This document describes a project to create an automatic lubricating system for a lathe. It monitors the temperature of a cutting tool using a sensor and automatically starts a coolant pump when the temperature increases past a threshold. The coolant is then supplied to the lathe to cool the tool. When the temperature decreases, the pump is automatically switched off. The system circulates coolant to maintain a constant tool temperature while avoiding waste and allowing automatic pump operation based on sensor readings. Potential advantages are constant temperature control, reduced coolant waste, and automatic pump start. A disadvantage is that the closed loop system may be more difficult to maintain.

FABRICATION OF AUTOMATIC
LUBRICATING SYSTEM
Synopsis
A coolant is a fluid which flows through a device to prevent its
overheating, transferring the heat produced by the device to other devices
that use or dissipate it. An ideal coolant has high thermal capacity, low
viscosity, is low-cost, non-toxic, and chemically inert, neither causing nor
promoting corrosion of the cooling system
The most common coolant is water. Its high heat capacity and low
cost makes it a suitable heat-transfer medium. It is usually used with
additives, like corrosion inhibitors and antifreeze. Antifreeze, a solution of a
suitable organic chemical (most often ethylene glycol, diethyl glycol, or
propylene glycol) in water, is used when the water-based coolant has to
withstand temperatures below 0 °C, or when its boiling point has to be
raised.
In our project temperature monitoring system in cutting tool is
monitored by a sensor which is placed in a tool post, when temperature
increased from the specified rate ,automatically pump starts and supply the
coolant to lathe, this circulation system is fully monitored by control system,
when temperature decreases pump will automatically switched off .

Advantage
1) constant temperature is maintain in tool
2) coolant wastage is avoided
3) pump can be start automatically
Disadvantage
1) System is closed loop so maintenance is tough
