Much research has gone into machining process monitoring and control. This paper reviews monitoring and control schemes of cutting force and torque. Sensors to measure cutting force and torque, as well as their indirect estimation, are reviewed. Feedback control schemes and model-based feedforward scheduling schemes of cutting forces, as well as tool path optimization schemes for cutting force ...

We define spinc prequantization of a symplectic manifold to be a spinc structure and a connection which are compatible with the symplectic form. We describe the cutting of an S-equivariant spinc prequantization. The cutting process involves a choice of a spinc prequantization for the complex plane. We prove that the cutting is possible if and only if the moment map level set along which the cut...

In order to produce components in optical quality in ultra-precision cutting processes it is very important to have a highly balanced system. Achieving the best possible balancing state is a time consuming process. Therefore, the prediction of the influence of the balancing state on the surface quality of the component is desirable. On the other hand, such a model should enable us to predict a ...

The manufacture of parts made of metal sheet often includes two successive processes: the cutting process at which a guillotine shear cuts the sheet into strips, and the punching process at which a stamping press punches out the blanks from the strips. This paper presents an algorithm for generating optimal two-staged cutting patterns of strips for the cutting process. At the first stage the sh...

Chatter suppression is essential for achieving high precision and surface quality in machining processes. In this paper, a control strategy is presented for chatter suppression in cutting process in the presence of tool wear and parameter uncertainties. A single-degree-of-freedom model of a turning process in the orthogonal cutting configuration is used to set up the nonlinear delay differentia...
