Core Course Performance Objectives (CCPOs)

  1. Demonstrate conventional tolerancing practices relating to conventional dimensioning. (CCC 1, 2, 3; PGC 1)
  2. Classify the various types of symbols with identification of their names, shapes, and sizes. (CCC 1, 2, 4; PGC 2)
  3. Accurately list data with respect to surfaces, points, lines, and axes. (CCC 1, 2; PGC 2)
  4. Identify the relationship between material condition symbols and the size or location of features and tolerances. (CCC 1, 2; PGC 2)
  5. Define the concepts and techniques of dimensioning and tolerancing to control the form and profile of geometric shapes. (CCC 1, 2; PGC 2)
  6. Apply the techniques needed to control orientation and runout of geometric shapes. (CCC 1, 2; PGC 2)
  7. Show location tolerances that include position, concentricity, and symmetry. (CCC 1, 2; PGC 2)

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

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.
