Challenges in Machining of Silica–Silica Cone for Aerospace Application
Silica–silica composites are generally used in high-end aerospace applications. They are highly temperature resistant, have low thermal conductivity and low density, and are abrasive in nature. Additionally, due to the soft and brittle nature of the material, it poses challenges during the machining and clamping of the workpiece for achieving the required shape and size. In realizing quality hardware, it becomes very critical to suitably plan the machining strategy. A manufacturing methodology is established to carry out machining of silica-based composite with primary focus on the development of special turning fixtures as a shop setup. This paper discusses the criticalities involved in the machining of the silica material using suitably developed fixtures.
