(a)
An engineer would like to drill a square hole of 20 mm x 20 mm with depth of
25 mm on a layered structure of natural fibre-reinforced polymer composite. He
encountered delamination problem in the workpiece (Figure 3) when he used
conventional cutting tool to drill the hole. Instead of using conventional
machining process, discuss ONE suitable advanced machining process that can
be applied for this machining purpose and predict TWO possible limitations for
the selected process.
Cutting
Tool
Delamination
Composite Material
Figure 3. Delamination of the composite material.
Please explain steps in detail.
Figure 9 shows the effect of rotary speed on the material removal rate by using conventional EDM and ultrasonic-assisted EDM.
Discuss on the effect of rotary speed on the material removal rate for both EDM processes.
