Establishment method of oblique coordinate system of machine tool device being applied to intersection inclined plane

Abstract

The present invention discloses an establishment method of an oblique coordinate system of a machine tool device being applied to intersection inclined planes. The method comprises the following stepsof: S1, input of information of adjacent inclined planes; S2, normal vector of a left inclined plane and normal vector of a right inclined plane; S3, calculation of an intersection line vector; S4, calculation of an oblique workpiece coordinate system; and S5, selection of a coordinate system when production: if the left inclined plane is processed, selecting a coordinate system where the left inclined plane is located, if the right inclined plane is processed, selecting a coordinate system where the right inclined plane is located, and converting coordinates of points in the coordinate systems ML or MR into a general coordinate system of a numerical control machine tool to guide the processing of the numerical control machine tool to the inclined planes. The oblique coordinate system establishment method of the machine tool device being applied to the intersection inclined plane is applied to the inclined plane processing occasions of a five-axis processing center to conveniently arrange an inclination coordinate system of the intersection inclined planes so as to reduce the work difficulty of operators, mitigate the workload, improve the processing precision and achieve a purpose of improving processing efficiency and processing quality of the five-axis processing center processing the inclined planes.

Description

technical field [0001] The present invention relates to a kind of machine tool equipment, more specifically, relates to the machining of intersecting inclined surfaces in a five-axis machining center and similar machine tool equipment. Background technique [0002] The five-axis machining center mainly uses milling cutters to mill fixed workpieces. Milling is the cutting of a workpiece with a rotating, multi-edged tool. Five-axis machining centers include machining centers with three linear axes and two rotary axes. After the workpiece is clamped once, multiple surfaces of the workpiece can be processed. The five-axis machining center has the characteristics of flexible application and high processing efficiency. [0003] When the five-axis machining center processes multiple surfaces of the workpiece, some processing surfaces are inclined, that is, the normal vector of the processing surface and the direction vector of the XYZ axis of the machine tool coordinate system a...

Problems solved by technology

[0008] The operation and calculation of this method are cumbersome and complicated. At the same time, because the coordinate accuracy of the given upper and lower points is four digits after the decimal point, the calculated Z-axis vector of the inclined coordinate system does not completely coincide with the normal vector of the left or right inclined plane. certain angle deviation
