本文提出了一种用于五轴加工的刀具轨迹实时生成和控制的新方法。该刀具轨迹生成方法包括刀具-接触轨迹插补、刀具偏置和坐标转换的实时算法。另外，为了提高实际刀具轨迹生成的受控精度，通过数控插补器实现了全局反馈环的闭合。给出了控制回路的误差补偿算法和进给速度自适应算法。(C)1998爱思唯尔科学有限公司。保留所有权利。
This paper presents a new approach to real-time generation and control of the cutter path for 5-axis machining applications. The cutter path generation method comprises real-time algorithms for cutter-contact path interpolation, cutter offsetting, and coordinate conversion. In addition, a global feedback loop is closed by the CNC interpolator so as to augment the controlled accuracy in practical cutter path generation. An error compensation algorithm and a feedrate adaptation algorithm for the control loop are developed, respectively. (C) 1998 Elsevier Science Ltd. All rights reserved.
