Todays Coordinate Measuring Machines (CMMs)
offer unprecedented speed, accuracy, and flexibility for
dimensional metrology, data collection, and geometric or
statistical analysis. From the smallest job shops to the
largest multinational corporations, CMMs have become
essential tools for achieving quality. But the
capabilities and limitations of CMMs vary tremendously
from one machine to another.
Introduction to Coordinate Measuring Machines
provides an overview of all aspects of selecting and
using CMMs. Representative examples of all types of CMMs,
from a wide variety of manufacturers, are discussed. The
Seminar includes the latest information on manual and
computer controlled machines at every level of
sophistication. The content can be customized to include
information on the specific machines that are of
interest to your company.
Introduction to Coordinate Measuring Machines is
oriented toward Managers, Supervisors, Operators,
Engineers, and Quality Professionals. It consists of six
instructional units and requires approximately eight
hours for presentation. Participant materials include
copies of selected illustrations and reprints of key
Coordinate Measuring Machine articles and technical
papers. Various presentation schedules are available to
meet your requirements.
