| Level 2:
Dimensioning and
Tolerancing of Functional Gages and Fixtures and Variables
Data Collection and Analysis
[per the ASME Y14.43-2011 Standard] |
Who Should Attend?
All persons with an interest in learning the rules,
regulations and preferred ASME and ANSI practices per the
approved standard Y14.43-2011 on the design, dimensioning
and tolerancing of GO gages, NOGO gages, Functional Gages
(to verify geometric tolerances) and Fixtures (to stabilize
parts for manufacturing and inspection). Anyone interested
in the collection and analysis of variables data using
Coordinate Measurement Machines and other measurement tools.
· Gage Designers
· Fixture Designers
· Manufacturing Engineers
· Process Engineers
· Quality Engineers
· Inspectors
· Anyone wishing to strengthen their knowledge of Geometric
Dimensioning and Tolerancing
Objectives
Participants in this seminar will learn the rules,
principles and practices of gage and fixture design,
dimensioning and tolerancing per the 2011 approved standard,
entitled Y14.43-2011 Dimensioning and Tolerancing Principles
for Gages and Fixtures, from the chairman of the Y14.43
committee, James D. Meadows. The standard on which this
seminar is based extends the information contained in ASME
Y14.5M-2009 (which is not a gaging standard). It shows the
physical embodiment of the theory of Geometric Tolerances as
it pertains to manufacturing and inspection. It teaches that
the choices we make on how we design, dimension and
tolerance gages and fixtures determines whether good parts
will be rejected and/or bad parts will be accepted.
Participants will also view and discuss the collection of
variables data from Coordinate Measurement Machines and a
wide variety of inspection equipment, then analyze the data
to determine compliance with geometric tolerances.
Participants Will Learn to Apply the Principles of:
· Gage and Fixture Design, Dimensioning and Tolerancing per
the approved Y14.43-2011 standard.
· Variables data collection methods and datum establishment
by Coordinate Measurement Machines and other inspection
tools.
· Techniques to Analyze Collected Variables Data
Course Length
This course is designed as a 3 day program with
pre-requisite background. Participants should have completed
at least a basic 3-day course in the Dimensioning and
Tolerancing of parts (per the most recent standard on
Dimensioning and Tolerancing - ASME Y14.5M-2009) or have
equivalent work experience.
