Term
| What is necessary to create a sweep? |
|
Definition
| An axis of symmetry and determination of how the geometric features are distributed across part features of the model. |
|
|
Term
| What is a manifold model? |
|
Definition
| Models that unambiguous define a boundary btw the inside and outside of an object. |
|
|
Term
| What is bidirectional associativity? |
|
Definition
| Where changes in either the 3D model or data in the supporting application will affect the other. |
|
|
Term
| What is necessary to define a linear or radial array/pattern? |
|
Definition
Linear array-parent feature, distances btw copies and number of copies.
Radial array-axis of revolution, radius, angular displacement, and number of copies. |
|
|
Term
| What is necessary to define a mirrored feature? |
|
Definition
| Plane to mirror on and feature to be copied. |
|
|
Term
| What is a primitive model? |
|
Definition
| A model that has only a limited set of geometric primitives, which allows for only certain topologies to be created. |
|
|
Term
| What is the difference between convergent and parallel projection? |
|
Definition
Convergent projection uses a definite point to project an image on a plane.
Parallel projection-requires that the object be positioned at infinity and viewed from multiple points on an imaginary line parallel to the object. |
|
|
Term
|
Definition
| A special construction line used to share the depth dimension between the top and right side views. |
|
|
Term
| When is a miter line used? |
|
Definition
| Used at a point of intersection for lines coming to and from the right side and top views. |
|
|
Term
| What is contour dimensioning? |
|
Definition
| Places dimensioning in the most descriptive views of the feature. |
|
|
Term
| What are the different types of machined holes and how would you dimension them? What are the symbols? |
|
Definition
| Through, Blind, Countersink, Counterbore, Spotface |
|
|
Term
|
Definition
| The traditional way to describe a scale. (1:4) |
|
|
Term
| How would you determine an appropriate drawing scale for a multiview drawing? |
|
Definition
|
|
Term
| What is a working drawing? |
|
Definition
| The complete set of standardized drawings specifying the manufacture and assembly of a product based on its design. |
|
|
Term
| What is included in a complete set of working drawings? |
|
Definition
1. Detail drawings of each non-standard part.
2. An assembly or subassembly drawing showing all the standard and non-standard parts in a single drawing.
3. A bill of materials
4. A title block |
|
|
Term
| What is a detail drawing? What is an assembly drawing? What is included in each? |
|
Definition
Detail drawing-a dimensioned, multiview drawing of a single part, describing the part's shape, size, material, and finish, in sufficient detail for the part to be manufactured by the drawing alone.
Assembly drawing-shows each part of the design put together.
Include: all the parts, bill of materials, leader lines assigning each part a detail number, machining and assembly operations and critical dimensions. |
|
|
Term
| What is aesthetic design? |
|
Definition
| Is more concerned with the look and feel of a product. |
|
|
Term
| What is functional design? |
|
Definition
| Is more concerned with the function of a product or process. |
|
|
Term
| What are the roles of functional and aesthetic designs in the product development process? |
|
Definition
| Because most products have both aesthetic and functional design elements, engineers have to work together to produce a product that is pleasing to both. |
|
|
Term
| What is the role of a production manager within the engineering design process? |
|
Definition
| The person who has the ultimate responsibility for a design and its team. |
|
|
Term
| What is concurrent engineering design? How is it different from a linear design process? |
|
Definition
It is a nonlinear team approach to design that brings together the input, processes, and output elements necessary to produce a product.
The people and processes are brought together at the very beginning which isn't normally done in the linear approach. |
|
|
Term
| What is a primary auxiliary view? Why do we use them? |
|
Definition
A single view projected from one of the six principal views.
They are used to determine the true size and shape of features that would appear foreshortened in any of the principal views. |
|
|
Term
| How is an auxiliary plane of projection different from a principal plane of projection? |
