Adaptive drive of the technological machine with two working movements of the executive body

Abstract

The article deals with the machines schemes, having an executive body making two movements and establishing a relationship between them. The ratio of the moving velocities, or the ratio of the two displacements of these movements, or the ratio of the applied powers to each of these movements, determines the indices of the working process, and often has an optimal value. A typical example of this type of machine is a drilling machine. The ratio of rotation speed and the feed rate determines both the specific power intensity of the cutting process , the intensity of the wear out and drilling capacity. The structural schemes of the drive of some other technological machines are considered. On the example of a device used for processing curved surfaces in metalworking, a process of automatically adjusting chip thickness with a hydraulic drive having an adaptive structure is described. The efficiency of self-regulation is shown by means of using relatively simple circuit solutions.
