CNC 104 - Blueprint Reading for CNC Operators Credits: 5 LAB hours per week: 7.500 This class is designed to teach the student how to interpret a blueprint used in manufacturing. It will introduce the student to the layout, title block, line types, views, terminology, and abbreviations. Lessons are based on standard industry practice and will be taught in a lab setting. Course Outcomes:
- Identify common terminology used on blueprints.
- Identify common abbreviations used on blueprints.
- Identify common line styles used on blueprints.
- Identify the different sizes of blueprints.
