Take apart a few old DVD drives, stitch them together with cable ties, add a pen and paper, and you’ve got a simple CNC plotter. They’re quick and easy projects that are fun, but they do tend to be a ...

Learn how to convert points between rectangular and polar. Rectangular points measure the horizontal and vertical distance ...

There are some times when a picture, or better yet a video, really is worth a thousand words, and [heinz]’s dual-disk polar 3D printer is one of those projects. Perhaps the best way to describe it is ...

"Coordinates for the CNC Lathe" provides an overview of the coordinates used to program cutting operations on CNC lathes or turning centers. It introduces the systems of both Cartesian and polar ...

Learn how to convert points between rectangular and polar. Rectangular points measure the horizontal and vertical distance ...

This application note presents space vector control or field-oriented control (FOC) using polar coordinates. It is used for controlling 3-phase alternating current induction motors (ACIM). The ...

Particle P travels on an elliptical path, as shown above. The equation for an ellipse in polar form is provided above, with the origin of the polar coordinates at point O. The animation below shows ...
