Abstract

This project proposes is to design and develop the round bar motorize jig for the rotary abrasive water jet (RAWJ) process. This technology is one of the hybrid technologies that been studied throughout the years. RAWJ is based on machining which applied the abrasive waterjet as the cutting medium such as in the conventional lathe that turning the specimen with the chuck mechanism and cutting tool is the cutting medium. The motorize jig is designed through the Solid-Work design software where the final conceptual design is selected based of the Pugh method that consist of screening and scoring concept. Then, the development and fabrication of the motorize jig which have dimension approximately about 510 x 340 x 150 mm is undergo several processes such as cutting process, squaring process, drilling process, tapping process, milling process, slotting process, profiling process, pocketing process. The development of the motorize jig have slightly different with the other type of abrasive waterjet turning (AWJT) jig which the replacement of the 3-jaw chuck with the collet mechanism which have lower runout error, it is designed to be portable motorize jig and the length of the specimen to be process is adjustable up to 200mm. The developed motorize jig is then validate through several standard with different categories such are the International Standard Organization (ISO) 10816 standard for the vibration measurement test, the American Petroleum Institute (API) standard which are API 617 (compressors) and API 612 (steam turbines) for the collet runout of the unload specimen and the ISO 7919 for the overhang and tailstock installation for the loading specimen. Project has been conducted to determine the motorize jig feasibility upon the profiling process and the test were run for two different specimen rotation on the solid mild steel with 16mm in diameter. The result of the 10mm length of the specimen cutting surface with abrasive waterjet pressure at 380MPa is observed by using of the optical microscope and the results show that the waviness of the specimen cutting surface for the anti-clockwise flow direction seen more finer than the clockwise flow direction.
