A numerical control device includes: a switching unit switching between a first processing mode in which a position command for an amplifier is generated by performing interpolation process and acceleration/deceleration process on a program command in a machining program, and a second processing mode in which a position command every intra-amplifier control cycle for the amplifier is generated by performing acceleration/deceleration process on a command generated every intra-amplifier control cycle, which is a control cycle in the amplifier; a normal analysis unit extracting movement data on a machine tool by analyzing the program command when operating in the first processing mode; an interpolation processing unit obtaining first interpolated data by performing the interpolation process on the movement data when operating in the first processing mode; and a fast analysis unit extracting interpolated movement data as second interpolated data by analyzing the program command when operating in the second processing mode.

Various embodiments of the present disclosure are directed to a method for carrying out a test run on a test stand. The method in some embodiments reduces a deviation between a comparison simulation value and a comparison reference value when carrying out a test run on a test stand with a test object by simulating via a simulation unit a number of simulation values using a number of specified reference values starting from a selected reference value, determining a corrected reference value which is specified to the simulation unit for simulating a corrected simulation value and determining at least one setpoint variable using the corrected simulation value.

A computer system may determine a target position of the electronic component. The computer system may also determine a current position of the electronic component. The computer system may compare the current position to the target to position to determine whether the electronic component is in the target position. If the electronic component is not in the target position, the computer system may use an electroactive polymer to adjust the position of the electronic component to move the electronic component into the target position.

A numerical controller for controlling a machine receives an instruction to reestablish a machine coordinate value of a movable part of the machine and stops a servo motor driving the movable part. When the servo motor is stopped, the numerical controller acquires position information of a position detector provided to the servo motor. Then, the numerical controller updates the machine coordinate value of the movable part based on the position information, and further updates the absolute coordinate value of the movable part based on the updated machine coordinate value.
