The invention relates to an artificial block of the type formed of a revolution part organised about a vertical axis forming a core.

The invention concerns a method for making a part with clearance volume by rotational moulding, or by a technique for depositing successive layers, and a part obtained by said method.

The ability to work on parts of different geometries: from revolution elements until prismatic elements.

The potter’s dexterity allows her to free herself from the wheel to produce an almost perfect piece of revolution.

The potter’s dexterity allows her to free herself from the wheel to produce an almost perfect piece of revolution.

Its positioning reliability is ideal for discs, caps, lids and any revolving part that is not tempered.

After each revolution of the workpiece motor, the carriage is indexed.

To produce rotationally symmetrical surfaces of a workpiece (10), the rotationally driven workpiece (10) is subjected to rotational machining.

The convex, rotation-symmetrical vessel (2) is turned in one piece.

The Revolution of which the play speaks is The Beautiful Non-Violent Anarchist Revolution.

The revolution of which the play speaks is the beautiful, non-violent, anarchist revolution.

The Revolution of which the play speaks is The Beautiful Non-Violent Anarchist Revolution.

The invention also concerns a hollow revolving part manufactured according to the above-mentioned method.

In the course of at least one revolution of the workpiece, the respective positions of the grinding wheel relative to the workpiece are measured for each of a succession of angular positions of the workpiece.

Linear image data processing device for the generatrices of a workpiece having a rotational axis.
