Evaluation of Selected Parameters of Structural Quality Steel Turning

An important role in achieving the desired surface quality parts is crucial material parameter of assessment ratio profile. This parameter tells us whether it is possible to use a specific surface finish appropriate code for the component parts of machinery (eg in the automotive industry, crankshaft, etc..). For machining tool was used with a precisely defined edge, there was a process of turning. This article deals with the assessment of surface quality, it is a material parameter of interest (so-called Abbott curve), commonly evaluated parameter is everywhere roughness Ra. The median arithmetic deviation (Arithmetical mean deviation) Ra surface is commonly used in engineering drawings as prescribed surface quality, but the state machine components do not tell us anything.
