Addendum to Course Description
Vertical Milling Machines & Operations consists of the following modules:
Dial in Vice / Sweep in Head - Milling is the process of removing material using various cutters and accessories. This module will introduces the student to a variety of cutters, accessories, the use of indicators and a center/edge finder, and methods of clamping. This module will show the student how to "set-up" the milling machine to perform the precision work the machine is capable of doing.
Fly Cutter & End Mill / Square - The milling machine, if properly "set-up" is capable of squaring a block of material on all 6 sides to a tolerance of .003" or less when inspected on a surface plate with a combination angle plate and a test indicator. This module introduces the student to one method of performing this task.
PREREQUISITE SKILLS AND KNOWLEDGE:
Digital Readout / Drill, Tap, Ream - This module introduces the student how to setup, find the edge of a workpiece and drill, and thread a hole.
Turntable / Cut Radii - The turntable is used to perform circular cutting operations on the milling machine. This module introduces the student to introduces the student to the use of the boring head to bore holes into a piece of steel using the offset boring head attachment and boring bar.
Boring Head/Mill - This module will show the student how to use the boring head to bore holes into a piece of steel using the offset boring head
Intended Outcomes for the course
Upon completion of the course students should be able to:
Dial in a vise, square to .001 T.I.R., flat and perpendicular to .001 T.I.R. (total indicator reading).
Tram (or dial in) in the head to .001 T.I.R. or less.
- Square and size a block of steel to print specification, using .001 test indicator, parallels, fly cutter, end mills, and following step-by-step instructions.
- Follow instructions for using the digital readout, test indicator, parallels, drills, reamers, chamfer tool, 5/16-24 tap, and a center/edge finder, to drill and ream and drill and tap four holes.
- Cut two radii per print specifications using appropriate materials, tools, and equipment.
- Use a boring head with a carbide insert boring tool and other tools and equipment to bore a hole in a squared block of steel to print specifications.
Course Activities and Design
MCH205 will be presented by means of audio-visual presentations, demonstrations, lab experiences, and research activities. The course activities and design emphasize the development of skills and knowledge outcomes prescribed by established industry standards. The identified outcomes will be achieved by means of individual and team activities.
Outcome Assessment Strategies
POLICY - Student performance measurements are based on established industry standards. The various areas of study during the course will be evaluated by a variety of activities. Typical of those activities are the following;
1. READING ASSIGNMENTS - Information sheets, textbooks, journal articles and the learning resource center are potential sources of information that the student will reference as directed in the modules identified in the introduction.
2. PRACTICE - Completion of tasks and projects identified in the reading assignments, information sheets, journal articles and textbooks. Students are required to complete practice activities with 100% competency.
3. SELF-ASSESSMENT - Checking and evaluating the students understanding and knowledge gained through the reading assignments and practices typically done through a practice evaluation.
4. LAB ACTIVITIES - Participation in structured laboratory exercises with the emphasis on developing skills or increasing expertise in the areas of study identified in the module packets.
5. FINAL ASSESSMENT - An assessment in the form of a written exam and/or practical application that addresses the subject areas identified in the module packets. Students are required to complete final assessment activities with 85% competency.

Course Content (Themes, Concepts, Issues and Skills)
This course is based on performance outcomes. The following performance outcomes are based upon established industry standards. The student will demonstrate knowledge and understanding by completing the following activities:
- Given the operators manual, .0001 test indicator the student will:
1) Dial in a vise, square to .001 T.I.R., flat and perpendicular to .001 T.I.R. (total indicator reading).
2) Tram (or dial in) in the head to .001 T.I.R. or less.
- Given the operators manual, .001 test indicator, parallels, fly cutter, end mills, and step by step instructions, the student will square and size a block of steel to print specification.
- Given instruction for using the digital readout, test indicator, parallels, drills, reamers, chamfer tool, 5/16-24 tap, and a center/edge finder, the student will drill and ream four holes, and drill and tap four holes.
- Given the materials, tools, and equipment, the student will cut two radii per print specifications.
- Given a boring head with a carbide insert boring tool and other tools and equipment the student will bore a hole in a squared block of steel to print specifications.
