| (a) General requirements. This lab course is recommended
for students in Grades 11 and 12. Prerequisite: Precision Metal Manufacturing
I. Corequisite: Precision Metal Manufacturing II. This course must
be taken concurrently with Precision Metal Manufacturing II and may
not be taken as a stand-alone course. Districts are encouraged to
offer this lab in a consecutive block with Precision Metal Manufacturing
II to allow students sufficient time to master the content of both
courses. Students shall be awarded one credit for successful completion
of this course.
(b) Introduction.
(1) Career and technical education instruction provides
content aligned with challenging academic standards and relevant technical
knowledge and skills for students to further their education and
succeed in current or emerging professions.
(2) The Manufacturing Career Cluster focuses on planning,
managing, and performing the processing of materials into intermediate
or final products and related professional and technical support activities
such as production planning and control, maintenance, and manufacturing/process
engineering.
(3) Precision Metal Manufacturing II Lab provides the
knowledge, skills, and technologies required for employment in precision
machining. While Precision Metal Manufacturing II Lab is designed
to provide necessary skills in machining, it also provides a real-world
foundation for any engineering discipline. This course may address
a variety of materials such as plastics, ceramics, and wood in addition
to metal. Students will develop knowledge of the concepts and skills
related to these systems to apply them to personal and career development.
This course supports integration of academic and technical knowledge
and skills. Students will have opportunities to reinforce, apply,
and transfer knowledge and skills to a variety of settings and problems.
Knowledge about career opportunities, requirements, and expectations
and the development of workplace skills prepare students for success.
This course is designed to provide entry-level employment for the
student or articulated credit integration into a community college
and dual credit with a community college with completion of the advanced
course.
(4) Students are encouraged to participate in extended
learning experiences such as career and technical student organizations
and other leadership or extracurricular organizations.
(5) Statements that contain the word "including" reference
content that must be mastered, while those containing the phrase "such
as" are intended as possible illustrative examples.

lathe in a safe manner;
(B) recognize, name, and describe the function of the
primary components of a CNC lathe;
(C) perform preventative maintenance checks on a CNC
lathe such as checking all fluid levels, system pressure, tooling
wear, and component lubrication and cleaning;
(D) test the coolant for proper density and adjust
accordingly in order to reach the correct mixture;
(E) perform a power up on a standard CNC lathe;
(F) demonstrate the use of the jog controls on the
operator panel to jog the lathe's axes;
