Engineering & Technical Drawings

What is an engineer? • There are many different types of engineers. They are all involved with design and building. Different types of engineers deal with the design and building of different aspects of technology. • http: //www. youtube. com/watch? v=BPZXg. Qw I 8 Ec

Why build machines? • Machines have been designed and built to help solve some problems. They make life easier by reducing the amount of work we have to do. Many tools/machines/systems have been designed to help solve different problems.

Design process • This consists of three phases: 1. Design: identify a need, make a prototype, test prototype. . . patent! 2. Production: manufacture the object according to standards outlined in the manufacturing process sheet (follow the steps!) 3. Market the product: sell it, discard/recycle it

Specifications When we build something, many things must be considered so that the tool/machine will meet the needs, function correctly and not be too expensive. What are the requirements for manufacturing, use and maintenance? What standards does it have to meet? What are its characteristics? What are the manufacturing costs? Deadlines to complete project? Is it feasible or viable (can it be done)?

Specifications: • We must consider the following specifications: • Physical, Technical, Economic, Industrial, Human, Perspective.

Technical Diagrams • The Design plan is a diagram that describes an object in a simple way and describes how it works. These plans must indicate the main components, the motion involved (using symbols), the useful force developed by the object and the direction in which the force is applied.

Design plan

Technical Diagrams • The Technical Drawing shows the exact measurements and configuration. We can manufacture the product by looking at this diagram. It must include the parts directly involved in the object’s function, other parts, and links between the parts (using the standard symbols).

Technical Drawing

Raw Material • Found in nature (animal, plant/trees, minerals, water) • Modified to make materials and equipment

Material • Raw material is transformed into material

Equipment • Instruments, tools or machines
