✦ Synopsis

Previously we put forward a thermomechanical model for the description of the process of chip formation. Now, this model is supplemented with the differential equation of the oscillating workpiece. The chip formation may provide an excitation within the machine-tool-workpiece system. Taking this interaction into consideration is expedient during the design of the machining technology, in order to avoid harmful vibrations. From this point of view, the chip formation can be considered as an oscillator. We analyse the expanded model and point out that the vibrations of the workpiece may lead to rather complex motions.

During the technical important combustion of SiCl 4 with calculations the thermodynamic data have been calculated first. On this basis it was possible to find the optimal oxygen [SiCl 4 (g) + O 2 (g) = SiO 2 (s) + 2•Cl 2 (g)] many intermediates have been detected in the past. However, the conditions
