NEW CLAMPING CONCEPT DEVELOPMENT AND ANALYSIS

Abstract

Clamping accessories are a necessary element of the tool-machine-workpiece machining system. When designing clamping accessories, in addition to its functionality, reliability, manufacturability, economy, and ease of handling should be respected. Classical clamping methods can restrict tool access during machining. This paper will present a new concept of clamping accessories with the possibility of clamping the workpiece using four clamping plugs. The idea is to drill four technological holes on the surface of the workpiece, which will later be used for contact between the workpiece and the clamping element. Clamping of the workpiece provides the rigidity of small parts, as well as the possibility of machining in 5 axes with one clamping of the part. In addition to the design of clamping accessories, the paper will also analyze potential problems. In order to support the theoretical model and conceptual solution, numerical analyzes were performed. The displacements of the clamping elements depending on the clamping force were analyzed in the FEMAP software.
