ABSTRACT:
A numerical controller with a program resuming function of acquiring program-resuming block data with which a machining program is resumed without producing a scratch on a workpiece. It is determined whether there are registered non-cutting commands. Whether all the registered non-cutting commands are analyzed is determined. Data of registered non-cutting command is read, and whether a block currently being analyzed includes a non-cutting command is determined. It is determined whether or not the registered non-cutting command is one in accordance with which data is acquired at a block start point. Program-resuming block data is acquired at the block start point or at a block end point, the acquired data is stored into a memory, and a process is completed.
