提高加工机械的产量通常应通过提高机器的运行速度来实现。随着运行速度的增加，在机器或过程中会出现不期望的影响，例如限制运行速度的振动。本文讨论了一些选定的原因，可能会发生在加工机器上的限制。一个已经开发的方法来处理的问题是不久。讨论了为什么它在某些过程中有效，而在其他过程中无效。因此，现有的方法是扩展的自适应插值方法，处理不断变化的工作速度。这一扩展的效果是，新方法的优点可以适用于迄今为止支持不足的进程。通过这种方法，可以减少运动优化和路径准备的计算工作量。由此产生的数据量也大幅减少。最后，一个验证的数值模型的过程模拟证明了新的插值方法的优点。
Increasing the output of a processing machine should often be achieved by increasing the machine’s operating speed. Associated with the increasing operating speed are undesirable effects occurring on the machine or process, e.g. vibrations that limit the operating speed. This paper discusses some selected causes for limitations that may occur on processing machines. An already developed approach to dealing with the problems is shortly presented. It is discussed why it is effective in some processes but not in others. Consequently, the existing approach is extended by an adaptive interpolation approach that deals with the changing operating speed. This extension has the effect that the advantages of the new approach can be applied to processes that have been insufficiently supported so far. With this approach, the calculation effort for motion optimization and path preparation can be reduced. The resulting amount of data decreases significantly as well. Eventually, the advantages of the novel interpolation approach are demonstrated by a process simulation with a validated numerical model.
