PPT 103 - Inspection



5.0 Credits
Delivering quality efficiently is the key to strong manufacturing. To be competitive, today’s plastic process technician must be able to effectively inspect parts in the shop with a variety of methods and instruments. This course focuses on the science and skill of measuring and inspection. They will learn to verify dimensions of size and position, surface finish, material hardness, threads, and other important elements. Apprentices will have hands-on practice using a variety of measuring instruments such as micrometers, calipers, precision gages, and coordinate measuring machines (CMMs). Apprentices will also learn techniques for inspection planning, first article inspection, in process inspection, and statistical process control. Instructors will reinforce the theory and technique of accuracy, precision, and repeatability to help students develop an uncompromising attitude towards good inspection technique. Note: This class is part of an AJAC apprenticeship program.
Prerequisite PPT 102.
Course-level Learning Objectives (CLOs)
Upon successful completion of this course, students will be able to:

  1. Demonstrate proper calibration, care, and use of measuring tools such as micrometers, calipers, thread wires, indicators, coordinate measuring machines (CMMs), and gauge blocks.
  2. Evaluate machined part dimensions, surface texture, material hardness, and threads for quality.
  3. Design a layout of a machined part based on an engineering drawing.
  4. Describe the uses and applications of CMMs.
  5. Apply inspection techniques using the principles of geometric dimensioning and tolerancing (GD&T).
  6. Describe material hardness testing methods.
  7. Describe the definition and purpose of statistical process control and sampling plans.
  8. Evaluate a process using statistical process control.
  9. Describe inspection planning, first article inspection, and in-process inspection techniques.
  10. Create inspection plans and inspection documentation and analyze the results.
  11. Demonstrate professionalism, critical thinking, and teamwork during in-class discussions and hands-on activities.
