A Generalised Approach to Design and Layout of GT Machining Cells
This paper deals with two aspects of group technology viz., cell formation and layout of cells. The approach to cell formation is based on workpiece statistics. Some of the workpiece parameters such as their technological features have similarity of occurrence in almost all metal cutting industries. Others could be obtained for the particular industry under consideration. An Interactive Computer program uses this statistical distribution of the parameters and calculates the ratio of different types of machine tools to be employed for machining a particular range of diameter of workpieces. This data along with the production requirements in the particular size range are further used to determine the number of machines of each type to be included in the cell. The cells have been laid out using a specially designed computer algorithm.
