Ultraprecision diamond machining enables physical realization of freeform surfaces of nearly arbitrary complexity through turning and milling processes. Achievable form accuracies make diamond machining a viable alternative to conventional techniq...
The effect of a variable rake machining process such as Fast Tool Servo (FTS) on optical IR crystalline materials isn’t well understood and can be difficult to test. This thesis proposes and develops the concept of using a 'starburst' cut geometry...
The mechanical and thermal properties offered by Silicon carbide (SiC) make it an ideal material for reflective freeform optics. However, the hardness, brittleness and fracture toughness of the material pose a challenge to manufacturing. The manuf...
