“…The work presented above emphasizes more on the chip geometry, whereas the work of other researchers is more focused on the 3D gap. In their research, Michalski and Skoczylas used a CAD environment to model the flanks of hobbed gears [13]. Focusing on the realistic and accurate simulation of the gear hobbing process, a 3D approach for the simulation of manufacturing spur and helical gears is presented in this research paper.…”

Cear hobbing is a common method of manufacturing high precision involute gears. The thorough knowledge of the developed cutting forces and the wear of the cutting tool are of great importance in order to produce helical and spur gears as they infiuence the cost of the manufacturing process and the quality of the produced gear. A novel simulation code called H0B3D was created in accordance with the above. This code can simulate the complex movements involved in gear hobbing with the best available accuracy, which is achieved by embedding the developed algorithm in a commercial computer aided design (CAD) environment. The simulation code calculates and exports the total cutting forces as well as the cutting forces in every cutting edge involved in the cutting process.

“…Pohit [11] developed solid models for the cutter and tooth blank and finally simulated gear-manufacturing processes for spur and helical gears. Michalski and Skoczylas [12] suggested a computer simulation method for modelling tooth flanks of cylindrical gears. The surface topography of hobbed tooth flanks is compared to their numerical models.…”

A new model of the gear hobbing process is presented in this paper to determine the micro tooth surface topography in spur and helical gears. The model is based on the generation of tooth surfaces by successive cuts of the finite number of hob teeth, as they come into interaction with the gear tooth. For every relative position of the hob and the gear, an analysis is carried out to find the active cutting edge points which generate the gear tooth surface. Repeating this procedure for all the selected gear tooth surface points, the micro topography of the gear tooth surface is determined. Therefore, the developed method determines the deviations of the manufactured tooth surface from the theoretical tooth surface of spur and helical gears. The method is applied to improve the micro tooth surface topography of spur and helical gears, namely to reduce the deviations of the hobbed tooth surface. Spur and helical gear examples are used to demonstrate the effectiveness of the method.

“…Later, additions have been made in this model including cutting forces and wear calculation (Bouzakis and König, 1981;Bouzakis, 1980;Gutmann, 1988;Joppa, 1977). Another simulation code introduced by Michalski (Michalski, 2009;Michalski and Skoczylas, 2008a;Michalski and Skoczylas, 2008b) used a CAD environment in order to produce the geometry of flanks which were machined by means of gear hobbing. A mathematical modeling of the process, where chip characteristics as well as the flank geometry are calculated, was also presented by Vedmar (Vedmar, 2010;Vedmar, Andersson and Stahl, 2009).…”

In every manufacturing process the prior knowledge of the developed cutting forces is crucial in order to increase the cutting performance and make the optimal selection of cutting conditions. In gear hobbing the complexity of the process as well as the diversity of the produced chips makes it difficult to create and use empirical charts that predict cutting forces according to the process parameters. The simulation model Hob3D was developed in an effort to create an accurate model for gear hobbing that can produce reliable results for the cutting forces. The effect of the various parameters of the gear hobbing on the developed cutting forces by the aid of Hob3D is presented in this paper.
