| 20140088755 | NUMERICAL CONTROLLER WITH INTER-PATH WAITING FUNCTION - A pre-read/analysis process is carried out to analyze a code in a block, and whether or not the analyzed data contains an inter-path waiting code is determined. When the block contains an inter-path waiting code, the pre-read/analysis process is suspended, and whether or not a preset specified condition is met is judged. When the specified condition is met, inter-path waiting is started.
