Partially Regular Microreliefs Formed by Rotation

Abstract

A new scheme for forming partially regular microreliefs by rotational rolling is proposed. A new transcendental curve-shaped, partially regular microrelief (of a trochoid type) is discussed; the shape and geometric parameters of its grooves are substantiated. Grooves discussed below proved to be technologically advanced, providing for a high performance of all types of equipment. Once combined, they act together to provide for the best in-service properties of planar, partially regular microreliefs formed by rotation, which are unparalleled among those of their kind. Analytical dependences are presented that describe the groove’s shape. A relationship is established between the main technological parameters, that is, feed rate and rotation frequency of the deforming element that produces microrelief grooves of different shapes and sizes. Possible location variants for microrelief grooves are given and classified. Technological layouts and movement cyclograms are substantiated for the tool that forms regular microrelief grooves by means of rotation. A comparative analysis of the profile lengths of the grooves of rotational and sinusoidal microreliefs modeled in the MathCAD environment was conducted.
