Description du projet/ Project
Description
The milling, drilling and routing
optimization of graphite/epoxy composite
and multilayer materials is addressed in
this project. Optimal parameters (speed,
feed and depth) and tooling (materials,
geometry and coating) will be determined
for specific machining operations to
ensure quality of the machined parts (dimensional,
geometrical, surface finish and
mechanical properties integrity), tool
life and effective machining costs. The
5 axis machining of graphite/epoxy is
also addressed with the same expected
outcomes.
This project will investigate current
practices in graphite/epoxy and
multilayer material Al-Li/Ti/composite
drilling, trimming and 5 axis milling,
and propose proper cutter geometries and
materials as well as optimal machining
parameters related to these tools with
respect to quality, productivity and
cost. Orbital milling (drilling) will
also be investigated to propose
recommendations regarding its further
utilization from the industrial partners.
The fixturing aspect, which is a major
concern considering the small
thicknesses of the parts and the
machining forces involved need also to
be investigated.
Objectifs/ Objectives
A. Develop analysis tools for the
efficient machining of graphite/epoxy
composites and multilayer materials;
B. Develop models for predicting the
delaminating with respect to the
cutting forces for the drilling and
trimming processes of one composite and
one multilayer material based on cutter
geometry and machining parameters;
C. Predict cutting tool life for the
drilling and trimming processes
according to specific tools and
machining conditions;
D. Develop analysis tools to assist in
the 5 axis tool path generation for
surface machining to attain, in mean
term for the industry, a global
objective of a shimming free assembly of
components;
E. Explore the orbital drilling process
and part fixturing methods and determine
usefulnessand industrial potential.
