Problems solved by technology

[0006] When such a small reciprocating program command in the tool direction is given, the machine tool repeats deceleration and acceleration corresponding to the speed change of the rotary axis, causing problems such as rough processing or time-consuming processing.

Embodiment Construction

[0030] Image 6 It is a schematic functional block diagram of an embodiment of a numerical control device for controlling a 5-axis machining device according to the present invention.

[0031] A block of an NC program as a machining program is analyzed in the command reading unit 1, and a predetermined thinning process is executed by the thinning unit 2 ( Figure 12 Processes representing flowcharts of algorithms represented in ). For the machine coordinate position of the linear axis and the rotational position of the rotary axis for which the predetermined thinning process has been performed, the interpolation unit 3 performs interpolation processing for obtaining the position of each axis in each interpolation cycle, so that the tool tip point is on the moving path. Move at the commanded relative speed. Then, the servo motors 4x, 4y, 4z, 4b(a), and 4c of the axes are controlled based on the interpolated data in this way.

Abstract

A numerical controller for controlling a five-axis processing machine including three linear axes and two rotational axes for machining a workpiece attached onto a table thins out a command of a moving path of any one of the linear axes and a command of a tool direction if both of the change amount of a tool direction and the change amount of a linear axis in the command of the moving path are smaller than preset values, respectively.

Description

technical field [0001] The present invention relates to a numerical control device, and more particularly, to a numerical control device for controlling a 5-axis machining device that processes a workpiece (workpiece) mounted on a table through three linear axes and two rotational axes. Background technique [0002] In machining using a 5-axis machining device, machining is generally performed in such a way that the movement path of the tool center point (tool center point) and the movement command of the tool direction (tool posture) are determined according to the position of the workpiece and the tool being commanded. The relative movement speed interpolates the tool direction while interpolating the movement path of the tool tip point, and moves on the commanded tool tip point movement path at the commanded speed while changing the tool direction. Machining control based on such commands is called "tool tip point control". The program instructions used in the tool tip p...
