Abstract

The roughness is the set of defects and irregularities of a micrographic and/or macrographic machined surface due to the machining of mechanical parts using machining tools. It is more difficult to obtain a low roughness index which necessarily increases the manufacturing cost. The objective of this experimental study is based on the analysis of the states of surfaces on different metals such as aluminium and bronze in order to measure and control the roughness obtained. A parametric choice is made to optimise several cutting parameters, namely the cutting tool, rotation speed, feed rate of the tool, and other parameters during turning machining without lubricants.

Keywords: • aluminium alloy • bronze alloy • metal turning • roughness • cutting parameters
