Calculate laser cutting time from cut length and cutting speed, then add pierces, travel and setup for a whole job, parts per hour and machine cost.
Laser Cutting Time Formula
Variables:
- LCT is the Laser Cutting Time (minutes)
- D is the total distance (mm)
- FR is the laser speed (mm/min)
For active cutting time, divide path length by average cutting speed using matching units. The job-time mode adds per-part piercing, rapid travel and other cycle time, multiplies by quantity, and adds setup once. Capacity excludes setup; optional machine-time cost includes all entered job time and assumes the displayed dollar rate.
How to Calculate Laser Cutting Time?
The following steps outline how to calculate the Laser Cutting Time.
- First, determine the total distance (mm).
- Next, determine the laser speed (mm/min).
- Next, gather the formula from above = LCT = D / FR.
- Finally, calculate the Laser Cutting Time.
- For the example, choose Total job time and capacity with one part and leave extras blank, or use an active-cutting reverse mode. Then select Calculate.
Example Problem :
Use the following variables as an example problem to test your knowledge.
total distance (mm) = 40
laser speed (mm/min) = 23
FAQ Section
What factors can affect laser cutting time?
The laser cutting time can be influenced by several factors including the material type, thickness, laser power, and the complexity of the cut. Different materials and thicknesses require adjustments in laser speed and power, which can increase or decrease the cutting time.
How can I improve the efficiency of my laser cutting process?
Improving efficiency can be achieved by optimizing the laser settings such as power, speed, and frequency based on the material being cut. Additionally, using assist gases appropriate for the material, maintaining a clean and focused laser, and minimizing the complexity of the cut paths can also enhance efficiency.
What safety precautions should be taken during laser cutting?
Safety precautions include wearing protective eyewear suitable for the laser’s wavelength, ensuring proper ventilation to remove harmful fumes and particles, keeping flammable materials away from the cutting area, and using the laser equipment according to the manufacturer’s instructions.
Can laser cutting be used on all types of materials?
While laser cutting is versatile, it is not suitable for all materials. Suitability depends on the specific laser, material and process. Only use materials approved by the equipment manufacturer and its safety guidance; hazardous materials such as PVC must not be processed on equipment that is not approved for them. This time estimator does not assess material safety or cutting feasibility.
