Abstract

Conventional machines have a lot of problems, particularly in terms of tool life, productivity, and surface finishing. Abrasive Water Jet Turn (AWJT) is an alternative to conventional machining. AWJT is a type of unconventional machining process that uses a high-pressure water jet that is mixed together with abrasive particles. It is very suitable for the hardest material and cylindrical workpieces. Inconel 718 Alloy is the material that will be used for this project. Inconel 718 alloy is known as the hardest material and is very difficult to machine using conventional methods. Inconel 718 Alloy has an excellent combination of corrosion resistance, oxidation resistance and creep resistance. This type of material is usually found in the aircraft industry. The preparation, experimentation, data collection, and data analysis are four stages in the completion of this project. 8 samples with a diameter of 16 mm and a length of 50 mm will be machined using the AWJT machine. A full factorial design is involved in this project to ensure that the experiment is carried out in a systematic and efficient manner. All the data is collected by using a surface roughness machine and a roundness tester machine. The data is analyzed by using ANOVA and to identify the significant effect of the parameter is optimized or not.
