This three-day course on Machine Tool Performance Applications provides the fundamentals for grading the required performance of machine tools, testing to meet these grades, and correction techniques to improve performance.

Classroom lectures provide an introduction to metrology principles and on-machine demonstrations of tests from the latest ISO 230 Standard using Electronic Levels and Gage, Laser Interferometer, Telescoping Ball Bar, and Spindle Analyzer complement the fundamentals.

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, and technicians 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
  • machinists


What You Will Learn

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

  • assign machine performance grades (AAA to C) based on manufacturing needs and machine age
  • assess, characterize and understand the accuracy errors of machine tools
  • identify the necessary tests for specific machine errors and select the appropriate test equipment
  • create specifications based on standards
  • prescribe acceptance test procedures
  • compare the accuracy of similar machines and predict performance
  • make informed purchase decisions
  • discover the importance of proper foundations and machine mounting
  • understand and measure environmental effects
  • identify adjustments to improve performance
  • understand the relationship between machine performance and on-machine measurement
