Information processing device

A machining system comprising:

• an information processing device including a processor;
• and
• a plurality of numerical controllers for controlling a machining tool, the plurality of numerical controllers including a processor;
• wherein the information processing device is connected to the plurality of numerical controllers via networks,
• the processor of the information processing device is configured to:
• collect programs entered in the plurality of numerical controllers, the programs each including a command and an address for controlling the machine tool;
• count a number of the programs entered in the numerical controller based on the collected programs and create ranking information by scoring the program, the ranking information being obtained based on a counting result;
• distribute the ranking information to the plurality of numerical controllers;
• and
• regard blocks that include the same command and the same type of address as the same program when counting the number of the input programs;
• and
• the processor of the plurality of the numerical controllers is configured to:
• in response to a user entering a character into the numerical controller, performs forward matching of the entered character based on the ranking information to determine and display a ranked command that includes the entered character, the ranked command associated with a program of the collected programs, and
• in response to a user selecting and executing the ranked command, control the machining tool based on the associated program.
