculate the Laser Cutting Time.

  1. First, determine the total distance (mm). 
  2. Next, determine the laser speed (mm/min). 
  3. Next, gather the formula from above = LCT = D / FR.
  4. Finally, calculate the Laser Cutting Time.
  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.

total distance (mm) = 40

laser speed (mm/min) = 23
