Monofilar conical-helix antenna with low pitch angle

IEE Proceedings H Microwaves, Optics and Antennas, 1984
The radiation characteristics of a monofilar conical-helix antenna are investigated on the basis of the theoretical current distribution. It is shown that the current distribution may be divided into two regions, and that a decaying current from the feed point to a point of the first minimum is the major contributor to the radiation.

Helical Taper Reamers Milled With Constant Helix Angle

Journal of Fluids Engineering, 1945
Abstract The author explains the process of milling helical flutes on a taper reamer so that the flute will have a constant helix angle of 45 deg at every point along the length of the reamer. The problem is solved by the development of a former or master cam cylindrical in shape and bearing upon its lateral surface a helical groove such

The effect of helix angle on the life of slab-milling cutters

International Journal of Machine Tool Design and Research, 1967
Abstract Experimental evidence shows that the flank wear along the tooth of a helical milling cutter does not remain constant. The paper attempts (i) to relate the flank wear patterns to the variations in the undeformed chip section, using a concept termed the Integrated Reciprocal Modified Chip Equivalent, and (ii) to compare the magnitudes of wear ...
