Seminar 102A<strong>Dimensional</strong> <strong>Metrology</strong>: <strong>Applications</strong> <strong>and</strong> <strong>Techniques</strong>Overview:This two-day course presents the science of measurement for students of dimensional metrology.It is intended for anyone who wishes to learn the basic tools <strong>and</strong> techniques required for reliablemeasurement. The course covers a variety of related topics to apply measurement principles with“best practices” <strong>and</strong> presents fundamental considerations for the proper selection, application, <strong>and</strong>care of typical measurement systems.A principle course objective is to develop awareness, knowledge <strong>and</strong> basic skill necessary for thereliable measurement applications. Technical terms <strong>and</strong> principles will be covered in depth. Theclassroom will provide opportunities for some h<strong>and</strong>s-on experience, <strong>and</strong> the instructor will workwith the attendees to demonstrate the proper use of common h<strong>and</strong>-held measuring tools.Measurement applications for Geometric Dimensioning <strong>and</strong> Tolerancing (GD&T) <strong>and</strong> assessmentof measurement quality will be introduced.I. Introduction – manufacturing challenges <strong>and</strong> modern measurement.II. Basic Conceptsa. Language of measurement, types of data, variable versus attribute, the“usefulness” of datab. Units of measure, expression of inch <strong>and</strong> SI metric systemsc. Process of measurement, the properties of reliability <strong>and</strong> uncertaintyd. Fundamental Laws of <strong>Metrology</strong>: Abbe’s Law, Comparator Law <strong>and</strong> otherse. St<strong>and</strong>ards <strong>and</strong> traceability, absolute length st<strong>and</strong>ard, NMIsf. Temperature issues <strong>and</strong> control for dimensional measurementg. Direct versus comparison measurementh. Introduction to a universal Error modelIII. Measurement of GD&T (ANSI Y14.5)a. History, concerns <strong>and</strong> conflicts of GD&T measurementb. Geometric tolerances – size, form, orientation, location, runout, profilec. Underst<strong>and</strong>ing the Feature Control Framed. Datum, datum reference frame, <strong>and</strong> modifierse. Attribute <strong>and</strong> functional gaging for GD&Tf. Review of variable measurement methods for GD&TIV. References <strong>and</strong> st<strong>and</strong>ard gagesa. Gage blocksb. Surface platesc. Cylindrical mastersd. Optical flats <strong>and</strong> parallelsV. Basic “H<strong>and</strong>” Tools – mechanical <strong>and</strong> digital, proper use <strong>and</strong> applicationsa. Calipersb. Micrometersc. Indicators (dial <strong>and</strong> test)VI. Attribute gages – class, selection, <strong>and</strong> proper usea. Cylindricalb. Threadc. Radius
VII. Introduction to Advanced Measurement Systemsa. Optical Comparator (profile projector)b. Cylindrical form measurement - straightness, flatness, circularity (roundness) <strong>and</strong>cylindricityc. Surface finish <strong>and</strong> basic parametersd. Coordinate Measuring Machines (CMMs)Introduction to Gage R&R (MSA) <strong>and</strong> measurement uncertaintyCourse Materials:The "<strong>Metrology</strong> H<strong>and</strong>book", 2 nd edition, 280 page, full color reference book, written by NobuoSuga, Mitutoyo Institute of <strong>Metrology</strong>, is included with this course.Additional materials provided by the Instructor.Instructor:Gordon Skattum is an ASQ Fellow, CCT, <strong>and</strong> Senior Member of SME with over 36 years inquality engineering <strong>and</strong> manufacturing technology. He is a recognized expert in dimensionalmetrology, measurement systems analysis, <strong>and</strong> process control. As a member of the TechnicalWriting Group for the AIAG, he provided significant contributions to the automotive industryMSA Reference Manual, 3rd edition.CURRICULUM:DIMENSIONAL METROLOGY is a 2-day class, followed by Gage Calibration Systems& Methods, also a 2-day class. These 4 days are held consecutively in the same week ateach location.Integrated GD&T is a 4-day class that follows the week of <strong>Dimensional</strong> <strong>Metrology</strong> <strong>and</strong>Gage Calibration Systems & Methods at each location, within a week or two.H<strong>and</strong>s-On Gage Calibration is a 3-day class held every other month at our world-classCalibration Laboratory in Elk Grove Village, IL.Measurement Uncertainty is a 2-day class in which we hold once a year at mostMitutoyo locations.On Dem<strong>and</strong> courses in CMM, MSA, Gage R&R, Surface Finish <strong>and</strong> Form Measurementcan be provided.Mitutoyo <strong>and</strong> its Institute of <strong>Metrology</strong> is a worldwide organization. We are proud to state thatmore than 200,000 engineers have attended our metrology seminars over the years.
