Numerical control device

A non-transitory computer readable medium storing instructions to be executed by a numerical control device, which controls a machine tool and at least one peripheral device placed around the machine tool, wherein the instructions when executed by the numerical control device cause the numerical control device to implement the following operations:

• store operation patterns each including commands for causing operations by the peripheral device to be executed, the commands using configuration of a shaft of the peripheral device, M code unique to the numerical control device, or moving amount of the peripheral device as variables;
• store machine information in which a value with respect to each of the variables is specified for the shaft of the peripheral device or for the unique M code;
• receive a numerical control program which is executed by the numerical control device to control the machine tool via a first controller and the at least one peripheral device via a second controller,
• when a command in the numerical control program is a command for the machine tool, deliver the command to the first controller, and
• when the command is a command for the peripheral device including a first argument indicating an operation pattern from among the stored operation patterns and a second argument indicating a moving amount of the peripheral device, acquires the operation pattern corresponding to the first argument from the stored operation patterns, and delivers the operation pattern to the second controller together with the moving amount indicated by the second argument,
• wherein the second controller generates a peripheral device command by substituting the corresponding machine information or the acquired moving amount for each of the variables in the commands constituting the acquired operation pattern, and
• wherein the first controller generates a move command with respect to the machine tool or the shaft constituting the peripheral device from a command in the numerical control program or the peripheral device command,
• wherein the instructions further comprise store operation information specifying operations of the peripheral device or a constituent member of the machine tool that is located at a position interfering with the peripheral device,
• wherein the variables in the operation patterns further include operations with respect to the peripheral device or the constituent member of the machine tool that is located at a position interfering with the peripheral device, and
• wherein the second controller substitutes the corresponding machine information, the acquired moving amount, or the corresponding operation information for each of the variables in the commands constituting the operation patterns, to generate the peripheral device command.
