The invention provides a radius compensation method for a turning tool of a turning and milling composite machine tool. The radius compensation method comprises the steps that the radius of the turning tool and the accurate stop deviation angle of a spindle are obtained; an oblique coordinate system is built according to the radius of the turning tool and the accurate stop deviation angle of the spindle; the coordinate point of the current position of a tool point of the turning tool under a workpiece coordinate system is converted into the oblique coordinate system; according to the coordinate point of the current position of the tool point of the turning tool under the oblique coordinate system, the coordinate point of the target position of the tool point of the turning tool under the oblique coordinate system and the feeding speed of the machine tool, the compensation coordinate values, corresponding to all interpolation cycles, of the turning tool under the oblique coordinate system are calculated; the compensation coordinate values of the turning tool under the oblique coordinate system are converted into the workpiece coordinate system; and the turning inner circle of the machine tool is controlled according to the compensation coordinate values under the workpiece coordinate system. The radius compensation method expands the application occasions of turning of the turning and milling composite machine tool and improves the production efficiency and machining quality.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of tool radius compensation for machine tools, and in particular, to a method for compensating tool radius for turning and milling compound machine tools. Background technique [0002] Lathe processing mainly uses turning tools to turn rotating workpieces. Milling is the cutting of a workpiece with a rotating, multi-edged tool. The composite machine can combine several different processing techniques on one machine tool. The combined turning and milling process refers to a process that can perform both milling and turning. A machine tool that can perform both milling and turning, here specifically refers to the AC double turntable five-axis linkage turning-milling compound machine tool. When using the turning tool, the turntable of the machine tool switches to the function of the lathe spindle, and the machine tool can perform turning processing. After replacing it with a milling cu...
