This article deals with the problem of rational turning mode assignment for thin-walled

workpieces. In this instance, the deformations of the workpiece, caused by cutting and

clamping forces, strongly affect the accuracy of the result. Deformed workpiece pro-

cessing leads to significant

deviations from a predetermined size. Traditional thin-walled

parts processing methods (using machining attachments) are inappropriate in some cas-

es. For example, it is not profitable to use special machining attachments for small batch

processing. So, the method of rational turning mode assignment is proposed as an alter-

native. One can assign the rational turning mode based on accounting rigidity of work-

piece. This “soft” mode is required to provide small processing deformations. CAE mod-

eling method is appropriate to resolve the parameters of rational mode. Depending on

modeling results, one can choose apply either traditional method or process the work-

piece with standard machining attachments (e.g. three-jaw chuck). To use the method on

practice, it is required to reduce its applicability. To this end the software system was de-

veloped. This paper considers technical aspects of implementing the system and related

problems resolution.
