Development and Experimental Investigations into Multi Jet Rotary Nanofinishing Process

Abstract

Metallic dies and moulds play a crucial role in manufacturing industries, particularly in industries that produce a large number of identical parts or products. Metallic dies and moulds in manufacturing industries are designed to produce high-precision parts and products that are consistent in quality and dimension. This is especially important in industries where even small deviations in dimensions or specifications can cause product failure or other issues. Increased efficiency using metallic dies and moulds in manufacturing can help to increase efficiency and productivity. The use of automated systems and machines that are designed to work with dies and moulds can speed up the production process and reduce the need for manual labor. The use of metallic dies and moulds can be cost-effective for manufacturing industries in the long run. While the initial investment in the tooling can be high, the cost per part or product can be significantly reduced as a result of the increased efficiency and precision. Most of the automated techniques used for surface polishing of open dies and moulds are still the slowest one with the polishing time in certain cases constitute the significant percentage of overall die manufacturing time. The advances in die polishing technologies have helped to minimize these problems to certain extent and have enabled achievement of better surface finishing. But these processes still have scope for improvements to make them more efficient in the present context of demand for higher manufacturing productivity and the stringent requirement of product quality. Many researchers have proposed various non-conventional post processing techniques such as chemical polishing (CP) and electropolishing (EP), to improve the surface quality. Some have even used integrated techniques combining with electrical polishing (EP), mechanical polishing (MP) and ultrasonic methods, or use of abrasive jet polishing (AJP) and magnetorheological finishing process (MRF) to improve the surface quality.
