Background

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.
