Surface roughness is the totality of microgeometric irregularities on the surface of an object and it is caused by various factors, from which the most important are machining and processing techniques. This characteristic of the material is very important, especially in the case of high-quality materials designed for the demanding conditions of exploitation. In this work the tests of surface roughness Nimonic 80A were carried out. The tests were performed after the different tehnological phases during processing of Nimonic 80A using Sutronic 10 instrument. This instrument work on the principle of ultrasound which measures the aritmetic value of Ra, i.e. parameter for determining the surface roughness.
