Abstract

Data accommodated in a plurality of successive blocks specified by a registration command is converted into an execute form and prestored in storage means. In response to an execution command, control is performed in accordance with the stored data. In the case of executing in succession a plurality of blocks each having a short execution time, data in the blocks is converted into the execute form and stored. This eliminates the time for the data conversion, and hence permits continuous movement of a movable machine part.

Claims

1. Numerical control system for controlling a movable machine in accordance with a numerical control (NC) program including command data, said system comprising:

means for reading blocks of command data including a registration start block having a registration number, a registration end block and an execution start block having a registration number;

converting means for converting, while controlling the movable machine, a plurality of blocks of the command data into execute form data in response to the registration start block and the registration end block;

storage means, having a plurality of registration areas, for storing the execute form data in a registration area specified by the registration number of said registration start block; and

control means for controlling the movable machine in accordance with execute form data stored in one of said registration areas specified by a registration number of an execution start block.
