The problem of clamping complex or low-stiffness parts in technically and economically advantageous conditions is of interest for many manufacturing companies. An emerging method for this type of parts is fixing with adhesive. This paper proposes a new adhesive fixing method for low-rigidity parts, using adhesive tape. The use of adhesive tape minimizes the vibrations induced by the tool in the workpiece and minimizes chatter. This method, although simple and cheap, has not been considered before. The validation of this fixing method was done after a series of tests to determine the holding capacity and stability of the fixed part during the machining process. Therefore, a fixture was designed and manufactured to determine the tensile and shear load capacity of adhesive tapes. Two types of parts from different materials and shapes were machined to determine the stability of the fixed part during machining. After determining the dimensional, shape, and positional accuracy, the method was found to be valid. The method has a high potential for clamping parts with low rigidity for machining.
