Ultra-precision grinding of hemisphere couples on TiC-based cermet was conducted in the present work to achieve optical quality surface. Wheel normal grinding was utilized to avoid the interference between the machined surface and diamond wheel. Sharp grinding edge of the wheel was firstly prepared with a green silicon carbide (GC) stick as truer. The results showed that surface finish …

|In this Chapter Dr. Townsend tells us the story of the beginnings of the Townsend Plan, and he reproduces the famous Letter to the Editor of the Long-Beach Press-Telegram, which started the whole thing.)|As I look back upon it, I can see that the Townsend Plan was not born all in a lump, but took gradual shape. Certainly it has undergone evolutionary revision since it first saw the light of ...

Abstract : A new contact type on-machine measuring system is developed in order to measure aspherical optical parts with steep surface angle for high numerical aperture (NA). A ceramic air slider made of SIALON is adopted for the measurment probe because of its low thermal expansion coefficient, high rigidity and light weight.
