Program Purpose:

Machining is a critical part of manufacturing airframe parts, but productivity of these processes is limited byx000D
the high flexibility of the workpiece, which may cause vibrations, dynamic deflections, and chatter and lead tox000D
poor surface finish and damage to the workpiece or the machine tool. This project aims to minimize thex000D
machining time of some thin-walled aluminum airframe components without causing chatter or violating thex000D
surface finish and dimensional tolerances.x000D
x000D
UVic's Advanced Manufacturing (UVICAM) laboratory will adapt tool selection, spindle speed selection,x000D
feedrate scheduling, and toolpath planning strategies as well as High Speed Machining technology for thex000D
milling process of three airframe parts that are being produced at Viking Air's North Saanich plant. Chatter freex000D
parameters will be identified by implementing the newly developed Finite Strip Modeling method, and byx000D
conducting impact hammer tests on the workpiece. The objective is to enhance the developed modelingx000D
approach to solve important industrial problems, also to verify the efficiency of this novel technology inx000D
increasing the productivity of Canadian manufacturing industry.
