Surface Roughness Measurement, Validation and Improvement

Date : 17 to 18 November, 2021

Time : 1340 Hrs to 1700 Hrs


In the precision engineering industry, the functional properties of a component are affected by the boundary areas (or the surface) of the component. This aspect becomes all the more important when the surface comes in contact with the surface of the mating component and is operationally related to it. The unceasing demand for increased performance, interchangeability and functional reliability has resulted in shrinking of tolerances for a precision component. As the tolerances shrink the surface aspects of the component become more and more dominant and the dimensional aspects of surface finish become exceedingly important. A serious quantitative study of the quality of a surface becomes an inseparable part of component design, manufacture and inspection to ensure proper functional behaviour of the design.

Additionally, to achieve the desired finish, the entire machining system comprising the type of machining process, machine tool, work holding, cutting tool and machining parameters needs to be considered appropriately.

Keeping this in view, IMTMA is organizing an online training on "Surface Roughness Measurement, Validation and Improvement"

In addition to measurement / validation, session will cover the tools and techniques towards improving surface finish in machining. Live video demo in CNC machines will be shown to stress the Do’s and Don’ts in machining.

Focus Areas

  • Introduction to Surface finish
  • Importance, its occurrence and effects
  • Assessment of Surface finish - Systems and Parameters
  • Preferred values & relation between various parameters
  • Surface finish & manufacturing economy; surface finish & class of fits;
  • Surface finish obtainable by different manufacturing processes
  • Measurement of surface finish - mechanical, optical and electric/ electronic methods & instrumentation
  • Measurement of surface finish of inaccessible surfaces
  • Dependence of Surface Roughness on Machining Parameters
  • Proper selection of tools and machining parameters for improving finish
  • Demo on improvement of surface finish in Turning & Milling applications.

Key Take Aways

After undergoing the programme, the participants will be able to -

  • Appreciate what is finish of a surface and why is it important.
  • Get to know what factors influence a surface and its finish.
  • How to express surface finish and units of measurement.
