PT Journal AU Mital, D Hatala, M Bernat, A Czan, A Vybostek, J Ungreanu, N TI Dependence of Surface Roughness on Depth of Cut for Aluminum Alloy AlCu4Mg1 SO Manufacturing Technology Journal PY 2018 BP 285 EP 288 VL 18 IS 2 DI 10.21062/ujep/92.2018/a/1213-2489/MT/18/2/285 DE Lathe; Roughness; Surface Quality; Cutting Plates AB Presented article is focused on evaluating surface quality parameters Rz and Ra after turning made by various cutting conditions. Monitored parameters in experimental part were feed rate, cutting speed and depth of cut. Researching optimal cutting conditions, which sets often affect and increase productivity, quality and precision of manufactured products. Aim of the article is to increase quality of current state, what require long time testing and experiences. Article also presents individual comparing of two selected cutting plates in various cutting conditions, when in conclusion are clearly define results of experiment and requirement for practical using in industry.
