基于切削力的铣刀破损实时监测技术研究

On-line Monitoring of Cutting Tool Breakage in Milling Operation Based on Cutting Force

介绍了铣削过程刀具破损监测系统，分析了刀具破损和特殊切削条件下切削力的波形特征，阐述了两者变化规律的不同．引入自回归算法对刀具破损进行识别，用实验方法确定了破损门坎值．

This paper presents the system of tool breakage monitoring in milling. The difference of characteristic of cutting force wave - form after tool broken and under special conditions was analyzed. Autoregressive algorithm was used to identify the tool breakage, and the limited value was defined through the experiments.
