PURPOSE:To display position information brought to a reverse conversion, and to grasp easily which part before a conversion is being worked, by storing in advance the contents of a reverse conversion of the same conversion as that which has been applied by an automatic program, etc., in an NC. CONSTITUTION:A microcomputer 1 decodes an NC command program by one block each, calculates a command pulse of each axis by a pulse distribution from a given moving extent, a feed speed, etc., and distributes it to controlling circuits 9-11 of each axis. Subseqently, the microcomputure 1 calculates a cumulative value of the command pulse up to this time by adding the command pulse of this time to a cumulative value of the command pulse to each axis up to the previous time. Also, position information after a reverse conversion is calculated by using said cumulative value and a coefficient K of a reverse conversion stored in a RAM4, and this position information after the reverse conversion is sent out to a position indicator 15, and the display is executed. |
