Systems, devices, and methods including selecting one or more sequences of machining types for a feature of one or more features, where the selection of the one or more sequences of machining types is based on the feature and a database of prior selections of machining types; selecting one or more tools for the selected one or more sequences of machining types, where the selection of the one or more tools is based on the feature, the selected one or more sequences of machining types, and a database of prior selections of one or more tools; and selecting one or more machining parameters for the selected one or more tools, where the selected machining parameters are based on the feature, the selected one or more sequences of machining types, the selected one or more tools, and a database of prior selections of one or more machining parameters.

A method for controlling a power tool includes ascertaining a workpiece characteristic of the workpiece to be processed from previously acquired measured values, determining the workpiece material from the workpiece characteristic of the workpiece to be processed, specifying initial values, which are suitable for processing the workpiece made of the determined workpiece material using the power tool, for machine parameters such as feed, speed, and torque, storing the initial values for putting the power tool into operation with machine parameters set to the initial values and/or putting the power tool into operation with machine parameters set to the initial values. A cooling constant is ascertained according to the Newtonian cooling law as the workpiece characteristic of the workpiece to be processed. To ascertain the cooling constant, the ambient temperature is measured, the workpiece is heated, and the actual temperature of the workpiece is measured, whereupon the cooling constant is computed.

A numerical controller includes a data table on which data in which a size of a machining area and a setting value of a parameter, which is influenced by a size of a machining area, are associated with each other is registered. Further, the numerical controller estimates a size of a machining area based on a setting value of a parameter used for control of a machine tool. In the case where data corresponding to the estimated size of the machining area is registered on the data table, the numerical controller acquires a parameter setting value corresponding to the size of the machining area from the data table so as to set the parameter setting value.
