PPT 121 - Precision Machining
5.0 Credits
The apprentices will explore theory, application, and hands-on experience with precision machining practices for plastic processing. Apprentices will explore topics related to manual machine tool setup and operation, for saws, drill presses, engine lathes, milling machines, and grinders. Apprentices will also gain bench work experience, including hole-making and part finishing operation using hand tools. An emphasis will be placed on preventative maintenance and safety in the shop while operating machines and handling tools and materials. Apprentices will plan, machine, and inspect two projects: a C-clamp and a plumb bob. Note: This class is part of an AJAC apprenticeship program.
Prerequisite PPT 103.
