20.500.12556/RUL-121800 Nadgradnja in analiza sistema za stalni nadzor hladilno mazalnih emulzij pri odrezovalnih procesih Upgrade and analysis of the system for constant monitoring of cooling and lubricating emulsions in machining processes V odrezovalnih procesih so hladilno-mazalne emulzije ključni element za zagotavljanje dobrega delovanja procesov. Za ustrezno delovanje emulzij pa sta ključni njihovo spremljanje in vzdrževanje. Kljub visoki stopnji industrijskega razvoja se nadzor in vzdrževanje hladilno-mazalnih emulzij na obdelovalnih strojih še vedno izvajata ročno. Za nujno potrebno avtomatiziranje in sledenje aktivnosti vseh operacij je v tem magistrskem delu zasnovana nadgradnja prvega prototipa za stalni nadzor hladilno-mazalnih emulzij pri odrezovalnih procesih, ki je sedaj dvignjen na industrijsko raven. Sistem je zasnovan na osnovi serije zaznaval, ki jih sistemsko spremlja mikrokrmilnik. Sistem s krmilnikom je zasnovan tako, da poleg spremljanja omogoča tudi nadzor emulzije z možnostjo korekcije njene koncentracije. Za to je zasnovano in-line preračunavanje dovodnih pretokov koncentrata oz. vode. V delu sta predstavljena sistem in zasnova načina delovanja. Kot eksperimentalni del pa je razviti sistem testiran na obdelovalnem centru Doosan Nx6500. Rezultati dokazujejo, da sistem učinkovito nadzoruje in vzdržuje hladilno-mazalno emulzijo, tako z vidika njene količine kot z vidika koncentracije. In cutting processes, emulsions are a key element in ensuring high performance processes. Monitoring and maintenance of emulsions is crucial for proper functioning of emulsions. Despite the high level of industrial development, the control and maintenance of emulsions on machine tools is still performed manually. As an absolutely necessary automation and tracking of the activities of all operations, this master's thesis is based on the upgrade of the first prototype for the continuous control of emulsions in cutting processes, which is now raised to the industrial level. The system is based on a series of sensors that are monitored systematically by the microcontroller. The system with the controller is designed to allow addition to monitoring also controling of the emulsion with the ability to correct its concentration. For this purpose, an in-line calculation is designed for inlet flows of concentrate or water. The paper presents the system and the design of the operating mode. As an experimental work, however, the developed system is tested on the Doosan Nx6500 Machining Center. The results show that the system effectively monitors and maintains the emulsion, both in terms of volume and concentration. emulzija odrezavanje pH koncentracija električna prevodnost emulsion machining process pH concentration electrical conductivity true false false [I.
