The present invention relates to numerical controller having a function for collecting the data regarding machining without using external devices such as data logger and outputting the data in batch. The numerical controller comprises collection/output control unit configured to provide an interface for setting the collection information defining collection condition of the numerical control data and the peripheral equipment data and aggregation information defining the aggregation condition upon aggregating the and the peripheral equipment data and an interface for outputting the produced process data; data management unit configured to collect the numerical control data in accordance with the collection information; data collection unit configured to collect the peripheral equipment data from the peripheral equipment in accordance with the collection information; and data aggregation unit configured to produce the process data obtained by aggregating the numerical control data and peripheral equipment data in accordance with the aggregation information.

A device for dynamically generating numerical controller software of machine tool includes a software function-specification managing unit, a function-module storage unit and a function-module composing unit. The software function-specification managing unit is to produce a text description file describing function modules required by the numerical controller software, and then for performing specification analysis upon the text description file to generate a function module table including the function modules. The function-module storage unit is to memorize and manage the function modules, wherein the function-module storage unit confirms whether or not the function-module storage unit has been furnished with the f function modules required by the numerical controller software. The function-module composing unit is to retrieve the required function modules from the function-module storage unit, and further to set the connection among the function modules to compose the numerical controller software. In addition, a method for the device is also provided.
