METHOD FOR CONTINUOUS-PATH CONTROL

摘要

The invention relates to a method for continuous-path control by means of a digital control system (5). According to the invention, the speed of the linear axes (X, Y, Z) and of the angle axes (A, B) of a machine-tool (1) is controlled separately. The speed profile of the angle axes (A, B) is then rounded to a greater extent than the speed profile of the linear axes. Positioning errors of the tool (2) in relation to the tool (3) which are produced in this way are corrected by means of compensation shifts in the linear axes (X, Y, Z). This can be advantageously carried out by means of an RTCP unit (6) which is mostly already present in modern multiaxis machine-tools. Improved surface quality or optionally higher machining speed is achieved by means of the reduced accelerations in the angle axes.
