I want ppt on automatic pvc pipe cutting machine for project purpose.

A pipecutter is a type of tool used by plumbers to cut pipe. Besides producing a clean cut, the tool is often a faster, cleaner, and more convenient way of cutting pipe than using a hacksaw, although this depends on the metal of the pipe.
There are two types of pipe cutters. Plastic tubing cutters, which really look much like a pair of pruning shears, may be used for thinner pipes and tubes, such as sprinkler pipe. For use on thicker pipes, there is a pipecutter with a sharp wheel and adjustable jaw grips. These are used by rotating it around the pipe and repeatedly tightening it until it cuts all of the way through.
Pipecutters vs. hacksaws
Hacksaws will cut nearly any size pipe made out of metals and plastics. Pipecutters, on the other hand, are more limited. In the situations where they work, they are generally accepted to leave cleaner cuts on the outer surface of the tube. The cut can leave a burr around the inside of the tube. This burr should be cleaned or reamed when cutting electrical conduit to prevent stripping of the insulating coating from the wires.

Cutting the tools or the materials of finite length by manually will not yield a good result. So we have designed and developed the system which will cut the material automatically of finite length according to our requirements. We mainly concentrate on PVC cutting Machine for which we have designed the system.

The block diagram consists of the following components such as IR transmitter, IR receiver, LCD display, Microcontroller, keypad, Relay driver circuit, relay, and the cutter.

The IR sensor is placed on the PVC machine where the final output PVC comes out of the machine. The IR sensor senses the Length of the PVC and the corresponding length at that particular instant is displayed.

The target length is fixed in the keypad. The IR sensor which is placed near the product senses and sends the electrical output signal to Microcontroller. The current length is continuously displayed on the display.

Now the Microcontroller compares the sensed signal and the target value and sends the corresponding signal to the relay driver circuit .If both the sensed value length the microcontroller delivers the corresponding signal to the relay driver circuit.

The relay driver circuit enables the relay which in turn connected to the cutter. Now, the cutting tool cuts the PVC of finite Target length, what we desired.

According to the length what we design the cutting tool, cuts the PVC automatically. This type of cutting machine can be used anywhere, where we find the application of cutting the materials of finite length automatically .it results in very accurate value. This is applicable to all type of industries
