INTRODUCTION
Development of computer numerically controlled (CNC) machines is an outstanding contribution to the manufacturing industries. It has made possible the automation of the machining processes with flexibility to handle small to medium batch quantities in part production.
Initially, the CNC technology was applied on basic metal cutting machines like lathes,milling machines, etc. Later, to increase the flexibility of the machines in handling a variety of components and to finish them in a single set-up on the same machine, CNC machine capable of perfoming multiple operation were developed. To start with, this concept was applied to develop a CNC machining centre for machining prismatic components combining operation like milling, drilling, boring and tapping. Further, the concept of multi-operation was also extended for machining cylindrical components which led to the development of turning centres.
