<P>PROBLEM TO BE SOLVED: To provide a cutting machine and an emergency stop method of a motor, capable of eliminating the necessity of capturing and processing an image for emergency stop of the motor and reducing complicatedness of setting the detection range of an object. <P>SOLUTION: A first sensor 11 measures a distance between itself and an object 9. Specifically, the first sensor 11 emits an electromagnetic wave, receives the electromagnetic wave which is emitted by the first sensor 11 and reflected by the object 9 or an electromagnetic wave emitted by the object 9 that has received the emitted electromagnetic wave, and specifies the distance between itself and the object 9 based on a time difference between the emission and the reception of the electromagnetic wave. A second sensor 12 and a third sensor 13 measure distances between themselves and the object 9 as in the case of the first sensor. A control section 3 specifies three-dimensional coordinates of the object 9 based on the distances between the respective sensors and the object 9, determines whether or not the three-dimensional coordinates of the object 9 fall within a predetermined region, and stops a motor when the three-dimensional coordinates of the object 9 fall within the region. <P>COPYRIGHT: (C)2013,JPO&INPIT |
