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 user manually operates the probe of a machine tool to move toward a workpiece. A movement history of the user's manual operation is recorded. The positional relationship between a workpiece and the probe is estimated based on the history of movement of the probe by the manual operation. The controller presents a candidate for the direction of the probe to be moved in the automatic measurement of the workpiece. The user inputs the movement direction of the probe with reference to content of the presentation.
