It is changed into digital picture, and the digital picture passes to central processing unit；Central processing unit, connects and controls the fortune of cutter sweep
Movement controller, motion controller drives operating mechanism, operating mechanism to control the water jet device in it and then cut to workpiece.
Further, video camera and water jet device are connected on operating mechanism, while workpiece is fixed on fixture.
Further, operating mechanism drives video camera and water jet device to be moved between operating mechanism and the witness marker of workpiece
It is dynamic.
The cutting method of above-mentioned diced system, at least comprises the following steps：
S1, recognizes witness marker, before water jet device cutting workpiece, video camera is moved on the witness marker of workpiece, right
The witness marker of workpiece is identified and obtains picture signal, and picture signal is changed into digital picture by image pick-up card；
S2, central processing unit calculates the site error of witness marker and witness marker on template image；
S3, central processing unit corrects graphics processing according to the site error of witness marker, and the graphics processing after correction is transmitted into fortune
Movement controller, motion controller driving operating mechanism makes water jet precisely cut workpiece.
Further, template image is the standard cutting path being set in advance in central processing unit.
Compared with prior art, the beneficial effects of the invention are as follows：The water-jet cutting system of view-based access control model of the invention positioning and
Its method, is identified to the witness marker of workpiece and obtains picture signal using video camera, and image pick-up card is by picture signal
It is changed into digital picture, central processing unit is calculated witness marker on image and is missed with the position of witness marker on template image
Difference；Then, central processing unit corrects graphics processing according to the site error of witness marker, and the graphics processing after correction is transmitted into fortune
Movement controller, drives operating mechanism, water jet is precisely cut workpiece, makes position error less than 0.01mm, makes production
Efficiency improves 50%.
