Abstract

The invention discloses an internal rotation surface orthogonal turning-milling machining tool length compensation algorithm. A milling tool end surface center point serves as a tool location point, a workpiece contour programming method remains unchanged, and according to orthogonal turning-milling internal surface machining characteristics and the deviation value between the tool location point and a machining datum point, an additional length compensation amount for the tool is calculated. The tool length compensation function is integrated in a numerical control system, the axis of the milling tool is constantly vertical to the internal surface of a spare part during the machining process for machining, the programming efficiency is improved, the machining period is shortened, and the machining quality is ensured.

Description

technical field [0001] The invention belongs to the field of numerical control machining, and in particular relates to a tool length compensation algorithm for orthogonal turning and milling of 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-spe...
