Abstract

The invention provides a cutter abrasion on-line monitoring method to monitor cutter abrasion of a lathe in the machining process on the basis that considering the influence of the cutter abrasion capacity and machining parameters on cutting power, a corresponding regression model is established, namely the invention discloses a cutter abrasion on-line monitoring method of numerical control turning batch machining based on the cutting power. The method comprises the following steps that firstly, the influence of the cutter abrasion capacity and the machining parameters on the cutting power is analyzed; then the regression model of the cutting power, the cutter abrasion capacity and the machining parameters is established through orthogonal test design and a response surface method; and finally, on the basis of establishing of the regression model of the cutting power, the cutter abrasion capacity and the machining parameters, the cutter abrasion on-line monitoring method where a cutting power threshold value is updated in real time is obtained.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to an on-line monitoring method for tool wear in numerical control turning batch processing based on cutting power. Background technique [0002] During the batch processing of CNC turning, excessive tool wear will affect the surface quality and machining accuracy of the workpiece; at the same time, as the amount of turning tool wear increases, the machine tool will consume more energy. Industrial statistics show that tool failure is the primary factor causing machine tool failures, and the resulting downtime accounts for 1 / 5 to 1 / 3 of the total downtime of CNC machine tools. Therefore, on-line monitoring of tool wear in the batch machining process of CNC turning is an urgent scientific problem that needs to be solved under the background of intelligent manufacturing. [0003] According to different measurement methods, tool wear monitoring methods can be divided into direct me...
