Two axes of motion are used by a conventional single point diamond turning (SPDT) lathe to describe a curve in space. The curve is formed between the centerline of the work piece to be machined and ...

Unless you’re in a carnival funhouse, mirrors are generally dead flat and kind of boring. Throw in some curves and things get interesting, especially when you can control the curve with a touch of ...

Sketch the graph of the ellipse \(\ds \frac{x^2}{9}+\frac{y^2}{16}=1\) and determine its foci. Let \(C\) be the conic which consists of all points \(P=(x,y)\) such ...

The circular shape of constant-energy contours (mapped in reciprocal space) correspond to conic sections of a Dirac-cone. Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news ...

The advent of four axis SPDT enables the generation of non-axisymmetric surfaces. This tool has two extra motions in addition to the orthogonal two axes of motion (x and z axes) featured in a SPDT ...
