Abstract

In case of connecting the pieces that move comparing to each other, the exact calculation of envelope surfaces is an important question. By examining some cases, we can claim that exact knowledge about envelope surfaces play an important role in engineering design. Surfaces of space systems moving relatively that envelop each other mutually always touch on the characteristic curve. Along with their momentary touch, they can also cross each other in a cross line. In my investigations, I have found some cases which merit attention. In this paper some of them will be presented.
