Abstract

The article describes the basics of the technology and metrology of variable-pitch cone worms that are used in plastic extruding presses. Two worms operate in the plasticizing system of an extruder. It is assumed that the axial profile of a worm should be rectilinear, and the clearance between the threads of mating worms in the axial section should be constant along the worm length and the thread height. The article focuses on the technology and measurements of worms and considers the potential for the development of this technology.
