The faculty identified the General Education Abilities critical to students success in their professional and personal lives. In every class, students are assessed on course abilities, sometimes program abilities, and, in most classes, at least one General Education Ability. Students will receive an evaluation of the degree to which they have demonstrated or not demonstrated that General Education Ability. Catalog Course Description: The second course on lathe setup, operation and practices. Topics covered include alignment, turning between centers, other operations. Cut 60 degree external threads, cut internal threads, cut tapers, cut other thread forms. Use of steady rests and follower rests.
