Automatic cold edit control system of non-rigid shafts

Abstract

The article proposes a method for improving the quality of cold straightening of non-rigid shafts. The essence of the solution is to change the sequence of traditional technological operations by introducing dynamic straightening of the workpiece with subsequent application of a given depth of the deformed layer, immediately before roughing and finishing, and after them, in addition, in the process of roughing and finishing, the depth and nature of stresses are preserved. due to the exclusion and redistribution of surface stresses arising directly in the process of machining non-rigid parts, taking into account the changing dynamic characteristics of the cutting process itself. A complex functional diagram of the automatic control system has been developed. The results of straightening a non-rigid shaft, without a system and using automatic control, are presented. Decrease of processing error by 2..3 times is shown.
