Universal-composite adjustable machine-tool attachments

Abstract

The basic requirements on positioning attachments in numerically controlled metal-cutting machine tools are considered. Existing adjustable, composite, and special attachments are analyzed. A new system of universal-composite adjustable attachments is proposed. The structure and characteristics of its components are outlined. As an example, an automatically adjustable universal attachment is developed for the machining of stepped shafts on numerically controlled milling and boring machines.
