Desenvolvimento de um protótipo para controle de nível de óleo solúvel com envio da informação por meio de IoT

Abstract

Soluble oil or cutting fluid is an important element for the machining process in CNC. Its main purposes include cooling the material removal region, lubricating the friction surface and protecting the machine and machined parts from corrosion and oxidation. Monitoring the level of the cutting fluid in its reservoir is of great importance to ensure that there is no shortage. This work aimed to develop a prototype that automates the supply, measures the reservoir level and transmits this information using IoT resources and protocols. To achieve these objectives, a system was developed that integrates a laser sensor to continuously monitor the fluid level, an electro-valve responsible for automatically opening and closing the supply. And the management of data acquisition and processing is performed by an ESP32 microcontroller, withtransmission via Wi-Fi. This prototype was successfully installed in a machine (CNC), including customized fixing devices for the laser sensor and the electro-valve, in addition to a plastic box to house the microcontroller. This system demonstrated effectiveness and reliability, validating the proposed objectives and offering a practical and modern solution for monitoring and controlling cutting fluid in machining environments.
