Study of the roughness of carbon fiber-reinforced composite plates in peripheral cryogenic milling

摘要: In recent years, the cryogenic machining is being studied with interest due to its potential as an environmentally friendly process and possible efficiency. Some improvements in final parts have been achieved this respect conventional machining, can be surface quality some alloys. This paper presents a study focused on peripheral milling of composites reinforced carbon fiber, particular roughness, which compared results obtained milling. The methodology used combines experimentalism statistics. tests were carried out center at different cutting conditions (cutting speed between 4000 8000 rpm feed rate 0.25 0.75 mm/rev); fluid, liquid nitrogen, impacted directly tool, did not affect composite plates. experimental outcomes, measured by profilometer, statistically analyzed most influential parameters variables identified, confirming good performance contributing greater knowledge process.In variabl...
