Résumé

The manufacturing of aeronautical components requires accuracy, repeatability and efficiency. Nevertheless, for today industry, machining processes should not only be effective in terms of technical requirements and economic issues, but also they should be sustainable in terms of environments and operator’s safety. It is well known that the use of cutting fluids during machining is costly and can be hazardous for the operator. However, the dry machining induces excessive friction on the tool/workpiece and chip/cutting tool interfaces leading to increased emission of fine particles and nanoparticles which deteriorate the workshop air quality, can constitute a real risk to the health of operators and shorten the reliability of the machine-tools components. Knowing the conditions leading to reduced metallic particle emission could help improving the occupational safety of the machining processes. This paper presents experimental and theoretical investigations on particle emission phenomenon during dry machining of aluminum alloys (7075-T6 and 6061-T6) used in aeronautic applications. The main goal is to predict the particle emission as a function of machining conditions in order to determine safe and economic machining process windows.
