Mild Steel (MS) is the most widely used material for machine component manufacturing. In Bangladesh, the small and medium scale companies occupy the major portion of the country’s machine or machine components manufacturing using MS and other materials. Most of these companies do not have enough engineering skills on adequate and economical machining processes design. This paper demonstrates an easiest real life experimental methodology of determining optimal cutting regimes for locally available MS using homemade cutting tools in the workshop environment. As the application of this experimental methodology the authors have also displayed preliminary results of optimization of cutting regimes (speed, feed, and depth of cut) for machining locally available Mild Steel using high speed steel cutting tool (homemade). The results have witnessed that the user-friendly methodology can be used in any metal machining company of any sizes. The significance of this paper is to widely publicise the methodology which is highly benefitable for metal machining industries.
