TASK 1 REPORT

LEVEL 1

INTRODUCTORY MODULE

I Explored the basics of Computer-Aided Design (CAD) and drafting. CAD is a technology that is widely used in various industries for creating detailed and accurate drawings and designs of objects, structures, and systems. Here are some of the basics you might have learned:

• Drafting: Drafting is the process of creating detailed technical drawings, often called blueprints or CAD drawings, that represent objects, parts, or structures. These drawings are used for communication and documentation in engineering, architecture, manufacturing, and other fields.
• CAD Software: CAD software is the primary tool used for drafting and design. Popular CAD software includes AutoCAD, SolidWorks, CATIA, and many others. These programs provide a digital platform for creating, editing, and storing drawings.
• 2D and 3D Modeling: CAD allows for both 2D and 3D modeling. 2D modeling is used for creating flat, two-dimensional representations of objects, while 3D modeling allows you to create three-dimensional models with depth and perspective.
• Geometric Shapes and Tools: CAD software offers a wide range of geometric shapes and tools to create precise drawings. These tools include lines, arcs, circles, rectangles, polygons, and more.
• Layers: CAD drawings often consist of multiple layers, each containing different elements of the design. Layers help organize the drawing and make it easier to work on specific parts or details.
• Dimensioning: Dimensioning is the process of adding accurate measurements and annotations to a drawing. It helps convey the size and scale of objects and is crucial for manufacturing and construction.
• Editing and Modification: CAD software allows you to easily edit and modify drawings. You can move, resize, rotate, or delete elements, which is much more efficient than traditional manual drafting.
• Parametric Design: Some CAD programs support parametric design, where you can define relationships and constraints between elements. When one part of the design changes, other related parts automatically adjust, ensuring consistency.
• File Formats: CAD drawings are typically saved in specific file formats like DWG (AutoCAD), STL (3D printing), or STEP (standard exchange format). These formats are compatible with various CAD software and equipment.
• Applications: CAD is used in a wide range of industries, including architecture, mechanical engineering, electrical engineering, aerospace, automotive design, and more. It's used for designing buildings, machinery, products, electronic circuits, and even animations and simulations.

INTRODUCTION TO ENGINEERING DRWAINGS

ORTHOGRAPHIC AND ISOMETRIC PROJECTIONS:

• Orthographic Projection: Orthographic projection is a technique used in CAD to represent three-dimensional objects in two-dimensional views. It provides a set of multiple 2D views (such as top, front, side) to fully describe an object's shape and size.
• Isometric Drawing: Isometric drawings are a form of 3D representation in 2D space. They use a special projection method that allows you to see all three dimensions of an object without perspective distortion.

2D DRAWINGS IN CAD

Designing 2D drawings in CAD (Computer-Aided Design) is a fundamental aspect of engineering and design. It involves creating detailed, scaled representations of objects, components, or plans. These drawings serve as essential documentation for manufacturing, construction, or reference purposes.

2D DRAFTING.

Sierpenski Triangle (LEVEL 2)

• It's created by dividing an equilateral triangle into smaller triangles, and the process repeats infinitely, forming a self-replicating pattern of smaller triangles within itself. This fractal is widely used in math, computer graphics, and art to illustrate recursion and fractal concepts.

3D MODELLING

TASK 1 - ALLEN KEY

TASK 2 - 3 MACHINE PARTS

SOLID MODELLING

DESIGN A SIMPLE AEROFOIL FOR AN HTOL AIRCRAFT USING FUSION 360 Designing an aerofoil on Fusion 360 software is a practical application of CAD tools for aerospace and engineering purposes. Fusion 360 offers a comprehensive set of features for 3D modeling, making it well-suited for creating complex shapes like aerofoils. By using Fusion 360, you can precisely define the aerofoil's geometry, adjust parameters such as chord length, thickness, and camber, and even perform simulations to analyze its aerodynamic properties. This process allows you to visualize and refine your aerofoil design efficiently, making Fusion 360 a valuable tool for aerospace engineers and enthusiasts alike.

SURFACE MODELLING:

PROPELLER

• Design of a toroidal (doughnut-shaped) propeller for marine applications, aiming to improve efficiency, maneuverability, and minimize environmental impact.
• Background: Conventional propellers have limitations in terms of efficiency and hydrodynamic performance. A toroidal propeller offers the potential for a more efficient and environmentally friendly propulsion system.

ORGANIC DESIGNS USING FORMS

Designed a hollow vase using a cool tool led \ forms " in Autodesk Fusion 360. This tool lets me design, edit, move, rotate, and shape the product really smoothly, adjusting its size however I need. Once I finish designing, i used another cool feature called rendering , It helps me see how the object would look after it's made. I can see it from different angles and make it look like a real picture. I can even choose different materials like wood, plastic, glass, or even polymer. What's even more interesting is the lighting part... I can see how the object would look in different types of light. The main use of it is to create a realistic image of designed object that a customer or manufacture can use for his purpose. it's important for things like interior designing , advertising , architecture and various furniture design too

3D PRINTING

IT INVOLVES FEW FOLL0WING STEPS :

• Firstly preparing the 3d printer (ON) and load the polylactic acid filament (PLA).

• Making sure the plate is clean and levelled.

• Slicing the model using any slicing software at marvels we prefer creality slicer as it is compatible with the printer.

• Get the G code done after slicing , next adjust the bed temperature around 50 to 60 degree centigrade.

• nozzle temperature depends on the material for PLA: 200 , PLA+: 215

• and set the model to print.

MAKING BASIC GATES AND OR DESIGNS USING NPN TRASNISTORS .

AND GATE

AND Gate: Think of an AND gate like a bouncer at a nightclub. It only lets you inside if both conditions are met:

• You have a VIP pass (Input 1).
• You're wearing a red shirt (Input 2). If you don't have both the VIP pass and the red shirt, you won't get in. So, an AND gate produces an output (you getting inside) only when both inputs are true. https://www.tinkercad.com/things/1OyWb0W36OB

OR GATE

OR Gate: An OR gate is a bit more relaxed. It's like a restaurant with multiple entryways. You can get in through any of them:

Front door (Input 1). Side door (Input 2). If you use the front door or the side door, you can still enter the restaurant. In other words, an OR gate produces an output (you getting inside) when at least one of the inputs is true. https://www.tinkercad.com/things/h2If6BVcxay

N CHANNEL MOSFET

An N-Channel MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a type of field-effect transistor that is widely used in electronic circuits.

• It consists of a semiconductor material (usually silicon) with three terminals: gate (G), drain (D), and source (S). When a voltage is applied to the gate terminal, it creates an electric field in the channel (between the source and drain), allowing or blocking the flow of current. In N-Channel MOSFETs, the majority charge carriers are electrons, and applying a positive voltage to the gate terminal relative to the source terminal allows current to flow from the drain to the source.
• It acts as an electronic switch, controlling the flow of electrical current in electronic devices and circuits, and is commonly used in amplifiers, switching applications, and voltage regulation circuits.
