I need solidoworks with proper documentation and photos (project) for my resume pls not the one that is copied tnx

I need solidoworks with proper documentation and photos (project) for my resume pls not the one that is copied tnx

The task is need to complete and write projects for 3 portfolio ( Gradution project ) , and the project title is about:

“Development and Finite Element Analysis (FEA) of a Crash-Resistant Automotive Chassis.”

The project aims to design and simulate a crash-resistant chassis, focusing on energy absorption and structural integrity using FEA tools. I believe this research offers significant insights into automotive safety and structural optimization.

I have attached 4 fiels explaining what is required in it, please read the instructions with high accuracy and complete the project.

The percentage of plagiarism should not exceed 10%.

Information about refrigerator

The following are detailed questions regarding the meaning of machining, divided into fundamental, technical, application, and current technology aspects.

1. Basic & Fundamental Definition

What is the general definition of machining in the context of manufacturing engineering? (Machining is a production process using machine tools that utilizes the relative motion between a tool and a workpiece to produce the desired geometry.)

What is the main objective of the machining process? (Transforming raw materials into precision workpieces.)

Why is machining called a subtractive manufacturing process? (Because material is removed/cut to form the final product, rather than molded or joined.)

What is the difference between conventional and non-conventional machining? (Conventional uses mechanical force (a tool), while non-conventional uses electrical/chemical energy.)

2. Machining Operations & Techniques

What are the three main machining operations? (Drilling, milling, and turning.)

What is meant by depth of cut in machining? (How deep the cutting tool enters the workpiece to produce chips).

What is the function of relative motion in machining? (It allows the tool to cut material accurately).

How does non-conventional machining, such as Electrical Discharge Machining (EDM), work? (It uses sparks to erode material).

3. Tools & Machines

What are the main types of equipment used in machining? (Lathes, milling machines, CNC machines, and turrets).

What is the functional difference between a lathe (turning) and a milling machine? (A lathe rotates the workpiece, while a milling machine rotates the cutting tool).

What is meant by Precision Machining? (A machining process with very high accuracy, often used for prototyping).
