Tests & results

Experiment 1: plywood (5 mm)

In order to test the material, we will apply the built-in material test in the Lightburn software which can be accessed as shown in (1). The material test has many parameters that can adjusted to obtain the best result, our test parameters as set as shown in (2). The test scale that will be engraved is shown in (3).

• After setting-up everything, we start engraving by clicking on Start button shown in (2). The result of the material test is shown in (4). From the result obtained, we can say that at a speed of 100 mm/min with a laser power in a range of  (74 ~100 %) we can cut through the wood. Check the video below.

• After applying the material test, we started doing small projects, such as: medal key contains our supervisor’s name as shown in (5), and a photo for one of our team members as shown in (6). Check the video below.

• Here is another engraving test of a photo, the copyrights of the photo goes to the dean of college of engineering, Dr. Adel Aldelbhi. The result is shown in (7). Check the video below.

• Here is another engraving test of a photo, the copyrights of the photo goes to the supervisor Dr. Hesham Enshasy. The result is shown in (8). Check the video below.

• After applying different experiments with different thicknesses, we are able to prepare the following table below that demonstrates the engraving parameters settings for wood. According to the table, in order to cut a plywood of 5mm thickness, we need to adjust the parameters to be 600 mm/min for the speed, 100% of the laser power, and 5 passes.
