Assembly Design
A group of parts that are connected and form one unit.
What is assembly?
Two areas of one or more parts that contact each other.
What is mating?
A heavy solid line used on a drawing to represent the outline.
What is an object line?
The process of taking something apart and analyzing its workings in detail.
What is reverse engineering?
A process used to analyze something with the goal of identifying then repairing a problem.
What is troubleshoot?
A hole that has the same diameter along its length and passes completely through the object.
What is a through hole?
A function that represents the distribution of variables as a symmetrical bell-shaped graph.
What is normal distribution?
Lightly drawn line to guide drawing other lines and shapes.
What is a construction line?
A group of interacting, interrelated, or interdependent elements or parts that function together as a whole to accomplish a goal.
What is a system?
Information or signals entered into a computer system. Examples of an input device are a button, keys on a keyboard, touch screen, and accelerometer.
What is input?
A hole that is drilled to a specific depth and does not pass completely through the object.
What is a blind hole?
The digits in a decimal number that carry meaning contributing to the precision or accuracy of the quantity.
What are significant digits?
A heavy dashed line that represents an edge that is not directly visible.
What is a hidden line?
The action or actions that an item is designed to perform.
What are functions?
A device, system, or object which can be viewed in terms of it inputs and outputs, without any knowledge of its internal workings.
What is a black box?
A measuring instrument having two adjustable jaws typically used to measure diameter or thickness.
What is a dial caliper?
This rule states that for a normal distribution, nearly all of the data will fall within three standard deviations of the mean.
What is Empirical rule?
A line that defines the center of arcs, circles, or symmetrical parts. It is half as thick as an object line.
What is a center line?
A step in the reverse engineering process which identifies the necessary activities or actions of components and subsystems to turn available inputs—such as materials and energy—into desired output.
What is function analysis?
A sheet used to gather and organize data once as a product is disassembled.
What is a product disassembly chart?
A template for a sheet that gives general information about the drawing. It typically include 2D geometry, text attributes, and images.
What is a title block?
A strategy in which geometry is defined in such a way that changes produce desired, predictable results.
What is design intent?
A thick broken line with arrows on a technical drawing that indicates the location of an imaginary cutting plane and the view direction used to create a sectional view of an object.
What is a cutting plane line?
Making the best or most effective use of resources to get the best possible solution.
What is optimizing?
The process of creating a solid model or three-dimensional object using a modeling and design application on a computer.
What is 3D modeling?
