Abstract

Recently, significant technological progress has been accomplished in the field of cutting processes, which still lasts nowadays. Namely, the processes requiring a significant amount of coolant are have been replaced by new processes requiring no coolant or demand minimal cooling. A typical example of this replacement is the change from grinding for hard turning. In the framework of the present research work, hardened bores of gears were machined by either wet grinding or dry turning. In order to compare the results, 3D roughness investigations were done on ground and hard-turned surfaces. It has been stated that 3D parameters provide more detailed and richer information than the 2D parameters that have been used for a long time. The aim of the investigation of these parameters is to prove that hard turning can securely guarantee the prescribed roughness parameters and does not present any disadvantage compared to grinding. However, besides this, more typical properties were observed on the turned texture, which significantly differ from grinding. The difference is reflected by the areal material ratio curve.
