Open-cell silicon foam which is difficult to cut due to its low stiffness was successfully machined by applying liquid nitrogen for freezing the material.
Constant Thrust Force Grooving of Glass
Grooving of glass could be stably conducted with constant depth by controlling the thrust force.
Electrochemical Discharge Assisted Cutting of Chemically Strengthened Glass
Reverse ion etching (K+ => Na+) and stress relaxation at the surface of chemically strengthened glass could be made by applying electrochemical discharge, which allowed for cutting of the glass by mechanical scribing.
