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.

一种用于在加工机器中实现与运行速度相关的运动曲线的新型自适应插值方法

通常应通过提高机器的运行速度来提高加工机器的产量。与增加的运行速度相关的是机器或过程中出现的不良影响,例如限制运行速度的振动。本文讨论了加工机器上可能出现的限制的一些选定原因。不久将介绍一种已开发的处理问题的方法。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,现有方法通过处理不断变化的操作速度的自适应插值方法进行扩展。这种扩展的效果是,可以将新方法的优点应用于迄今为止尚未得到充分支持的流程。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显着减少。最后,新型插值方法的优势通过具有经过验证的数值模型的过程模拟得到证明。
