Course Outline for Machine Tool Technology 50
BLUEPRINT READING, SKETCHING, and CAD
Catalog Description:
50 – Blueprint Reading, Sketching, and CAD 3 units
(May be repeated 3 times)
Fundamentals of freehand sketching, reading of blueprints, interpreting of commonly used symbols, pictorial drawings, orthographic projection, geometric construction, dimensioning, and sectioning. Includes a general approach to Computer Aided Drafting (CAD). Focus on subject matter relevant to Machine Tool Technology and Industrial Technology applications and local industry requirements. Designed to provide a working knowledge of methods of graphical communication. 2 hours lecture, 3 hours laboratory.
[Typical contact hours: lecture 35, laboratory 52.5]
Prerequisite Skills:
None
Expected Outcomes for Students:
Upon completion of the course the student should be able to:
1. discuss the basic concepts of orthographic projection: how various views are developed, their positional relationship to each other on a drawing;
2. analyze an object or an isometric of an object and choose the required views necessary to accurately describe it: whether one, two, three views, or sectional view;
3. apply standard signs, accepted symbols, and drafting conventions according to accepted practice;
4. discuss manufacturing practices, shop practices, specifications, materials lists, and making of bills of materials;
5. select proper object views, take off dimensions, reproduce an exact object, drawing to scale;
6. select and implement basic dimensioning systems;
7. create solid models and drawings using CAD;
8. sketch various kinds of objects.
