METHOD OF MAKING DISCRETE SHAPED STRUCTURE OF FUNCTIONAL LAYER OF PRINTING PATTERN AT COMPUTER-AIDED ETCHING HARDWARE-SOFTWARE COMPLEX Russian patent published in 2012 - IPC B23D5/02 B41C1/45 

FIELD: process engineering.

SUBSTANCE: proposed method comprises major displacement of tool and surface of printing pattern functional layer. For this used is XYZ tool displacement actuating system. Cutting toll is displaced in the field of vision of computer TV microscope to register its cutting part at stationary check position and to register, by software means, tool tip vertical coordinate Z relative to reference plane with coordinate Z₀. Printing pattern functional layer is used as said reference plane. Note here that said coordinate Z₀ simultaneously with coordinate Z₁. Note here that constants ΔZ_const=Z₁-Z₀ are loaded into control program bank for entire cycle of given process. Actuating system control program is configured to allow video control, in present time intervals, over tool cutting edge wear and current coordinate R_t of tool tip relative to coordinate Z₀. For this, cutting tool is lifted from current operating position and displaced into filed of vision of TV computer microscope to position corresponding to aforesaid stationary initial position. Then, ΔZ_T=Z_T-Z₀ is registered by hardware means. ΔZ_T is compared to ΔZ_const. Control program is subjected to time correlation in coordinate Z by ΔZ_T=Z_T-Z₀. Thereafter, tool is moved back into initial position. Note here tool cutting tool is cleaned of micro particles of machined material prior to feeding tool cutting edge into field of vision of said microscope. Besides, in case tool integrity or wear are revealed by hardware means, tool is automatically replaced. Here, ΔZ is defined by Z with respect to tip of new tool.

EFFECT: higher precision and quality.
