PORTABLE AUTO HAND SAW

Abstract

Hand saws are often used in manufacturing. However, it is customary to cut something large or small. Furthermore, with the new era there are modern hand saws. One of the problems we often see is that the saw's eye on the saw is easily bent when we push the saw out loud. In addition, when used regularly it can become heated and can cause the material to break down easily. When the material has been damaged then the project to produce the project has become inaccurate. Alternatively, for a machine saw it costs a very high cost. Which can reach hundreds of thousands or tens of thousands. That way, traders need a very high capital to buy it. This is because the material is very expensive and powerful and therefore the price on the machine is very expensive. After that, when the saw machine is damaged it will require very high cost to repair it. Besides that, it also needs to operate its motor by changing its motor oil every month to operate the motor properly so that the motor on the saw machine does not cause damage. The objective of this project was created to design a portable automatic cutting tool, to make safety cutting tools and to analyze personal safety factors while doing cutting work. The method we used to test our project was to use a small piece of iron to cut. It can be done automatically. Then, we test the speed of the motor and calculate how long it takes to cut the material. The results of our project found that this portable automatic cutting tool is suitable for use by adult, workshop workers and small workshop in our tool it is safe to use because because the saw blades that have speed during cutting are protected by the surface side of the project. This reduces the high risk to consumers when cutting work compared to the usual saws we use does not guarantee safety because the saw blades are too exposed to the user. Next, we found that the security features on our device are also safe while making work. The disadvantage of this project is that it still uses manpower to do cutting work. Therefore, there are improvements, among others, is to supply IOT to the project. In this case, the work done only uses a connection to a device such as a telephone to move the work done.
