ABSTRACT:
When a read block includes a code for setting a machine coordinate system used for exchanging a tool or the like, it is determined whether a feed rate specifying modes, set by a parameter, is (a) specification by using parameters, (b) specification by a program, or (c) specification by using an external signal input. In mode (a), the rapid traverse speed set for movement according to machine coordinate system or different feed rate set by a parameter is selected and set as feed rate F. In mode (b), a feed rate specified by a program is set as feed rate F. In mode (c), an input signal is converted into a speed which is set as feed rate F. Then the movement command according to the machine coordinate system is executed with this set feed rate F.
