Description du projet/ Project
Description
Chemical milling is used for creating
shallow pockets in thin panels. Mechanical
milling is sought as a replacement
process due to its lighter environmental
impact. Many unknowns remain before
mechanical milling can be effectively
used. What are the necessary conditions
for the process to be possible? Cutting
parameters, part-fixturing-machine
rigidity and damping, accuracy and
flexibility of the part, are all
unknowns.
Objectifs/ Objectives
- Determine machining conditions
allowing the machining of pockets in
thin panels, considering cutting
conditions, tool path, tool geometry,
tool coating, fixturing dynamics (stiffness,
damping and inertia), near surface
microstructure distortion, residual
stress, surface finish;
- Determine machining conditions
allowing a reduction of residual stress
within design limits;
- Investigate the use of an
industrial robot to carry the machining
head;
- Validate a new concept in panel
machining to hold the panels and allow
machining within the required tolerances;
