Instructional Module/Training Plan

Title

Level I CNC Machining Instructional Design

Learning Setting

The learning setting will be in a machining lab and traditional

classroom. The lab will simulate a real machine shop
environment where 80% of instructions will take place. The lab
will be equipped with 5 CNC vertical machining centers and 5
CNC turning centers. A manual lathe and milling machine will be
available to teach principles of machining.

Audience

Delivery Modality (online, hybrid,

face-to-face, and so forth)

The classroom will have a workstation/computer for each

student. Each computer will have internet access, Solid Works
aided design software, and MasterCam aided manufacturing
software. A smart board and projector will be used for
lectures/presentations.
The majority of learners will be males, approximately 80% male
and 20% female. Most students will come from poverty stricken
African American communities. Students will have a minimum 9 th
grade reading level and 10 th grade math level. Learners will best
learn through a hands-on approach, having Kinesthetic or Tactile
learning styles.
The most effective method delivery for instructions is through:
Instructor-Led
Web Based Tutorial Classes
Web Based Portfolios
Instructor-Led This course requires hands-on training using
cutting edge machine tool technology. Instructor demonstrations
and oversight of student interaction with machines are necessary
to ensure students possess the needed skills to operate
machinery safely. The average cost per machine tool is $70,000.
Improper setups and programming of machine tools can result
serious damage to machines. All student projects must be

approved and supervised by an instructor prior to running the

application.
Web Based Tutorial Classes Machining applications require
competencies in measurements, materials, safety, basic print
reading, and G-code programming. These topics are self-taught
and will be delivered through Tooling U. Tooling U is an online
web tool consisting of 30 classes in advance manufacturing.
Instructors will manage student accounts and progress. This web
tool will be used for students to demonstrate their prerequisite
knowledge for operating CNC machine tools.
Web Based Portfolios Student projects require setup sheets,
tooling sheet, and G-code programs. This web tool will be used
as a repository for students project documentation and an
approval tracking system for instructors.

Instructional Module/Training Plan

Goal

Students will demonstrate the ability to operate a Computer

Numerical Controlled (CNC) lathe and milling machine.

Two Performance-Based Objectives

Download G-code program into controller

Modify or edit g-code program
Load and measure cutting tools
Make offset adjustments during production runs
Conduct 1st piece and in-production inspections
Interpret technical drawings

1. By the end of the course students will have knowledge and

experience in setting up a CNC milling machine
independently: Prove out an instructor provided program
independently, producing a part with +/- .0005 of an inch.
2. By the end of the course, students will earn an industry
approved CNC Operator credential through the National
Institute of Metal Working Skills (NIMS): produce a NIMS
part 100% to print specifications in a proctored
environment on a machine tool and pass an online
theory exam.

Part II: Development

Attention Getter

Get attention by Establish Inclusion and Developing

Attitude of Learners through demonstrating the Need for
Skilled CNC Operators through group participation:
The Attention Getter for this training plan will begin with a
group observation of all the physical products each learner
uses in their everyday lives, e.g., cell phones, vehicles,
clothing, appliances, tools, furniture. The instructor will ask
learners to list these products in a group effort.
After the list is created, the instructor will ask the group to
briefly describe how they think each product on their list is
manufactured.
After learners complete the exercise, the instructor will
briefly describe a general process of how the products on
the list are manufactured. The instructors goal is
demonstrating a common denominator among all the
processes from the learners list. The commonality of all the
processes will include the usage of CNC Machine Tools.
This will open the learners eyes to the need of CNC
operators and the fact that every product produced in
production crosses the path of CNC operators.
Get attention by Flaunting the technology needed to
manufacture these complex components:
Next, the instructor will show a few YouTube videos of the
latest technology in CNC machine tools. The video will show
CNC machine tools making real parts used in some of the
products written in the learners list. Learners will also see
CNC operators in action and how the parts are made and
assembled into recognizable products.
Get attention by Providing evidence of wage potential:
The instruction will end by demonstrating how the high
demand for CNC operators equate to high paying jobs. The
instructor will review the Bureau of Labor Statistics for hourly
wages of skilled CNC operators.

Part III: Implementation

Instructional Strategies

Instructional Strategies:

Just-In-Time
Practice
Cooperative Learning
Generating and Testing Hypotheses

Just-In-Time This strategy supports the online self-study

delivery modality. Students are responsible for learning the
theory of machining applications through Tooling Us online
courses. Instructors will provide direct instruction according
to the needs of students. Students must understand the
instructor is a facilitator in support to their learning needs.
The teaching will be adaptive rather than a fixed lesson plan.
Practice Students must become proficient at their learned
skills. Machining projects will be completed repetitiously for
mastery.
Cooperative Learning This strategy is implemented to
have students working together to accomplish certain tasks.
Students must understand that complex machining
applications are conquered through teamwork and no one
person can master all aspects of the trade. Tasks of certain
projects will be divided among group members whereas the
success of the application depends on cooperation among
the team.
Generating and Testing Hypotheses This strategy
supports the need to predict responses to metal removal in
machining. Students must understand an experienced CNC
machinist will not have direct experience in every
application. Therefore deductive reasoning will be used for
students to predict metal responses and explain their
thinking/reasoning.
Formative Assessment

Formative Assessments:
Discussion Instructor will ask questions and
informally record student responses to drive further
instructions.
Observation Instructor will walk around the lab
while students are engaged in projects. Instructor
will ask specific questions about the skills being
addressed and record notes to drive further
instructions.
Projects Students will demonstrate knowledge
through a part performance evaluation. Grade
reports will target specific skills with heavy weight
factors to drive further instructions.

Short Quizzes Students answer a few targeted

questions. They will receive feedback promptly with
directions of what he student must study as a result
of outcome.
Essay Questions Challenge students to
demonstrate higher level thinking by asking the to
explain the rationale behind machining processes.
Closure

Conclusively, students will earn two National Institute for

Metalworking Skills (NIMS) competency-based credentials:
CNC Milling Operator
CNC Turning Operator
Students will have a basic understanding of machining
applications and machine operations. These basic skills will
prepare students to obtain entry level machine operator
positions in various job and contract machine shops.
Students will now how to interpret engineering drawing, use
and read precision measuring equipment, and safely load
and unload parts. The skills leaned in this course prepare
students for employment and prerequisites for advanced
courses in CNC machining.
