Numerical control device to change parameter using NC program

A numerical control device configured to change parameter using NC program, comprising:

• an NC program storing unit configured to store the NC program including a parameter rewriting command for changing a parameter set in the numerical control device;
• a parameter storage unit configured to store a plurality of parameters of the numerical control device;
• a numerical control device manipulation unit configured to acquire, from an operator, a parameter to be changed and a value of the parameter to be changed, and configured to send a command to rewrite the parameter value of the received parameter to be changed;
• a parameter change unit configured to specify the parameter to be changed from the plurality of parameters stored in the parameter storage unit based on the acquired parameter received from the operator, and configured to rewrite the specified parameter to the acquired parameter value;
• a parameter change monitoring unit configured to detect a change of the parameter by monitoring the parameter change unit, and configured to output a command for starting the NC program based on the detected change of the parameter;
• and
• an NC program execution unit configured to execute the NC program based on the command from the parameter change monitoring unit.
