3. Computer controlled cutting¶

For the group assignment, thoroughly analyze and describe the focus, power, speed, rate, kerf, joint clearance, and various types of your lasercutter. Document your observations on the group’s collaborative platform and share personal reflections on your individual page regarding newfound insights. As for individual tasks, devise, lasercut, and document a versatile construction kit that adjusts for the lasercutter’s kerf, enabling diverse assembly options. Additionally, utilize the vinyl cutter to execute a project.

Shuriken¶

First, we make the circles with their radii as shown in the images.
With the ARC tool, we click on our largest circle. The second click is on the second circle, where we set an angle of 51°.
We repeat the same step, but our reference is the third circle, with an angle of 89°.
We select our two shapes created with the ARRAY tool, using the center of our first circle as a guide, and indicate to make 4 copies.
With the same ARC tool, we select the two points as seen in the image and almost completely close the circumference.
We delete the excess from the circle we previously made.
We select and, using the ARRAY tool, make 4 copies.
Using the LINE tool, from the center of our first circle, we create a line at an angle of 73°.
From the guideline we created with the OFFSET tool, we set a distance of 1.025 on both sides.
With the ARRAY tool, we make four copies.
We create a guideline using the LINE tool, and with the OFFSET tool, we set a distance of 1.025 on both sides.
Starting from the beginning with a distance of 5, we create a horizontal line.
We select and create four copies using the ARRAY tool.
We click on the reference circles, excluding the first one, and delete them.
There you go, our Shuriken design is now complete.
We copy our design, this time 9 times.
We proceed to save our file in DXF format.

Logo and Labels¶

We start by making a circle with a radius of 20.297.
We draw a second circle with a smaller radius of 18.797.
Now a final circle with a radius of 14.647.
Now, using the LINE tool from the midpoint of our circumference, we draw a line at an angle of 114°.
With the line created using the OFFSET tool, we create 2 lines with a distance of 2.
Using the MIRROR tool with a midpoint at a 90° angle.
Now we perform an OFFSET of 5 units of distance.
Then another OFFSET with a distance of 4.
We create a 90° angle using the MIRROR tool.
Using the TRIM tool, we delete all overlapping lines.
With the LINE tool, we draw a line with a distance of 11.5.
Another line with a distance of 1.5 at a 90° angle.
Draw a horizontal line with a length of 3.35.
Draw another vertical line with a length of 18.75.
Use the CIRCLE tool and select the two-point option to create a circle with a diameter of 6.22.
Draw a vertical line upwards with a length of 3.75.
Use the ARC tool with a radius of 4.75.
Draw a horizontal line with a length of 8.
Use the MIRROR tool to complete the other half of the letter, and finally, delete the extra lines.
Use the FILLET tool to round all the corners with a radius of 0.5.
Use the OFFSET tool on our letter with a distance of 0.6, then use the TRIM tool to remove overlapping lines.
Save our finished file in DXF format.
