Provided is a heat-shrinkable polyester film whose main shrinkage direction is the machine direction. This film does not shrink in the machine direction in a low-temperature region and, despite this, highly shrinks in a high-temperature region. The film has an extremely high mechanical strength in the transverse direction, which is perpendicular to the main shrinkage direction. The film is suitable for use especially as a film for forming covering labels for dry cells and in applications similar thereto. The heat-shrinkable polyester film shrinks mainly in the machine direction. The film has been regulated so that the degree of machine-direction hot-water thermal shrinkage through 10-second immersion in 80 DEG C water is in a given range and the degree of machine-direction thermal shrinkage and degree of transverse-direction thermal shrinkage through 10-second immersion in a 140 DEG C glycerol bath are in respective given ranges.

The present invention provides a finishing machine characterized in that useless burr removing actions can be reduced and, further, that the overcutting of a workpiece can be prevented. A surface of a workpiece, from which the burr is removed, is traced when a machining tool is pressed onto the surface of the workpiece under force control so as to find the positional data of the surface shape. This positional data is corrected by an error caused by a bend of a robot. The thus obtained positional data is compared with the target shape of the surface, from which the burr is removed, obtained from CAD data. A shift of the surface shape in the normal line direction is found. The burr generation start position, the burr generation end position and the height of the burr are found by the shift start position, the shift end position and the shift size. A machining program is made which is composed of a pass connecting the burr end position with the burr start position and also composed of a cutting pass for removing the burr, and the thus made machining program is executed. As the burr position is found and the burr is removed when the machining tool is moved to the burr position, the burr can be effectively removed.
