Abstract

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.

Highlights

It is well known that the structure and individual components of modern industrial complexes represent superior range and the most complex products in the respective fields of science
The greatest technological achievements of various industrial branches are merged at the constructors of modern industrial complexes and they are integrated into their products
Taking into account the results of the six most commonly used parameters of the roughness of the input lateral flank of the model hob milling tools from the first part of the experimental research in which the roughness of the same tools were compared in the unworn and worn-out state, it can be concluded that the maximum values of the roughness parameters most often occur on the first direction of measurement in the case of wornout tool, and the minimum values in the fifth direction of measurement in the case of unworn tool, which indicates that the worst change of the surface topography is in the worn-out zone near the cutting edge, with the note that the results of each parameter vary widely

Summary

Introduction

It is well known that the structure and individual components of modern industrial complexes represent superior range and the most complex products in the respective fields of science. Point of view of the machined surface quality and from the point of view of productivity. A prerequisite for the successful optimization and adequate process control is its identification, respectively identification of occurrences originated during hob milling. The thin layer beneath the working surface has the deformed crystal structure. The rapid development of industrial production in the world has caused the need for extensive research in all fields, even in the field of machining. The development of technology of hob milling is successfully used in roughing as well as fine machining of serration. The demand for process optimization has been grown up, both from the
