Reducing the Manufacturing Cost by Using Combination Die

Manufacturing cost is the major factor that affects the profit of any industry or any product. Manufacturing Cost involves material, labor, equipment & tooling, quality, maintenance etc. Sheet metal forming is one of the major manufacturing processes and used for most of the products. The Die is the tooling used in the sheet metal forming. The proper design of die is important in sheet metal forming processes. This article discusses how the Combination Die can reduce the manufacturing cost, particularly the labor cost and material handling cost. For this study, a product U Clamp is considered. The Product requires piercing, bending and parting off operations. The Combination Die is designed and fabricated for the product and tested. Data on operation time, material handling time, die fabrication cost are collected, analyzed and discussed.

Productivity is one of the major factors that affect the profit of any industry or any product. In manufacturing industries, the productivity is showing the efficiency of the production unit. It depends on many factors such as technology, machine, method, management, materials etc. In this study, material used is considered and analyzed how it affects the productivity. Productivity is normally expressed as the number of units produced / unit time. Sheet metal forming is one of the major manufacturing processes and used for most of the products. So the selection of material is important for good quality as well as economical production. This article discusses how the material influences the productivity. For this study, a product U Clamp is considered. The materials considered for the study are the aluminum and mild steel. The U clamps are formed by aluminum as well as mild steel by using the same die. Data on operation time, material handling time are collected, analyzed and discussed.

Incremental Sheet Metal Forming

The contemporary sheet metal industry employs forming methods that use a precise die and punch to form components with precise tolerances. In mass production, the high cost of manufacturing dies and punches is absorbed by the number of components formed, whereas this is not the case for low volume production where it increases the manufacturing cost of the products. To overcome the demand for the development of manufacturing technologies that are both agile and meet industrial requirements, an incremental sheet metal forming experiment was carried out on Inconel 718. The incremental sheet metal forming process in the research stage needs to be improved both in terms of accuracy and product quality. The main process parameters involved in the study are incremental depth, rotational speed, and feed rate of the forming tool. Based on the process parameters, experiments are conducted using the Taguchi L9 orthogonal array design and responses such as geometrical accuracy, surface roughness, and thinning are studied. The forming limit and micro-structural study allow us to understand the forming behavior of Inconel 718, which will enhance the applicability of the material.

Practical Recommendations

To determine the accuracy of the readjustable punches for separating operations (perforation + punching out) of sheet-metal forming, the accuracy parameters were analyzed using the random balance method using the method of experiment planning. Analytical dependencies are obtained to determine the values of deviation of the outer and inner contour dimensions of perforated and punched out sheet parts. From the dependencies obtained, it is possible to estimate and predict the value of deviation in the dimensions of the resulting part at any time during the operation of the punch. Practical recommendations on the calculation of the actuating dimensions of the working elements (stamping punch, matrix) of readjustable punches are offered.
