Optics Valley Technical Series: Shop Floor Surface Measurements


Manufacturers of medical devices, aerospace components, automotive parts, and other precision components are continually challenged to improve surface quality. Small surface defects can dramatically affect lifetime and performance of parts. Even non-functional finish and surface defects can affect appearance, leading to part rejections and loss of market share.

This talk will provide an overview of:

  • Surface measuring technologies include hard gauges, stylus systems, and various line and area-based non-contact optical systems
  • Key system attributes to weigh when choosing the best system for a given application
  • Case studies showing how implementing instantaneous measurements on the shop floor can improve quality, yield, and labor costs, streamlining the overall manufacturing operation

A key focus will be on systems capable of measuring features from micrometers to millimeters where tolerances are increasingly tightening yet relatively few systems have high capability.

Who Should Attend:

  • Operations
  • Quality and compliance managers
  • Engineers manufacturing precision components
