Method for Determining the Main Parameters of an Optical-Electronic Inspection System for Shells During Sheet Bending Machine Processing

A method for calculating the main parameters of an optoelectronic system for monitoring shells the key basic components of largescale products in chemical, oil, and power engineering is presented. A mathematical model of the optical measurement scheme is developed, which makes it possible to analytically define the main parameters of the system determined by the technology used in the production of shells during roll sheetbending machine processing. These parameters make it possible to determine the depth of field of the optical system and the dynamic characteristics of the system. Graphical relationships are obtained that show how the parameters of the optoelectronic control system depend on ovality the main form of deviation from cylindrical shape, which enables reasonable selection of the system parameters for a specific technological process. The obtained dependencies are analyzed, and the possibility of simplifying them for the case of low ovality of the shells are demonstrated. The proposed method is also applicable for controlling cylindrical parts with a different number of faces, which expands the scope of use of the method in automated control systems for sheetbending equipment.
