Formulation of a customer-oriented product and determination of optimum design parameters using response surface methodology

The development of a product demands numbers of consideration and customer-based product dominates the present market. This study aims to formulate a customer-oriented product and investigate the optimum design parameters level for this formulation. The customer-oriented product named 'CNC PCB Plotter' – is proposed as a handy tool to make a single PCB within a short time and cost. In the sophisticated art of product design, the desires of the customer should be the only constraint. With this in mind, an organized approach is conducted to formulate the product. Suitable design parameters with their optimum ranges provide the sustainability of the product. Response Surface Methodology (RSM) is applied to determine the optimum level of design parameters. A ۲-level ۳ factorial Central Composite Design (CCD) provides the experimental trails. This research involves the customer demand and specifies the design parameter, such as cutting speed, feed rate, and depth of cut. The average dimensional accuracy is taken as a response and found ۰.۰۲۷ µm with a combination of cutting speed ۵۳.۶۷۶ m/min, feed rate ۲۵۳.۲۷۲ mm/min, and depth of cut ۰.۴۹.mm, which is found to be the optimum value.
