我们提出了一种新的方法来生成2.5D数控铣削刀具路径，具有设计用于减少能源使用的特点。多轴数控铣削中消耗的能量是刀具路径、部件几何形状、数控机床结构和刀具（刀具）本身的函数。在这项工作中，我们只专注于刀具路径的几何形状，并提出了一种新的方法，当所有其他因素保持不变，可以导致刀具路径，需要更少的能量铣削出相同的口袋几何形状。该策略基于选择性松弛的矢量场，专门为待加工的部件设计。试点结果比较使用所提出的战略，使用商业CAM软件产生的刀具路径表明，在能源使用的大量节省的潜力。
We propose a novel method to generate 2.5D CNC milling toolpaths that have characteristics designed for reducing energy usage. The energy consumed in multi-axis CNC milling is a function of the toolpath, component geometry, CNC machine construction, and the tool (cutter) itself. In this work, we focus solely on the toolpath geometry and propose a new method that, when all other factors are held constant, can result in toolpaths that require less energy for milling out the same pocket geometry. This strategy is based on selectively relaxed vector fields, specifically designed for the component to be machined. Pilot results comparing a toolpath generated using the proposed strategy to those generated using commercial CAM software indicate the potential for substantial savings in energy usage.
