30 hp – Statistical analysis of vibrations in gear machining operations
 

Introduction
We are looking for students who want to work with the latest production methods and, at the same time, help to create a more sustainable world. At Scania we call this Driving the Shift. This means that we take a leading role in developing climate-smart solutions by creating sustainable, environmentally friendly products.

Thesis project at Scania is an excellent way of making contacts for your future working life. Many of our current employees started their career with a thesis project.

Background
Cutting vibrations offer valuable insights into tool health and machining conditions. By studying these vibrations, we can detect tool wear and breakage before they lead to defects. Furthermore, optimizing cutting parameters based on vibration data can enhance machining performance.

Objective

The objective of this thesis is to perform a statistical analysis of vibrations in gear machining operations to identify key indicators of tool wear, breakage, and geometry deviations. Additionally, the study aims to use vibration data to optimize machining operations by adjusting cutting parameters, thereby enhancing process efficiency and product quality even for new materials.

Job description

Your task will be to review existing literature on the relationship between cutting vibrations and tool wear, breakage, and geometry deviations in machining operations. In the next step, you will collect and analyse vibration data from real gear machining processes. This analysis will focus on identifying statistical patterns that can serve as early indicators of tool health issues. Following the data analysis, you will work on developing a model to optimize cutting parameters—such as speed and feed rate—based on the vibration data.

The output of this thesis would be:

• Statistical Indicators for Problem Detection
• Guidelines for Data Collection and Interpretation

Education/program/focus
