This three-day course on 5-Axis Machine Tool Metrology Applications provides the understanding and application of fundamental metrology principles specific to the testing and improvement of 5-axis machine tools. Through lecture and demonstrations, focus is placed on the importance of functionally significant tests, the proper use of terminology for describing these tests and parametric test procedures as outlined in ANSI and ISO machine tool standards.

"Excellent content, well presented, a great value." - Applications Engineer

Who Should Attend

This course is designed for a wide variety of engineers and technicians concerned with machine tool productivity and purchasing specifications. Others who should consider attending this program include:

  • managers, engineers, technicians, and machinists engaged in:
    • plant management and supervision
    • manufacturing operations
    • quality assurance, control, and maintenance
    • factory, assembly, and field service
  • machine tool builders and designers, rebuilders and distributors
  • machine tool sales, service, and testing representatives
  • technology educators


What You Will Learn

By attending this information-packed program, you will...

  • assess, characterize and understand the accuracy errors of multi-axis machine tools
  • identify the necessary tests for particular machine errors
  • create specifications based on standards
  • learn misconceptions of pitch error or axis compensation
  • communicate in terms used and understood by the machine tool community
  • prescribe the correct standard test procedures
  • compare the accuracy of similar machines and predict performance
  • make informed purchase decisions
  • discover the importance of proper foundations and machine mounting
  • identify adjustments to improve performance
  • understand the relationship between machine performance and on-machine measurement
