Metal cutting is the basis of modern manufacturing, and tool failure is one of the most common and costly failures in metal cutting. In the cutter production process, errors in any link can possibly cause that the surface quality and the dimensional accuracy of the cutter cannot meet the requirements, and if the unqualified cutter participates in the cutting machining process, adverse effects can be caused on the quality, the efficiency and the economic benefit of the workpiece. Therefore, the method has important practical significance in checking the qualification of the cutter before the cutter leaves the factory, not only can prevent the unqualified cutter from flowing out, but also can push the improvement of the cutter production process in turn.

step S4, controlling the cross sliding table (20) to drive the visual detection device to move to an initial position and shoot an image of a tool nose area, and then driving the visual detection device to move by the cross sliding table (20) so that the industrial camera (3) detects the tool nose at the other side of the upper surface of the tool (18) and shoots an image;
s5, after surface images of eight cutter surfaces of the cutter (18) are acquired and transmitted to a computer, the computer analyzes the defect condition of the cutter (18) surface reflected by the images, judges whether the cutter (18) is qualified or not according to a threshold preset by an operator according to detection requirements, and feeds back an analysis result to the full-cutter surface defect quality detection device;
s6, rotating a rotary table (9), moving a storage table (17) positioned at a detection station to a sorting station, then lowering a manipulator (6) of a cutter sorting device along a sorting mechanical table (11) to a height, then clamping a cutter (18), then lifting the manipulator (6) to an initial position along the sorting mechanical table (11), and rotating the upper part of the sorting mechanical table (11) anticlockwise if the cutter (18) is qualified, or else rotating clockwise; after rotation, the manipulator (6) releases the cutter (18), and the cutter (18) is placed in a storage box which is placed in advance;
and S7, rotating the rotary table (9), moving the object placing table (17) positioned at the sorting station to the cutter mounting station, and repeating the steps.
