METHOD FOR CONTROLLING HYDAULIC ABRASIVE CUTTING OF SHEET MATERIALS Russian patent published in 2003 - IPC

FIELD: optimization of technological parameters at cutting construction materials. SUBSTANCE: method comprises steps of feeding cut material and supplying on it working liquid through fluidic head; measuring vibration of fluidic head at cutting process during emitting liquid out of it by means of optical solid laser base measuring system having high-response diode matrix, for example on base of charge coupled device; changing pressure of working liquid in dependence upon vibration value according to feed of cut material. EFFECT: desired micro- and macrogeometry of cut lines and stripeness of surface, enhanced efficiency of method. 3 dwg, 1 ex
