These positions may describe someone charged with developing/refining prototype fabrication method for new products.
7. Job Description: Repair, install, adjust, lubricate and maintain Industrial production and processing machinery or refinery and pipeline distribution systems. Diagnose machine performance problems.
8. Job Description: Troubleshoot, diagnose and repair electronic machine control equipment. Tests and modify electrical machinery, electrical-controlled equipment, and circuitry in industrial plants and laboratories. Repair, test, adjust, and install electronic equipment, such as industrial controls, transmitters, and antennas.
9. MIG-Steel
10. Job Description: In addition to the work performed by “Machine Tool Operators” (repair, install, adjust, lubricate, and maintain industrial production and processing machinery or refinery and pipeline distribution systems & diagnose machine performance problems). Machinists in this classification setup and/or operate a variety of machine tools to produce precision parts. Edit CNC programs to optimize performance; change and adjust parameters and tooling as needed to meet dimensional and output requirements. Problem-solving machining issues when performance is not satisfactory.
11. Tuition reimbursement occurs when a company repays an employee the money that employee is spending on college tuition.
12. Attendance, timeliness, work ethic, problem solving skills, math skills, communication skills
13. Old – dirty, dark, physical labor. New – high tech, bright, computer driven, more brain work and less physical labor.

Activity6: How to Use a Dial Caliper
PURPOSE: To introduce students to the concept of precision measurement and to teach them how to use
a dial caliper.
KEY:
Caliper #1 - Large: 1.000; Small: .100; Dial: .065; Total: 1.165 inches
Caliper #2 - Large:
0 ; Small: 0 ; Dial: .046; Total: .046 inches
Caliper #3 - Large: 2.000; Small: .400; Dial: .041; Total: 2.441 inches
Caliper #4 - Large:
0 ; Small: .700; Dial: .067; Total: .767 inches
Caliper #5 - Large: 4.000; Small: 0 ; Dial: .053; Total: 4.053 inches
Activity 7: Measuring With a Dial Caliper
PURPOSE: To practice measuring with a dial caliper.
KEY: Answers will vary for objects #1 - #7. When students compare and contrast their answers, they
will vary due to minute differences in objects (for example, one dime may be worn thinner than another
dime), to dial caliper accuracy (students should set caliper to zero before measuring), and to student error.
Activity 8: How to Read a Blueprint
PURPOSE: To familiarize students with a blueprint and the standard information on a blueprint.
KEY:
1. Northern Kentucky Tech
2. Screw, Machine
3. A
4. 612453
5. 1
6. 4X
7. 0
8. HKS, 2-2-00
9. SPD, 2-6-00
10. RST, 2-8-00

Activity 10: Quality Control
PURPOSE: To understand the importance of quality control and to practice determining tolerances.
KEY:
Dimension #1: .309 Tolerance range: .304-.314
Dimension #2: .054 Tolerance range: .049-.059
Dimension #3: 1.20 Tolerance range: 1.17-1.23
Dimension #4: .159 Tolerance range: .154-.164
Dimension #5: .125 Tolerance range: .120-.130
Dimension #6: .34 Tolerance range: .31-.37
If students’ measurements fall within range, they may mark “Yes” for quality. If the measurements do not
fall within the range, they may mark “No” signifying that the machine screw does not meet quality standards. At this point, they may want to measure again to determine if they made an error while measuring.
