Method for detecting amplitude of ultrasonic cutting tool

Abstract

A method for detecting the amplitude of an ultrasonic cutting tool comprises the following steps: S1, a data acquisition step: applying cutting force to the cutting tool to obtain multiple groups of amplitude data A and electrical parameter data B corresponding to the cutting force; s2, a step of obtaining a function relationship: performing fitting processing on the multiple groups of amplitude data A and electrical parameter data B by data processing software to obtain a function relationship K between the amplitude and the electrical parameters; s3, measuring electrical parameter data: when the cutting tool cuts the material, measuring electrical parameter data B1 of the ultrasonic cutting processing system; and S4, obtaining amplitude data: obtaining amplitude data A1 when the cutting tool cuts the material through the function relation K and the electrical parameter data B1. According to the method, the amplitude of the cutting tool during processing of plastic and brittle materials can be obtained, and the applicability is wide; by means of the method, the real-time amplitude of the cutting tool in the cutting process can be obtained, and timeliness is good.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic assisted machining, and in particular relates to a detection method for the amplitude of an ultrasonic cutting tool. Background technique [0002] Ultrasonic cutting is a technology that transmits ultrasonic vibrations to cutting tools so that the cutting tools can achieve better cutting results. Ultrasonic cutting processing technology has the advantages of high processing efficiency, good processing quality and environmental protection, and is widely used in the processing of hard and brittle materials such as silicon carbide and honeycomb materials. In ultrasonic cutting, the amplitude of the cutting tool directly affects the processing quality and efficiency, and the amplitude of the cutting tool is affected by factors such as load, process, and environment, so the amplitude of the cutting tool is uncertain. Therefore, in processing, it is necessary to measure the vibration amplitude of th...

AI Technical Summary

Problems solved by technology

However, this invention has the following defects: 1. The amplitude of the cutting tool needs to rely on the pit traces left on the surface of the cut material, and when brittle materials such as silicon carbide and honeycomb materials are processed by the cutting tool, the surface of the brittle material cannot be left. Therefore, this method cannot obtain the vibration amplitude when the cutting tool is processing brittle materials. This method is only suitable for measuring the vibration amplitude when the cutting tool is processing plastic materials that are easy to leave the contour of the pit, and has limitations; 2. In this method, the vibration amplitude of the cutting tool is calculated after the cutting is completed, not the real-time amplitude during the cutting process, and the timeliness is poor
