Combining multiple 3D models into a single, complex model.

Pre-designed components used in engineering like bolts, nuts, and gears.

The process of creating a solution to a problem using technical principles.

Computer-Aided Design - software used to create 2D and 3D models.

Creating 3D models where changes in one parameter affect other parts of the design.

CAD assemblies support visualization of the assembly, checking functionality, interference analysis, motion simulation, generating a bill of materials, and evaluating and planning the assembly and disassembly process.

A list of all the parts and components needed to assemble a product.

Using CAD to detect collisions or overlaps between parts in an assembly.

Simulating the movement of parts in an assembly to analyze kinematics and dynamics.

Using existing CAD models of parts in new assemblies.

For Quiz 1, you need your student ID, a pencil, and a sheet of paper. No other materials are allowed. Dictionaries are provided.

Assembly drawings show how multiple parts fit together to create a larger product, highlighting the relationship between components.

A car is a complex assembly of many different parts, from the engine to the wheels and the body, shown in detailed assembly drawings.

Commonly used components in mechanical design, like bolts, nuts, gears, and bearings, that are pre-designed and easily available.

A list that identifies and specifies each individual part used in an assembly, including their quantity and material information.

A hierarchical breakdown of a product, showing how sub-assemblies and individual parts are organized.

A group of parts that are assembled together to form a smaller, functional unit.

The top level of the assembly hierarchy, representing the complete product.

A design approach where individual parts are created first and then assembled into sub-assemblies, building up to the final product.

A standard, pre-designed component that is used repeatedly in different assemblies.

A specific part used in assemblies, often a shaft or axle.

A car can be broken down into sub-assemblies like the body, wheels, and chassis, and each sub-assembly can be further divided into individual parts.

It helps to identify and categorize standard, reusable components, making it easier to understand the assembly and source these components.

Assembly models in CAD help engineers evaluate a product for function, fit, and manufacturability.

Constraints are the rules and relationships used in a CAD system to define how parts fit together, ensuring proper assembly.

These are pre-designed components like screws, bolts, nuts, washers, bearings, and gears, ready to be used in engineering designs.

Using standard parts can save time and effort during design, as they are readily available and have standardized specifications.

Bearings are mechanical components that reduce friction and support motion between moving parts in a machine.

Seals are components that prevent leaks by creating a barrier between two surfaces.

Keys are used to transmit torque and prevent relative rotation between two shafts.

Gearing refers to a system of toothed wheels designed to transmit power and motion.

A type of gearbox with a worm gear, often used in robots for precise motion control and high torque transmission. It's commonly found in robotic applications, including those at ETH.

A visual representation of a gearbox showing its individual components laid out separately, revealing their arrangement and relationships.

The way screws are used in a gearbox, typically involving threaded parts that connect and hold components together.

Joining two threaded parts, one external (male) and one internal (female), creating a strong and reliable connection.

Different screw types are used for specific applications, defined by their head shape, drive type, and thread size. Common examples are hexagon socket head cap screws and DIN 4762 screws.

Screws are categorized by their thread diameter (e.g., M1.6, M2, M3) and length (Lmin, Lmax), which are standardized for common applications.

Using pre-designed components (Normteil) in assemblies for standardization, reusability, and efficiency in design and manufacturing. They are often listed in catalogs and are readily available.
