Abstract

The objective of the project is to provide the lubricant on the heading machine.

Scope:

This project is used in the metals grinding machine, such as drilling machine, lathe.

When grinding the metals, the grinding tools getting head due to the head the grinding tool may be damaged. By using this project the lubricants automatically sprayed on the tools in order to reduce the head.

Brief methodology:

This project is designed with Microcontroller, Amplifier, ADC, Transducer sensor, Relay driver circuit and Coolant Pump.

Temperature sensor is the one type of transducer fixed in the grinding spindle. This transducer changes the resistance value in responds to the temperature. So it provides the different voltage signal depends on the temperature then the signals are fed into amplifier circuit.

The amplifier circuit is constructed with operational amplifier. It is act as power amplifier to amplify the weak signal from the transducer. Then amplified signal is given to ADC.

ADC is nothing but analog to digital converter which converts input analog signal into corresponding digital signal. The converted digital signal is given to microcontroller.

Here the microcontroller may be Atmel or PIC both are flash type reprogrammable microcontroller, in which we have already programmed. So it received the signal from the ADC and compared with stored value.

It temperature is higher with stored value; the microcontroller activates the relay driver circuits. The relay output is directly connected coolant pump. Now the coolant pump is operated and lubricant is provided on the grinding tools in order to reduce the head
