Why is SiC challenging?
SiC is very hard and brittle. Cutting must control force, heat, micro-cracks, edge damage, and wire wear.
How do speed and feed affect SiC sawing force?
Research themes show that feed rate tends to increase force, while suitable increases in wire speed can reduce force within a stable range.
What should a SiC test record?
Record force if available, cut time, edge quality, kerf, surface condition, wire wear, cracks, and whether polishing allowance is acceptable.
