The Engineering Design Process
This is the first step engineers must use when beginning a new project or process.
What is define the problem?
This is the recognized number of simple machines that can be used today.
What is six?
In class, the computer and 3D printer are an example of a CAD/CAM system. What does CAD/CAM stand for?
What is Computer-Aided Design/Computer-Aided Manufacturing?
This is a power tool consisting of a circular saw blade in the middle of a large, flat plane typically used for straight cuts on large sheets of material.
What is a table saw?
This is the key distinction between a mock-up and a prototype.
What is a prototype works and a mock-up doesn't?
This type of model is typically built first because it is cheaper and faster to build than those made further into the design process.
What is a mock-up?
This simple machine consists of an angled surface used to make pushing (or pulling) loads to higher levels.
What is an inclined plane?
Most manufacturing processes utilize steps to check that products being created meet the minimum standards required to be sold to consumers. This process, abbreviated "QC", stands for this.
What is quality control?
This stationary power tool consists of a long, thin blade that revolves between two wheels, resulting in continuous cutting action and typically used for cutting curves or angles on smaller workpieces.
What is a band saw?
The ability to get the maximum desired result with a minimum of wasted effort or input is called this.
What is efficiency?
Early in the design process, This step involves engineers using computers, the internet, etc. to learn as much about a project or problem as possible before they begin figuring out how to solve it.
What is research?
Of the six simple machines, which two are the other four essentially just different applications of?
What are the inclined plane and the lever?
Used with computer-controlled machinery, the acronym "CNC" stands for this.
What is Computer Numerical Control?
This portable power tool consists of a circular, toothed blade used to make long, straight cuts in a workpiece.
What is a circular saw?
This type of foundation is most commonly used with residential structures in areas prone to earthquakes.
What is a slab?
This step of the design process often involves choosing a single solution to move forward with due to limitations on time, materials, and budget.
What is selecting an approach?
In general, all simple machines are used to modify one or both of these two aspects of a force.
What is magnitude or direction?
Used for a manufacturing system that emphasizes efficiency by producing materials and parts on an as-needed basis, the acronym "JIT" Manufacturing stands for this.
What is "Just in Time"?
This portable power saw uses a reciprocating (up-and-down) motion to make precision cuts on material in a variety of shapes or patterns and is typically used for detailed work.
What is a jigsaw?
In woodworking, rip cuts move with (parallel to) this part of the wood and cross cuts move against (perpendicular to) it.
What is the grain of the wood?
The proper term to describe a circular process that can be repeated to continually improve a product, like the engineering design process, is this.
What is iterative?
This term describes the ratio of force or distance going into a machine compared to the force or distance coming out of a machine.
What is mechanical advantage?
This acronym is used for computer software that is able to simulate stress on a model to find points of weakness before actually creating the physical product.
What is FEA (Finite Element Analysis)?
This tool, commonly found on table saws, is used to ensure a long cut parallel to the wood grain is perfectly straight.
What is a rip fence?
In machining processes, this custom-designed tool is often used in presses to cut, shape, or form materials (usually metals) into a specific shape.
What is a die?
