3. Computer controlled cutting¶

This week I worked on defining my final project idea and started to getting used to the documentation process. hello

Parametric 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 editing size, write the parameter’s name

Fusion360¶

go to modify –> click on –> plus sign –> add parameter.
after drawing, go to create –> dimension 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. It has great features like touch screen, its settings doesn’t depend on material and you can cut electronics board. One drawback, the software took along time to download it.
