Abstract: A control device according to the present disclosure includes a low-pass filter unit that generates a smoothed path by subjecting an indicated path, which is indicated by a control program, to smoothing by a low-pass filter; an inward turning amount calculation unit that calculates an inward turning amount that is the amount of inward turning of the smoothed path generated by the low-pass filter unit relative to the indicated path; and a smoothing processing unit that outputs a path obtained by turning back the smoothed path in a direction opposite to the inward turning direction on the basis of the inward turning amount.

Abstract: A numerical controller that creates a tool path from a plurality of command points includes: a command point sequence acquisition unit that acquires an existing command point sequence; a command point creating unit that creates at least one additional command point, based on the existing command point sequence; and an interpolation processing unit that interpolates the existing command point sequence and the additional command point to create the tool path. The command point creating unit outputs, as the additional command point, an intersection point Q1 between an arc C1 passing through consecutive three command points, P0, P1 and P2, in the existing command point sequence and a perpendicular bisector of a line segment whose end points are P1 and P2.

Abstract: A numerical controller includes a reading analysis unit that reads a CNC program and additional information, a path generation unit that determines a movement path of a tool, and a velocity control unit that determines a velocity for moving the tool according to the movement path of the tool, and machining errors, deterioration of a machined surface quality, or an increase in a cycle time are reduced without increasing a CNC program size and a calculation time associated with control more than necessary.
