On-line detection method for non-contact cutter blade wear

Abstract

The invention relates to an on-line detection method for non-contact cutter blade wear. The method mainly solves the problem that in existing V groove machining, wear of a cutting edge at the sharp corner of a cutter blade can not be accurately detected, and consequently the workpiece machining precision is low. The method is characterized in that a computer (1) is connected with a machine tool numerical control system (2) and an industrial camera assembly (3) through ports respectively, the industrial camera assembly (3) is fixed to an arm joint of a mechanical arm (4), and a lens of the industrial camera assembly (3) is aligned with the V groove sharp corner of a workpiece (5). According to the on-line detection method for non-contact cutter blade wear, by accurately detecting the precision of the V groove sharp corner of the workpiece, the degree of wear of the cutting edge at the sharp corner of the cutter blade is judged, and cutter blade grinding or replacing work can be adopted in time.

Description

technical field [0001] The invention relates to the field of mechanical processing equipment, in particular to a non-contact online detection method for blade wear. Background technique [0002] During V-groove processing, the cutting edge at the sharp corner of the insert wears much faster than the cutting edges on both sides. With the increase of processing time, the cutting edge at the sharp corner of the insert will first enter the sharp wear stage due to stress concentration. , due to the very small size of the sharp corner of the V groove of the processed part (R0.25±0.025), it cannot be measured with the naked eye or ordinary inspection tools (such as micrometers, angle gauges, etc.), and at this time the blades on both sides of the V groove are cut The blade is still in the normal wear stage. In actual production, it is always judged whether the tool has been blunted according to some phenomena that occur during the cutting process, such as observing the color and s...

Problems solved by technology

[0003] In order to overcome the problem that the cutting edge wear at the sharp corner of the blade cannot be accurately detected during the existing V-groove processing, which leads to low machining accuracy of the workpiece, the present invention provides a non-contact online detection method for blade wear. The on-line detection method accurately detects the accuracy of the V-groove sharp corner of the workpiece, thereby judging the wear degree of the cutting edge at the sharp corner of the blade, and can use blade grinding or replacement work in time
