“…Ignoring the importance of certain properties of the hob milling tool materials is one of the main reasons for the lack of understanding of the main functions of the layer's stability on the hob milling tool. There are more than one hundred different methods of surface coating of metals and alloys, by which it is possible to increase the efficiency of the tool to a certain extent [16][17][18][19][20][21][22]. An overview of basic techniques and surface engineering (surface modification and application of a layer) is shown in Fig.…”

“…The gear is an element of a large number of tribo-mechanical systems. The geometrical parameters of the hob milling, the accuracy of the profiling and the accuracy of manufacture significantly affect the productivity and machining costs [2,3,7,22,23,27]. In this paper, wear and roughness of the real hob milling tool, the topography and roughness parameters of lateral flank and tooth-face of the model hob milling tools are analyzed before and after gear cutting of cylindrical gears.…”

Hob milling process is one of the most important links in the chain of machining because productivity, final geometrical accuracy and gear cutting are very dependent on it. The quality of the machining of gear serration is one of the conditions for achieving the required quality of the work-piece. In this paper the methodology for the identification of topography of tool teeth and gear serration produced by uncoated and coated model and real hob milling tool is presented. 6MATEC Web of Conferences 287, 05003 (2019)

In the manufacturing industry, tool wear prediction is critical for increased productivity and product quality. The focus of this study is to compare the results obtained via an artificial neural network (ANN) models for tool wear prediction on machining a nickel based super alloy: Nimonic C-263 alloy with other prediction method and the effects different parameters have on the efficiency of prediction. In this study, flank wear area (in micron2) is used as the wear indication variable during machining since it influences the precision, stability, and reliability of the machine, whereas cutting speed, feed, and depth of cut are used as input factors. Other variables include cutting force, temperature and MRR. The experimentally determined values will be utilised to train an artificial neural network (ANN) for tool wear prediction. To minimise extraneous variables, correlations between the parameters and wear are determined. The ANN model's error of forecasted response values is compared to other models such as linear regression, as well as prediction values without the elimination of variables. A GUI will also be created that lets the user input the necessary parameters to trained neural network model which then predicts the flank wear area. Results indicate that eliminating parameters resulted in reduction of prediction error (from 11–8%) and also it was found that ANN produced better results than linear regression, decision tree and random forest. Hence, more precise estimation of tool wear can be performed in a lesser time-frame. Number of experimental trials had to be limited due to unfavourable circumstances. The dataset size had been increased by assuming linearity between two results. However, this is justified as the objective is to compare prediction accuracies before and after elimination of variables after a correlation study.

Abstract. The improvement of the gear cutting process by hob milling is also significant for the producers of gears as well as for the producers of hob milling tools. Due to the complexity of the process, the high values of the gears, and in particular the hob milling tool, the research of the bases for optimizing the process of gear cutting by hob milling requires significant financial resources and significant efforts of the researchers. In the modern production of gears there is a continuous demand for increasing the economy. In the gear cutting process improvements of the production equipment and materials for the cutting elements of the hob milling tools are necessary. In this paper an analysis of the tool life of coated hob milling tools for gear cutting of cylindrical gears is given. The experimental results have shown that the hob milling tools with inserted combs coated with TiAlN outperform the hob milling tools with inserted combs coated with TiN. They have higher resistance of 60.6 %.
