THE MACHINE TOOL RIGIDITY FACTOR IN MODELLING A COMPUTERISED MACHINABILITY DATA BASE SYSTEM

摘要

Modal analysis is a powerful tool in machine tool rigidity studies. The results of these studies have rarely been considered by research workers when modelling mathematically the extended Taylor tool life equation. The authors used the rigidity factor in these equations and the computerised machinability data base system (CMDBS) developed at the University contains this novel concept. The optimum cutting data obtained thereby for turning operations was found to be very reasonable. The use of a fully comprehensive CMDBS in CNC machine tools is one of the essential steps towards the goal of computer integrated manufacturing.
