Abrégé

The system performs control and virtual display (1) for a machine tool (M) which comprises a tool-holder (2) for a tool (T), a carrier (3) for a workpiece (W) to be machined by means of the tool (T), and a plurality of actuator devices (Al,..., AN) which can be controlled by means of associated drivers (D1,..., DN) in order to bring about controlled relative displacements between the tool (T) and the workpiece (W) along respective axes. The control system (1) comprises: a numerical controller (NC) which is connected to the drivers (D1,..., DN) and is suitable for implementing a machining program that is predetermined according to the features of the workpiece (W) to be produced and the features of the tool (T); the numerical controller (NC) is suitable for calculating, on the basis of the machining program, target coordinates defining positions of the tool (T) along the axes, which positions are to be reached by the activation of the associated actuator devices (Al, AN); image display means (ID); and a processing system (P) which is incorporated in and/or connected to the numerical controller (NC) in order to receive the calculated target coordinate values, and which is arranged to generate, on the basis of the target coordinates and of stored mathematical models of the machine (M), of the workpiece and of the tool, image data suitable for producing on the image display means (ID) a predictive, virtual, two-dimensional representation of the positions adopted by the workpiece (W) and by the tool (T) up to a preselected future moment.

Abrégé

Processes are provided herein for the preparation of acidic polysaccharide esters. One process comprises treating a quaternary ammonium salt of the polysaccharide with an esterifying agent, preferably in an aprotic solvent, and, if desired, salifying free carboxy groups in the partial esters obtained, or releasing salified groups in them.
