Catalog Description:
Untitled document
Metrology is the study of the science of precision weights, measurement, and inspection used in manufacturing. Students will become familiar with all types of handheld electronic and optical measuring devices. Visits to local industries utilizing Coordinate Measuring Machines (CMM) and related inspection devices are included. Print reading will be used as a vehicle to support Geometric Dimensioning & Tolerancing (GD&T) inspection standards. Class also includes study of International Standards Organization (ISO), Statistical Process Control (SPC), and American Society of Mechanical Engineers (ASME) inspection standards.

Prerequisites/Corequisites:
Completion of or concurrent enrollment in MACH 51A; and Course Completion or Concurrent Enrollment in IED 90A or APTECH 90A


Recommended Preparation:
Eligibility for ENGL 100 or ESL 100 or appropriate placement based on AB705 mandates
