Abstract

Tool wear measurements are a significant factor in the operation of an automation machine tool installation. This paper reports four methods for detection of tool wear: cutting force, chip direction, temperature rise and acoustic emission signal. The simple combined measurement method will be used to indicate ceramic tool wear or breakage. Ceramic inserts on a lathe single point cutting were used in the tests at high cutting speed. The true root-mean-square, RMS, of the acoustic emission signal measured at the base of the insert is shown to be the most sensitive to tool wear.

用于指示高速陶瓷镶件磨损的声发射真有效值信号
刀具磨损测量是自动化机床安装运行中的一个重要因素。本文介绍了四种检测刀具磨损的方法:切削力、切屑方向、温升和声发射信号。将使用简单的组合测量方法来指示陶瓷刀具的磨损或破损。在高速切削条件下,采用车床单点切削陶瓷刀片进行试验。在刀片底部测量的声发射信号的真实均方根(RMS)对刀具磨损最为敏感。
