Methods Of Creating The Cannon

Decent Essays

The main purpose of creating the cannon was to familiarize ourselves with the different machines and techniques that are involved with machining. Throughout the semester, the students are given the freedom to explore and try out the different machines. It was not uncommon to make mistakes but then learn from them. The cannon created a way for the students to experience real world problems and how to fix it on their own.
The cannon was constructed in two parts, the cannon base and the cannon barrel. At the beginning of the semester, we were given an aluminum cylinder, which would become the barrel. The process began with using the Dykem layout fluid to paint the barrel blue, so measurements could be marked. There were several marks made, …show more content…

The barrel can then be inserted into the collet, leaving about only an inch sticking out, and the hand wheel on the side of the lathe can be used to tightened the collet’s grip. To face off the barrel, the cutting tool needs to be utilized. The cutting tool can be installed by inserting it into the holder, with the end facing the Live Center Point. This step is very important to making sure that the tool is centered in height, thus making smooth ends and insuring no damage will be done to the tool. The tool is then flipped so it is facing the barrel. Next turn on the lathe and use the hand wheel to move the tool across the end of the barrel until the reference line is reached. The next step is to center drill the barrel. The Jacob’s chuck should then be inserted into the quill. Next center drill the end the maximum diameter of the ½” center drill. Then change the drill to the 3/8” drill and drill to a depth of 2 1/8 “. The outside diameter should then be turned down to .835”. This is done by loosening the collet chuck and extending the stock to about 5 ½ “ of material is sticking out of the collet. Change the tool holder’s position from the front of the tool post to the side of the tool post. Install the Live Center in the Tailstock Quill and slide the tailstock down to the barrel, inserting the Live Center into the hole of the barrel. Tighten the tailstock. Make sure to use a lot of cutting fluid. Starting from 5 1/8” from the end of the barrel,
