Question:
You are a Manufacturing Engineer in an aerospace company, and you are working on a task to
perform an end milling operation on Titanium Ti−6A1−4V workpiece. You are aware that
Titanium alloys are considered as "difficult−to−cut" materials, but you would like to study the
possibility of performing the operation at higher cutting speeds while enhancing tool life.
You need to report the results of this task to your director, and you are requested to cover the
following main elements in your summary report:
1. Identify the type of cutting tool that could be used for end milling of Ti−6Al−4V.
2. Provide a list of available cutting tool materials that could be used for Ti−6Al−4V.
3. Possible tool wear mechanisms associated with Ti−6Al−4V machining.
4. What are the available tool coatings that could increase the tool life and make it possible
to perform this operation at higher cutting speeds?
5. Would you consider high−speed machining in this application? And why?
6. Select the proper cutting tool for end milling of Ti−6Al−4V. Your recommendation
should include: one tool material, one tool coating (or uncoated tool), speed range for this
cutting operation, and dry or wet machining condition
