The objective of Automatic Saw Cutting project is to cut the metals and woods automatically with out man power.


Automatic Saw Cutting project is very useful in the industrial companies. In industrial companies there is need to cut the metals and woods to different shape. By using man power it takes many times, and also accuracy may be low. By using this project cutting operation is preformatted automatically. So it saves the time as well as reduces the man power. The accuracy also achieved in this project.

This project is designed with microcontroller, Real time clock, Relay driver circuit along with relays, Keypad and Mechanical arrangement.

Real time clock is the special type to IC integrated circuit used to generate real timing signal. It is generally called as RTC. Battery is in build in this IC. Even though power is switched OFF, it can maintain the timing signal. RTC sends the timing signal to microcontroller.

Here the microcontroller may Atmel or PIC both are flash type reprogrammable microcontroller in which we have already programmed. The set of keys in the keypad is used to set the time of operation.

For an example if you want to cut the material for an hour the timing is set in the microcontroller through the key bad. The microcontroller receives the timing signal from RTC, and activates the relay driver circuit for that particular time period.

The relay output is directly connected mechanical arrangement. This mechanical arrangement is designed to be fit the different hack saw such as slanting teeth, sharp teeth etc.

So the cutting operation is performed for that particular time period. At the end of the setting time, microcontrollers turn OFF the relay so the cutting operation is stopped. Through this way cutting operation is performed automatically
