3. Computer controlled cutting¶
This week I worked on defining my final project idea and started to getting used to the documentation process. hello
Parameteric Design¶
Parametric design is a process that uses algorithmic thinking to enable the expression of parameters and rules that, in turn, define and clarify the relationship between design intent and design response. This method allows designers to use parameters, such as dimensions, material properties, or performance criteria, to generate a wide array of possible solutions through computational means. By adjusting these parameters, designers can quickly iterate through various design alternatives, leading to innovative and efficient outcomes that might be difficult to achieve through traditional design methods.
Press-fit¶
Press fit is a method of fastening two components together by using friction. This is achieved by designing one part to be slightly larger than the hole into which it is inserted. When the larger part is pressed into the smaller hole, the resulting friction between the surfaces creates a tight and secure connection without the need for adhesives, welding, or additional fasteners. This method is commonly used in mechanical engineering and manufacturing for assembling components such as gears, bearings, and dowel pins, ensuring a strong, reliable fit that can withstand significant loads and stresses.
Cuttel¶
- go to project on the left side of the screen.
- click on the plus sign to add a parameter and name it
- when editting size, write the parameter’s name
Fusion360¶
- go to modify –> click on –> plus sign –> add parameter.
- after drowing, go to create –> dimantion choose –> write parameter’s name.
Examples¶
1- Furniture Assembly: Many flat-pack furniture pieces use wooden dowels that are press-fitted into pre-drilled holes to join parts together without screws or nails.
2- Automotive Components: Parts such as wheel bearings are press-fitted into hubs, ensuring a secure and precise fit essential for the vehicle’s performance and safety.
3- Electronic Connectors: Many electrical connectors use press fit pins to secure the connection between the connector and the printed circuit board (PCB), providing reliable electrical contact without soldering.
Vinyl Cutting¶
In this assignment, I used Silhouette Cameo, and cricut. It has great features like touch screen, its settings doesn’t depand on material and you can cut electronics board. One drawback, the software took along time to download it.
Silhouette¶
-
Download Silhouette Studio
-
Open .png file
-
Go to Trace –> select & adjest –> click on trace
-
press Load cut mat & put the mat in the right place
* Change the cutting head
- Go to send –> Line –> change material –> connect through USB –> send
- Press Unload –> remove undesiered parts –> use transparint sticker
cricut¶
-
Download Silhouette Studio
-
Open .jpg file
- Go to New Project –> Upload –> Upload Image –> choose file
- press contour than select the sketch. After press Make, than chose mat. finally we conect the cricut machean and start prent.

Saftey Measurment¶
- make sure nothing is behind and front the cutting machine.
- Don’t put your hand inside the machine while cutting.
Laser Cutting with Cardboard¶
- Drow the desired shape and add dimantions
- Add Parameters
-
Use extrude to make sure the design is fitting.
-
export .dxf and e-mail it to fablab
-
Import and select .dxf file
- Repeat the design
-
From group assignment: Material is cardboard, Thickness 1.6mm, power is 55, speed is 80.
-
Select the desire design & asign the color\speed\power\mode
- Download it to the machine
- insert the cardboard –> define orgin –> Click start
Saftey Measurment¶
- Push the red button if anything goes wrong.
-
Make sure you know where fire extinguisher and first aid kit.
-
Test the mechine for readiness.

Code Example¶
Use the three backticks to separate code.
// the setup function runs once when you press reset or power the board
void setup() {
// initialize digital pin LED_BUILTIN as an output.
pinMode(LED_BUILTIN, OUTPUT);
}
// the loop function runs over and over again forever
void loop() {
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
