Abstract: A device comprises: a calculation unit calculating, based on a model on a calculator, a response path along which a target actually operates when an instruction path is given; a determiner determining a target path along which the target operates; a generation unit regenerating a temporary instruction path based on the target path and a temporary instruction response path obtained when the calculation unit is given the temporary instruction path; a determiner determining a convergence determination condition; and a comparator determining whether error between the temporary instruction response path and the target path is converged, based on the condition. Regenerating the path and calculating the temporary instruction response path are repeated until the comparator determines that the condition is met, and, when the comparator determines so, the temporary instruction path is output to a controller controlling the target, as the path for operating the target.

Abstract: A command value generator includes: a target path and tolerance range changing unit changing at least one of the target path and a range of tolerance based on the machining error; a response path calculation unit calculating a response error and a response path; a path comparison unit calculating an error between the response path and the target path and determining whether the calculated error falls within the range of tolerance; a temporary command path holding unit holding the target path as a temporary command path; and a command path correction unit correcting the temporary command path. The temporary command path is corrected based on the response error when determining the calculated error not to fall within the range of tolerance, and a corrected temporary command path is held in the temporary command path holding unit.

Abstract: An instruction value generation device comprises: an instruction response calculation unit (102) that predictively calculates, on the basis of a model on a calculator, a response path along which a control target is actually operated when an instruction path is given; a target path determination unit (104) that determines a target path along which the control target is operated; an instruction path generation unit (105) that regenerates a temporary instruction path on the basis of the target path and a temporary instruction response path obtained when the temporary instruction path is given to the instruction response calculation unit (102); a convergence-determination-condition determination unit (103) that determines a convergence determination condition used in a determination processing of determining whether an error between the temporary instruction response path and the target path is converged; and a path comparison unit that performs the determination processing on the basis of the convergence determ

Abstract: In a numerical control data forming system for a numerical control unit which is operated with a display unit and a data inputting unit, and has an automatic programming function to form machining data for a machine tool, the automatic programming function includes the operation that, in defining a machining configuration, the coordinates of a temporary last point are inputted, and the coordinates of an actual last point are automatically calculated, whereby numerical control data can be readily formed.
