Compensation of tool deflection based on drive currents

在铣削加工过程中，由加工力引起的刀具偏转严重影响加工精度。该转移项目对N1项目中开发的刀具偏转补偿方法和知识进行了扩展和转移。该项目由DECKEL MAHO Seebach GmbH合作完成。目标是将加工精度提高80%。为了实现这一目标，从驱动电流估计过程力，并与机床控制的插补周期同步计算挠度。项目N1的自适应控制策略被应用于最小化由此产生的路径偏差。为了保证其工业实用性，本文还开发了过程参数化的自主识别程序和启发式方法。最后，与转让伙伴密切合作，在技术和经济方面验证该系统。

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.
