PURPOSE: An unmanned control method for automating of machine tool is provided to manlessly automate without a memory unit of large capacity by minimizing a capacity of a processing program. CONSTITUTION: A computer reads a waiting pallet number of an automatic pallet exchanger through a common communication protocol through a numerical value control unit. A processing program corresponding to the waiting pallet is searched in a program storing unit of the computer. An existence of the processing program is checked. If the processing program is not stored in the storing unit of program, a host computer downloads the stored processing program of the computer to store in a program storing unit of machine. When the host computer recognizes a normal finishing signal of download in the machine, every program are deleted except the present processing program and the downloaded corresponding processing program of the waiting pallet. The present processing program and the downloaded processing program are performed. And an early step is repeated. When the processing program is existed in the machine, the download is not performed and the repeating is performed. When the normal finish of download is not existed, an alarming is performed.
