Machining mechanism
Composites: • brittle fracture
The bres are shattered and cut•
- The force needed is much lower
- The tool toughness can be lower
- Coolant or lubricant are often not necessary
On the other hand, bre • hardness is extremely high
- Highly abrasive
Resins are weak•
- Interlayer fracture → delamination
- Elastic mismatch → irregular surface
- Easy pull-out of bres → enhanced splintering
