Core Course Performance Objectives (CCPOs)

  1. Interpret and develop primary and secondary auxiliary views for shop fabrication drawings.  (CCC 1, 2, 5, 6; PGC 1, 3, 4, 5)
  2. Interpret and apply dimensioning techniques to various engineering drawings using different dimensioning methods.  (CCC 1, 2, 5, 6; PGC 1, 3, 4, 5)
  3. Apply required fits and tolerances to various shop drawings.  (CCC 1, 2, 5, 6; PGC 1, 3, 4, 5)
  4. Interpret and specify surface textures and related notes to different engineering drawings.  (CCC 1, 2, 5, 6; PGC 1, 3, 4, 5)        

See Core Curriculum Competencies and Program Graduate Competencies at the end of the syllabus. CCPOs are linked to every competency they develop.

Measurable Performance Objectives (MPOs)

Upon completion of this course, the student will:

  1. Interpret and develop primary and secondary auxiliary views for shop fabrication drawings.
    1. Describe the purpose of an auxiliary view.
    2. Explain how an auxiliary view is projected.
    3. Discuss and draw viewing-plane lines related to auxiliary views.
    4. Solve for the true shape of an angled surface using an auxiliary view.
  2. Interpret and apply dimensioning techniques to various engineering drawings using different dimensioning methods.
    1. Identify and use common dimensioning systems.
    2. Apply proper specific notes for manufactured features.
    3. Place proper local and general notes on a drawing.
    4. Apply angular, callout, overall, limited length, and area dimensions.
    5. Dimension and recognize standard symbols for curved features.
    6. Define and dimension chamfers, threads, drills, tapers, knurling, and keyways.
    7. Apply tabular, arrowless, rectangular coordinate, and polar dimensioning.
  3. Apply required fits and tolerances to various shop drawings.
    1. Analyze part features in terms of integral geometric shapes to facilitate concise dimensioning within prescribed tolerances.
    2. Solve tolerance problems, including limits and fits.
    3. Prepare completely dimensioned multi-view drawings with tolerances.
  4. Interpret and specify surface textures and related notes to different engineering drawings.
    1. Recognize finish marks, general symbols and notes, and ANSI basic surface texture symbols.
    2. Identify the differences of surface roughness on real mechanical pieces.
    3. Accurately draw surface finish symbols and related notes on drawings.

Evaluation Criteria/Policies

The grade will be determined using the Delaware Tech grading system:

90-100 = A
80-89 = B
70-79 = C
0-69 = F
Students should refer to the Catalog/Student Handbook for information on the Academic Standing Policy, the Academic Integrity Policy, Student Rights and Responsibilities, and other policies relevant to their academic progress.
