An ever increasing demand of manufactured products calls for new manufacturing techniques that are cost effective and efficient. The global population is at an unprecedented rise and anticipating an increased demand for efficient, cheap and durable vehicles as well as automobile parts is nothing but obvious. With a population of over 216 million people, Pakistan stands 5thin the global ranking population wise. The population boom in Pakistan is growing at the rate of about 1.8pc a year, which, when extrapolated to the year 2030, brings out a staggering figure of 240 million people. With little growth in the industrial sector of Pakistan, the local market is forced to import goods for the Pakistani consumer. This presents the businesses and manufacturers all over the world a great opportunity to attract a huge mass of potential buyers in the Pakistani market. However, being a struggling economy, the import culture immensely upsets the balance of imports and exports of Pakistan. The purpose of this research is to promote a cost effective means of manufacturing for the local firms in order to counter the huge influx of imports. Novel techniques will not only promote the culture of research and development in the country, but will also enable the local manufacturers to explore options to fulfil the demand in the local market and provide opportunities for indigenous talent to play their part in the economic development of the nation. Single Point Incremental Forming (SPIF) is a relatively new technique of sheet metal forming. It is a die-less process that shapes the metal sheet in incremental steps for precision and accuracy. The process is relatively simple; a tool path is generated in accordance with the CAD model, the metal sheet is subjected to forming force via computer numeric controlled tool in presence of a lubricant. Once the tool completes its path, the sheet is formed in the desired shape. The materials used in this research are procured from the local market of Pakistan, hence suggesting the automakers over here to try new lines of manufacturing that uses indigenous materials to minimize imports. This study is based on the incremental formability of two materials; Al 5083 and Low Carbon Steel (0.04% Carbon). Both materials are readily available in the local market. The research targets the results of ABAQUS simulations run on the aforementioned materials to experimentally verify them and see their applicability on the practical sid.
