PPT 203 - Maintenance Machining
5.0 Credits
The apprentices will explore intermediate-level theory, application, and hands-on experience with machining practices for plastics processing. Apprentices will learn about CNC machines, drives, positioning systems, feedback methods, and sensors, as well as maintenance and safety topics. Apprentices will learn advanced techniques for operating lathes, milling machines, and other machine tools in order to create their culminating project, a gear puller, which they can use for maintenance work. Apprentices will explore additional machining topics important for industrial maintenance, such as key seats and keyways, restoring and removing threads and bolts, and fastening and assembly techniques. Note: This class is part of an AJAC apprenticeship program.
Prerequisite PPT 121 and PPT 123.
