Vibration in machining of thin walled aerospace components, (phase II)

Reference number
Coordinator Volvo Aero Aktiebolag
Funding from Vinnova SEK 1 600 000
Project duration July 2009 - June 2011
Status Completed

Purpose and goal

The project aims to investigate the process method of turning-milling in combination with using a cell fiber ceramic as tool material. While machining at high speeds and feeds the specific cutting force is reduced significantly. This decreases the power that causes the forced vibrations. The goal is to create a process window where the ceramic cutting materials can be used without vibration in the machining of thin-walled aerospace components.

Expected results and effects

The project´s ultimate goal is in two parts. Create process windows oIdentify and rank the factors that discourage the use of ceramic milling tool for machining of thin-walled parts. oSensitivity analysis of these factors oProposal for tool selection and cutting parameters Develop a first mathematical model for managing vibration generation in the milling of thin-walled parts.

Planned approach and implementation

The project is planned to be implemented in the form of 4 work packages described below: WP1 (Q3-Q4 2009): Perform turn milling entry attempts on a thin-walled Aerospace component. Where the cutting forces and acoustic pressure is measured WP2 (Q1-Q2 2010): Perform tests with the new cell fiber cut, but reduced friction. Develop simulation model for prediction of sound pressure. WP3 (Q3-Q4 2010): Parameter Study on damping aids on the fixture to reduce the sound pressure. WP4 (Q1-Q3 2011): Building dampers with plasma from a nano-composite material. And perform experiments and verified the validation of simulation model. Volvo Aero´s operations in this project consist of: to provide expertise in production and processing of aircraft engine components. to provide specimens for testing with turn- milling. lead project meetings University West efforts in this project consist of: to provide expertise in cutting technology be research Performers to participate in projects and steering committee meetings
