TUNING OF AN EXPERIMENTAL DEVICE FOR MEASUREMENT OF DYNAMIC COMPLEX FORCES WHEN TURNING

摘要

This paper reports on the tuning of dynamic properties of an experimental device used for identification of complex cutting forces that form a new force model, which should ensure a higher accuracy of the stability prediction. The dynamic properties of the device had to be tuned because of the natural frequency present in the working range. An investigation of the appropriate thickness and composition of plate springs and damping interlayers as well as the type of contact grip of the plate springs is the main task of the paper.
