Hybrid technologies offer an important approach to enhance existing limits of conventional cutting manufacturing processes. Superposition of the infeed with adapted ultrasonic vibrations enables reductions of machining forces. This results in diminis

Today in the production of internal combustion engines it is possible to make pistons as well as cylinders, for all practical purposes, perfectly round. The negative consequences of the subsequent assembly processes and operation of the engine is tha

Tool making is a very time consuming and expensive operation because many iteration loops are used to manually adjust tool components during the try‐out process. That means that trying out deep drawing tools is 30% of the total costs. This is the r

As known, the electrical induced strain of conventional piezoceramic materials is limited by 0.12 % (2 kV/mm), which often requires strain transformation designs, like levers, in order to meet application needs. High fabrication accuracy and low tole

This paper presents a mechatronic strategy for active reduction of vibrations on machine tool struts or car shafts. The active structure is built from a carbon fiber composite with embedded piezofiber actuators that are composed of piezopatches based

The most important project in sheet metal forming is streamlining the material flow since each rejects increases production costs. Using the multipoint cushion device together with an elastic blankholder makes it possible to actively manipulate the m
