Bull-nose-shaped milling cutter damage detection system in rough machining process of three-dimensional impeller

Abstract

The invention provides a sound emission signal collection device and a bull-nose-shaped milling cutter damage quantitative analysis module in a rough machining process of a three-dimensional impeller. The sound emission signal collection device is formed by a sound emission sensor, a sensor clamp, a prepositioned amplifier, a sound emission collection card, a portable industrial personal computer and AEwin data collection software. The sound emission sensor is fixedly arranged on an impeller to be machined through the sensor clamp; an analogue signal is amplified and converted into a digital signal by the prepositioned amplifier and the sound emission collection card to be transmitted to the portable industrial personal computer; and then the digital signal is subjected to signal display and data storage by the AEwin software. The bull-nose-shaped milling cutter damage quantitative analysis module disclosed by the invention processes a collected sound emission signal and a bull-nose-shaped milling cutter damage state is subjected to quantitative analysis.

Description

technical field [0001] The breakage detection system of the bullnose milling cutter in the rough machining process of the ternary impeller according to the invention belongs to the field of equipment fault detection, and relates to the breakage detection system of the bullnose milling cutter blade in the rough machining process of the ternary impeller.

Problems solved by technology

However, when the machine is stopped for inspection and then restarted, the error of receiving the tool will inevitably affect the machining accuracy; while observing the chip state, the power discrimination method, and the noise discrimination method are not very intuitive, and it is difficult to replace the blade at the best time.
