Course Outline

Course Objective

To provide fundamental to advanced information in applications and analysis of measurement equipment used to determine compliance to mechanical engineering drawings per the ASME Y14.5M-1994 Standard.
Course Length 3 Days
CEUs 2.4
What You Will Learn Introduction to Measurement
 

  • Measurement Error Sources
  Precision Hand Tools and Hard Gaging
 

  • Micrometers, calipers, indicators, pin & ring gages and thread gaging
  Bench Top Measurement Instruments
 

  • Height gages, bore gages, fixture gages and laser micrometers
  Surface and Form Instruments
 

  • Profilometers, contour measurement, roundness and cylindricity systems
  Optical Measurement Systems
 

  • Optical comparators, toolmaker’s microscopes, viewing systems and video measurement systems
  Contact Coordinate Measuring Machines
 

  • Manual & automatic CMMs, single point touch sensors & scanning sensors and measuring arms
  Multi Sensor and Hybrid Coordinate Measuring Machines
 

  • Video sensors, laser sensors, white light interferometers and micro probes
  Methods for Analyzing and Interpreting Data Results (2D & 3D)
 

  • PC-DMIS, Measure-X, MeasureMind, VMS & SmartProfile Software

  • Working with CAD and Measurement Data (Point Clouds)

  • Understanding Least-Squares -vs- Minimum-Zone Fitting

  • Understanding Criticality of Simultaneity Requirements within ASME Y14.5 Standard
  Measurement Uncertainty/Traceability

 

  • Gage Repeatability & Reproducibility (corrected and uncorrected error sources)

  • Limitations of GR&R and Benefits of Measurement Uncertainty

  • Step by Step Approach in Calculating Measurement Uncertainty

  • Task-based -vs- Feature-based Measurement Uncertainty

  • Traceability (NIST, U95)
  In each subject group an overview of the tools is followed by a demonstration of best application practices and a discussion of calibration issues and measurement uncertainty factors. Each subject session is concluded with a hands-on lab activity.
  Various parts will be utilized during this seminar to provide the greatest understanding of measurement technology applicable to multiple industries. Students are encouraged to bring a part (with CAD modal and drawing) that represents their measurement challenges (non-confidential).

Who Should Attend

This course is for those who require a greater understanding of the state of technology in measurement systems used for the measurement of components and assemblies dimensioned and toleranced per the ASME Y14.5 standards from an advanced applications and analysis perspective. Specifiers of engineering requirements as well as specifiers of manufacturing processes and measurement applications will greatly benefit. Machinists, toolmakers, designers, senior inspectors, senior technicians and engineers (all levels).
 

Due to the direct hands-on training in this course we limit each session of this course to 20 participants. Limiting the number of participants allows us to maximize the amount of time each student will be able to have hands-on utilization of each measurement instrument.
