While there is lot of emphasis on Inspection of Dimensions and Tolerances post Finish Machining the knowhow of Surface Finish or Roughness measurement tends to be largely restricted to Ra Value and its validation. There is lot more to Surface Quality than Ra value, in terms of range of Parameters, how it depends on Machining Parameters, technologies to improve it and technologies to measure it.
There is a definite need to cover all these aspects systematically and comprehensively in a manner that Industry personnel can readily relate to their processes.
Keeping this in view, Indian Machine Tool Manufacturers' Association (IMTMA) is organising a three hour online programme on “Surface Roughness Measurement and Validation”.
