Numerical control system for a more axes machine for machining of an inclined machining plane

摘要

Numerical control (100) for controlling a more axes machine, the at least three linear axes (x, y, z) for controlling the position of a tool relative to a workpiece is used, which is mounted on a table, and at least three axes of rotation (a, b, c) for controlling the orientation of the tool relative to the workpiece, in order to achieve a machining process on an inclined machining plane of the workpiece, and the numerical control (100) comprises:a feature - coordinate system - command - analysing means (84) for analyzing of a command of a feature - coordinate system (xf, yf, zf), which is a for the inclined machining plane of the workpiece coordinate system is representative;a tool - coordinate system - control command - analysing means (85) for analyzing a tool - coordinate system - open loop command, which a command for controlling the three axes of rotation (a, b, c), so that the three orthogonal axes of a tool - coordinate system (xt, yt, zt), which lies on the tool and moves, when the tool is moved, parallel to the three orthogonal axes of the feature - coordinate system (xf, yf, zf); a three - axes of rotation - calculating means (86) for calculating the respective positions of the three axes of rotation (a, b, c), so that the three orthogonal axes of the tool - coordinate system (xt, yt, zt) parallel to the three orthogonal axes of the feature - coordinate system (xf, yf, zf) are in the form of response to the tool - coordinate system - control command; andMeans for driving the three axes of rotation (a, b, c) to the positions of the three - axes of rotation - calculating means (86) were obtained.
