Computer Controlled Cutting
brief Insight of this week
This week, our main task was Computer Controlled Cutting, which included both group and individual tasks. The objective of this assignment was to properly document our work and use machines to print designs. We were required to print parametric designs using the laser cutter and vector designs using the vinyl cutter. Our goal was not only to use these machines correctly but also to document the entire process properly so that this technology can be effectively and accurately used in the future. During this, we also learned how to create a precise balance between design and printing, and we gained knowledge about machine setup, operation, and safety standards.
About Computer Controlled Cutting
Overview: - Computer Controlled Cutting refers to using a computer to operate cutting tools or machines. These machines can cut, shape, or carve materials like metal, wood, plastic, or fabric based on digital designs or instructions. It works by sending commands from a computer to a machine like a CNC (Computer Numerical Control) cutter or laser cutter. The machine then follows the computer’s instructions to make precise cuts with high accuracy, reducing human error. This technology is widely used in manufacturing, engineering, and design.
Group Assignment
Throughout this week, our focus was on laser cutting and scanning technologies. We worked as a team and made an effort to deeply understand both of these techniques. The objective of this task was not only to use these machines correctly but also to comprehend their working principles, setup, and operation. The main objectives of this task were as follows:
Individual Assignment
Exploring Parametric Design Features in Solid work and Fusion 360
Parametric Design in Solid work : -

STEP 1: First, a circle was created, and its dimensions were set through "Smart Dimension" option |
STEP 2: By clicking on the 'Linear Sketch Pattern' option, the second option was selected. Then, the number for the 4 outer parts was entered, and upon pressing Enter, the 4 outer parts were automatically generated. |

![]() |
STEP 3: Next, by clicking on the 'Extruded Boss/Base' option and pressing Enter, the shape of the design was created. |
STEP 4: Afterward, I created another circle at the center to form a hole and set its dimensions. Then, I selected the "Through All" option and confirmed, resulting in a visible hole at the center with openings on both sides. |
![]() |
STEP 5: After this, my final parametric design was successfully created and ready. |
Design Assembling in Solid work
![]() |
![]() |
First, I opened the initial parametric design in the assembly part. Then, I copied the same design four times and began the assembly process. |
Afterward, I press-fit each design one by one, completing the entire assembly. |
Parametric Design in Fusion 360
![]() |
![]() |
STEP 1: Make a rectangle with dimensions 150 mm by 120 mm. |
STEP 2: A rectangle was made for the press feet with a width of 3 mm and a height of 10 mm, then trimmed to form four corners. |
![]() |
![]() |
STEP 3: A 200 mm rectangle was created, and a round shape was applied to the top. |
STEP 4: Then, a rectangle was created again for the press fit with a width of 3 mm and a height of 10 mm. |

STEP 5: The first design was extruded using the Boss-Extrude feature. |
STEP 6: Second design was extruded using the Boss-Extrude feature. |

![]() |
STEP 1: A new page was created for design assembly, and the design was inserted. |
STEP 2: Eight parts were created for Design 1, and four parts were created for Design 2. |
![]() |
![]() |
STEP 3: Both designs were assembled together to ensure that they fit properly according to the measurements. |
STEP 4: The final design was assembled. |
Cardboard & Design Size and Kerf Measurement
As we had explored in our group assignment during the speed pattern testing, we used a power setting of 70 and a speed of 30 on the laser cutter. This resulted in a clean and accurate cut, and we observed a kerf of 0.30 mm. Following the same pattern, I designed my individual assignment with a material thickness of 3 mm. However, I selected cardboard with an actual thickness of 3.33 mm to compensate for the 0.30 mm kerf expected during the laser cutting process. For my individual work, I again set the laser cutter to 70% power and 30 speed, and then initiated the cutting process.

Cardboard Size is 3.34mm |
Design Size is 3mm |
Kerf Calcuation
After completing the design cutting, I measured the cut section using a Vernier Caliper. Initially, I had designed the part to be 3 mm thick. However, after cutting, the measured thickness was showing 3.34 mm. This confirmed that we had already checked the cardboard thickness beforehand, which was 3.33 mm. Accordingly, I designed it to be 3 mm, taking the expected kerf into account. As you can see in the images below, the kerf appears to be approximately 0.34 mm — slightly more than the expected 0.30 mm.

Vinyl Plotter Design, Creation and Cutting Process
![]() |
![]() |
STEP 1: First, I opened Inkscape, typed the name, and set its dimensions. |
STEP 2: Then, I went to the file menu, clicked on "Open New File," imported the logo into Inkscape, and set its dimensions. |
![]() |
![]() |
STEP 3: Next, I used the "Trace Bitmap" tool to convert the logo's raster file into a vector format, resulting in a vector logo file. |
STEP 4: Afterward, I deleted the raster file and selected the final vector file. |
Exporting DFX file from inkscape.
To ensure the file is compatible with the plotter machine’s cutting software, it needs to be in a specific format. I’ve exported the design as a DXF file, which is the preferred format for precise cutting and is fully supported by most plotter software.
Here is the process to download the file in DXF format from Inkscape.
