Problems solved by technology

[0005] The purpose of the present invention is to provide an orthogonal turning and milling method for the inner rotary surface, which aims to solve the problem that the existing large-diameter thin-walled parts adopt the orthogonal axial turning and milling method, but for deep hole machining, a special cutter bar is required. The shape and position error of the tool is relatively large, which affects the processing quality of the workpiece

Abstract

The invention discloses an orthogonal turning and milling method for an inner rotary surface. According to the orthogonal turning and milling method for the inner rotary surface, the datum point deviation value and the additional cutter length compensation value of a flat-end milling cutter and a flat-end milling cutter with round corners in the workpiece machining process are acquired, and the additional cutter length compensation value is added to the cutter length compensation function of a numerical control system. By the adoption of the method, the axes of the milling cutters are perpendicular to the inner surface of a part all the time for machining in the machining process, programming efficiency and accuracy are improved, machining quality is guaranteed, and a machining period is shortened.

Description

technical field [0001] The invention belongs to the field of numerical control machining, and in particular relates to an orthogonal turning and milling machining method for an inner rotary surface. Background technique [0002] The structure and shape of thin-walled parts are complex, the requirements for shape coordination are high, the outer dimensions of the parts are relatively large relative to the cross-sectional dimensions, the machining allowance is large, the relative rigidity is low, the processing technology is poor, and the precision requirements are high, and deformation is easily generated during the processing. It directly affects the improvement of the yield rate of mass production of thin-walled parts. Although there have been many reports on the research on the high-speed milling process of aerospace aluminum alloy structural parts, there are still problems of one kind or another in the actual production process, especially the high-speed milling process o...
