Abstract

The invention provides a machine tool singular point problem avoiding method and device, electronic equipment and a storage medium. The machine tool singular point problem avoiding method comprises the steps: importing a cutter location point sequence; calculating the cutter axis vector direction change of each cutter location point according to each rotating shaft angle and the change thereof, and calculating the dynamic cutter vector resolution of the current observation point according to each rotating shaft positioning precision and the second rotating shaft angle; if the cutter axis vector direction change of the current observation point is greater than or equal to the dynamic cutter vector resolution of the current observation point, calculating the cutter axis vector direction change and the dynamic cutter vector resolution of the next cutter location point until the last cutter location point; and if the cutter axis vector direction change of the current observation point is smaller than the dynamic cutter vector resolution of the current observation point, adding reverse compensation to the first rotating shaft coordinate value and the second rotating shaft coordinate value of the machine tool, and calculating the cutter axis vector direction change and the dynamic cutter vector resolution of the next cutter location point till the last cutter location point. According to the invention, the singular point is avoided by controlling the angle of the rotating shaft in the machining process.

Description

technical field [0001] The invention belongs to the technical field of five-axis numerical control machining, and in particular relates to a method, device, electronic equipment and storage medium for avoiding the singular point problem of a machine tool. Background technique [0002] In five-axis machining, there is a mapping relationship between the direction of the tool axis vector and the rotation angles of the first and second rotation axes of the machine tool. Generally speaking, the direction of the tool axis vector and the rotation angles of the first and second rotation axes of the machine tool There is a finite mapping, and when the rotation angle of the second rotation axis of the machine tool is 0, the solution of the tool axis vector direction converges to the Z axis of the machine tool coordinate system. Infinite solution phenomenon appears, this point is the singular point, at this point no matter how the first rotation axis of the machine tool rotates, the di...
