Compensation of tool deflection based on drive currents

基于驱动电流的刀具偏转补偿

基本信息

项目摘要

Tool deflection, caused by process forces, severely affects machining accuracy in milling processes. This transfer project extends and transfers the methods and knowledge on compensation of tool deflection, which were developed in the project N1. The project is conducted in collaboration with DECKEL MAHO Seebach GmbH. The goal is to increase machining accuracy by up to 80%. To achieve this, process forces are estimated from drive currents and deflection is calculated synchronously to the interpolation cycle of the machine tool control. The adaptive control strategies from project N1 are applied to minimize the resulting path deviation. In order to ensure industrial practicability, autonomous identification routines and heuristics for process specific parametrization are developed as well. Finally, the system is validated in technical and economic terms in close collaboration with the transfer partner.
在铣削加工中,由于加工力的作用,刀具变形严重影响加工精度。该转移项目扩展并转移了在项目N1中开发的关于刀具偏转补偿的方法和知识。该项目与DECKEL MAHO Seebach GmbH合作进行。目标是将加工精度提高80%。为了实现这一点,过程力从驱动电流估计,并且与机床控制的插补周期同步地计算偏转。从项目N1的自适应控制策略,以尽量减少所产生的路径偏差。为了确保工业实用性,自主识别例程和过程特定的参数化的算法也被开发。最后,与转让伙伴密切合作,从技术和经济角度验证该系统。
