Surface Texture: Specification and Control C1110

Surface texture is one of the most important topics in today"s world of design, development and performance. As tolerances are shrinking and performance demands are increasing, surface texture is rapidly becoming one of the most important aspects of engine and vehicle performance. Every moving component on a vehicle or engine is influenced by surface texture in one or more of the following ways: vibration, sealing, adhesion, traction, emissions, safety, durability, wear/failure analysis. Many of the industry"s top warranty issues (leaks, noise, vibration, etc.) are a direct result of surface texture implications. Rather than focus on the theories of surface texture, this course will focus on the applications of these concepts to automotive applications - thereby giving the attendees tools that they can immediately use as they solve automotive problems such as cylinder bores and emissions control, crankshafts, camshafts and early engine failures, brakes and NVH, wheel bearings and vibration, gaskets and sealing, bearings and durability, pistons and durability, and shaft straightness and vibration.
Learning Objectives

By attending this seminar, you will be able to:

  • Communicate clear descriptions of surface texture in reports and product documentation
  • Recognize roughness and waviness impacts on components
  • Recognize measurement errors and avoid misinterpretations of results
  • Specify surface texture according to ISO 1302
  • Identify and specify functional wavelength regimes for surface texture

Who Should Attend

This topic bridges all fields within the automotive industry and is designed for engineers and technicians involved in: the specification of mechanical systems and components; failure analysis and warranty; quality control and measurement functions, manufacturing and process development. The areas of interest could include: sealing, sliding, cosmetic appearance, friction, leakage and more.


Participants should have a basic knowledge of mechanical terms such as friction, sealing, wear, etc.


"Extremely good introduction and overview of surface texture control. Working in the clutch development line of work, surface texture control is very important for performance. This class gave me a lot of valuable insight."
