Abstract

In this work a new method for online identification of the relation between the dimensional deviation and the cutting force, with the object of building a mathematical model to be used for online compensation of the dimensional error. The key idea is to identify this relation separately for each one of the two generating curves (the generatrix and the directrix) using the SVM regression technique. The resulting mathematical model can be used in order to predict the values for the dimensional deviation based on the current position of the tool and on the measured values of the cutting force. The identification method was tested for an entire batch of turned workpieces. The results showed that by using the proposed method the machining error can be reduced by 2,5 times.
