Dimensional Inspection, also known as Metrology

Dimensional Inspection (Metrology)


Dimensional Inspection (Metrology) Lab PhotoThis in-depth Dimensional Inspection (Metrology) Program covers all of the necessary topics to enable students to become a specialized quality inspector in a precision manufacturing or design environment. Students will acquire skills such as blueprint reading, part inspection, coordinate measuring machine (CMM) operation and programming, and geometrical dimensioning and tolerancing. With the use of precise inspection equipment, students will verify part quality and document results for quality control.  Classes take place in well lit, clean, and climate controlled laboratories.

Graduating students have the opportunity to become inspectors who have a key role in product development and verification within advanced manufacturing companies.  This program is ideal for those wishing to quickly enter the workforce as it can be completed in two semesters.

Program Objectives

Dimensional Inspection, also know as Metrology is offered at DCCThe Dimensional Inspection (Metrology) program provides specialized training in the area of precision dimensional inspection specifically designed to prepare you for a career as an inspector in a high precision manufacturing company.

Students in the program learn how to:

  • Interpret engineering drawing
  • Accurately and consistently conduct precision bench inspection
  • Accurately inspect precision components based on geometrical dimensioning and tolerancing principles
  • Operate and program Coordinate Measuring Machines (CMM)
  • Operate vision inspection equipment

The following occupational titles represent examples of possible employment opportunities:

  • Quality Control Technician
  • Quality Control Inspector
  • Calibration Technician
  • CMM Programmer
  • Quality Engineer Technician
