摘要： To smoothen a machining route more appropriately. A numerical controller of the present invention comprises: a machining program look-ahead unit that acquires a program for machining; a command route mathematization unit that expresses a machining route as a parametric line segment or curve on the basis of the program for the machining; and a smoothing processing unit that sets a range of smoothing for a target point of the smoothing along the parametric line segment or curve in an optional range from the target point, and performs the smoothing on the target point on the basis of the set range of the smoothing. The range of the smoothing set by the smoothing processing unit is a range in which a deviation between before the smoothing and after the smoothing on the target point is a set threshold or less.

摘要： A numerical control device for controlling a five-axis processing machine includes a tool-direction instruction correction unit, and corrects a tool-direction vector so that a tool direction of a processing program smoothly changes. The tool-direction instruction correction unit refers to a tool-direction correction tolerance set in advance by a tool-direction correction tolerance setting unit.

摘要： Provided is a numerical control device for improving cycle time and machined surface quality. The numerical control device (1) comprises: a machining program reading unit (10) that generates, on the basis of a read machining program, a tool center point sequence indicating a path of a center point of a tool of a machining tool; an interpolation control unit (11) that interpolates the tool center point sequence generated by the machining program reading unit (10); a kinematic conversion unit (12) that performs coordinate-conversion on the tool center point sequence interpolated by the interpolation control unit (11) to obtain a control point sequence indicating a path of a control point by which the position of the tool is determined; a smoothing application unit (13) that performs smoothing by performing smoothing processing on the control point sequence, obtained by the kinematic conversion unit (12), with predetermined parameters; and a drive control unit (14) that controls driving of a machining tool A on the basis of the control point sequence smoothed by the smoothing application unit (13).

摘要： Provided is a tool-path generating device that includes a point-sequence generating unit that generates a point sequence that represents a tool path on the basis of a machining program, and a smoothing unit that smooths the generated point sequence. The smoothing unit includes a filter-length setting unit that sets filter lengths that are applied to the points such that a pre/post-smoothing divergence amount of each point in the point sequence is equal to or less than a first threshold, a filter-length changing unit that changes the set filter lengths such that an absolute value of a difference between the filter lengths applied to adjacent points in the point sequence is equal to or less than a second threshold, and a filter processing unit that performs filter processing on the basis of the changed filter lengths.

摘要： A numerical controller which controls a five-axis machining machine having two rotary axes generates speed data for deceleration stop along movement paths when a stop signal that requires interruption of machining and retraction is sensed, and based on the speed data, generates stop retraction path command data combining a path for the deceleration stop along the movement paths and a retraction path receding from the movement paths.

摘要： A numerical controller extracts a subsequence from a sequence of command points obtained from a machining program in a manner such that the same path may be created regardless of whether the sequence of command points is extracted from the commanded direction or from the reverse direction. A compressed path approximated by a straight line or a curve is created in a manner such that the compressed path may be approximated by the same straight line or curve regardless of whether the compressed path is created from the extracted subsequence in a commanded direction or in the reverse direction.
