Περίληψη

The key components in demanding transmission chains are doubtlessly premium well designed and properly fabricated gears. The desired gear quality is performed, through three manufacturing stages, i.e. the rough cutting, the heat treatment and the finishing process. One of the most adopted methods in gear finishing is a variation of hobbing, the so-called gear skiving or hard hobbing. As every cutting process based on the rolling principle, gear skiving is an exceptional multiparametric and complicated method, which can and must be fully optimized. This paper illustrates an involved algorithm that simulates rigorously the skiving process and yields data, such as the dimensions of the non-deformed chips and consequently the cutting force components. This algorithm is supported by a computer code that offers the aforementioned parameters, with the aid of a user-friendly graphical interface, built modular and object oriented. Bearing in mind that gear skiving is a finishing gear cutting process, the developed software initially performs the simulation of the gear cutting, in order to determine the cutting boundary conditions. The aim of this research work is to interpret quantitatively cutting phenomena related to the course of the cutting force components and is extendable to predict the wear progress of complex and expensive cutting tools. In this way, the optimization of the cutting process is enabled.
