PT Journal AU Hricova, J TI Influence of Cutting Tool Material on the Surface Roughness of AlMgSi Aluminium Alloy SO Manufacturing Technology Journal PY 2013 BP 324 EP 329 VL 13 IS 3 DI 10.21062/ujep/x.2013/a/1213-2489/MT/13/3/324 DE aluminium alloy; cutting tool material; milling; surface roughness AB Milling is one of the most universal operations in machining processes because it can remove the redundant part of material efficiently, and moreover, it can produce almost all kinds of contour surfaces with a high quality finish. Surface roughness plays an important role in determining the product quality since it strongly influences the performance of mechanical parts as well as production cost. Many types of cutting materials are used as tool materials in today's metalworking industry. Selecting the proper cutting tool material for a specific machining application can provide substantial advantages including increased productivity, improved quality and ultimately reduced costs. This article is aimed at determining the influence of different tool materials on surface roughness of AlMgSi aluminium alloy after side milling with using of the analysis of variance (ANOVA). ER
