| 摘要 |
The invention relates to a measuring machine or machine tool, or a method for operating such machines, having redundant translatory axes for a substantially continuous motion on arbitrarily complex paths, the longer partial axes each allowing a relatively low-acceleration partial motion over a relatively large measuring or machining space, and the shorter partial axes each performing substantially only the partial motions of an overall motion having a substantially net constant measuring or machining velocity, requiring acceleration beyond a maximum determined or set for each longer partial axis, characterized in that the acceleration of each shorter partial axis determines the potential acceleration during the overall motion having said substantially constant measuring or machining velocity on an arbitrarily complex path, wherein the range of motion of the shorter partial axes as a distance must substantially suffice in order to perform at least one complete change in sign of the velocity of motion at said aspired constant velocity having said maximum acceleration of the longer partial axis, and the maximum velocity of motion of the shorter partial axis must be at least nearly double that of the aspired constant velocity. |
