Machining Time Reduction of Cylinder Holding Plate Using U Drill

Machining optimization has an inevitable role in contemporary operation of CNC and non-conventional machining process. The objective of this project is the reduction of time of machining of the cylinder holding plate. The cylinder holding plate is used in the earth movers for holding the hydraulic cylinders. The holding plate is used to make the movements of the buckets in the front of the earth movers. The cylinder holding plate is made by the help of VMC machines. This can be done with the help of mild steel plate. The profile of the cylinder holding plate is cut from the mild steel plate. Then the machining process is done with the help of drilling tool and milling cutters. The first process of the machining is drilling with a diameter of 22mm. There are 8 drill of 22 mm is used in the machining process of the cylinder holding plate. To make the drill of 22mm diameter need to put a drill using a 3 drill bits. The first drill bit is through hole drill, after that the pilot drill is used to make the drill more bigger than the previous drill, and then using the drill bit of 22mm. This time taken for making the drill of 22 mm in premachining process is 10min and in the post machining process is 30 min. The total time taken for making a 8 drills of ø22mm is 40 min. To reduce the machining time of drilling we using the tool called U drill of 22 mm. This tool will reduce the time of machining of drilling up to 50%. By changing the tool we reduce the 50% of time of machining.
