Tool Angle in Bevel Gear Cutting

 

Starting Point:

For cutting processes, efficiency is generally determined by tool wear and the tool life. By means of special machines that possess complex machine and process kinematics the desired bevel gears can be manufactured. The tool wear varies locally along the profile edge and is determined especially by the process design regarding the technological tool angles and the feed strategy. Determining the parameters is usually based on empiricism and poses a challenge, as non optimal process design lead directly to unplanned interruptions of production, such as necessary tool changes. Simulation models for bevel gear manufacturing increasingly gain in importance and offer a significant saving potential by means of a purposeful process design. However, an exclusively simulative prediction of tool wear is not yet possible

Research Objective:

The objective of this research project is a guideline for designing the technological angles of the tool for the industrially wide spread process of face milling. The focus lies especially on a robust definition of the tool geometry and for this reason different combination of tool angles are investigated for several cutting parameters. The scientific objective is an extensive and initial methodical investigation of the technological tool angles and feed strategies for bevel gear cutting and their influence on tool wear. Especially observing and analyzing the relation between different feed strategies and the technological tool angles helps expanding the scientific basis for bevel gear cutting.
