A Parametric Model for the Straightness Deviation in the Cutting Processes of Aluminum Alloys

Abstract

Light alloys are increasingly applied in different industrial sectors, mainly aerospace. Because of this, it is needed to analyze their behavior in the different processing procedures and, specially, machining. On the other hand, up to a few years, cutting fluids were successfully employed in these processes since their coolant and lubricant properties. Notwithstanding, environmental necessities have promoted researches focused on the development of cleaner processes avoiding cutting fluids, in particular, dry machining. However, this process can change tool geometry and affect to the material giving rise to changes in the design specifications. In this work, geometrical deviations, particularly straightness deviations, in the dry turning of UNS A92024 (Al-Cu) alloy are studied as a function of feed and cutting speed through a parametric model.

A Study of Macrogeometrical Deviations in the Dry Turning of UNS R56400 Ti Alloy

“…Comparing the differences with the analysis of SD(v) the changes are indicative of a steeper slope. Similar considerations have been found in previous works for aluminium alloys [8]. A similar evolution was found in a previous study on the influence of the cutting parameters on the microgeometrical deviations of dry turned Ti based alloys workpieces [4,9].…”

Cutting Speed-Feed Based Parametric Model for Macro-Geometrical Deviations in the Dry Turning of UNS A92024 Al-Cu Alloys

“…Notwithstanding, the most studies that can be found in Literature are commonly focused on the analysis of dimensional parameters, mainly roughness parameters, such as Ra or Rz [2]. So, there is a lack of research works about the study of the surface quality under the point of view of geometrical deviation parameters [3,4].…”
