Description
Metrology is the science of measurement. Everything
that a manufacturer can do to improve the quality of both product and process depends
upon accurate measurement. The seminar instructor teaches the correct use and care
of measuring equipment commonly used in precision machine tool metalworking occupations
and by quality assurance personnel and operators in any manufacturing facility.
English units of measure will be used, although use of the metric system by participants
who use metric measurements on the job can be accommodated.
You will learn
- What dimensional metrology is.
- Reasons and uses for measurement.
- The definitions of precision, accuracy and reliability.
- How to read a 6" steel rule.
- How to read, care for, use and calibrate vernier/dial measuring tools.
- How to read, care for, use and calibrate micrometers (outside, inside).
- How to read, care for, use and calibrate dial indicators.
Who will benefit
- Operators responsible for sampling/charting
- Quality assurance personnel
- First-line supervisors and managers
- Machine tool metalworkers

Your instructors
Joseph Gladkowski is the senior faculty person for the Machine Tool Technology
Program at Joliet Junior College and has taught college classes since 1995. He has
26 years of hands-on experience as a tool and die maker, with a concentrated interest
in die making and mold making. Joe has an A.A. from Joliet Junior College and a
B.A. from Lewis University.
Mathew Higgins is a Joliet Junior College faculty member who retired from
Caterpillar after 31 years of experience. He was a machinist for twenty of those
years, worked as a manufacturing engineer designing fixtures and tools, as a tool
analyst, and as a senior numerical control programmer. He knows the real-world demands
made on operators and has years of experience training operators. Matt served on
CAT recertification teams and customer certification teams. Prior to joining the
JJC faculty, he worked for MTH Tool (Plano), a manufacturer of turbine pumps, designing
flow layouts. Matt received an A.A.S. degree in Supervision.
