The end of this paper was to clarify the simulation process of named factors in the interface of CAD/ CAM system CATIA. This process is important to enter the process of manufacturing of colourful perfection engineering factors of complex shape designed for the requirements of automotive and aerospace diligence. This project involves Analysis of the combination tool to perform desire operation. This combination tool can perform two operation which End milling, Reaming, this can be done in such manner that the lower part that is end mill will remove the material from previously drilled hole then the second stage of operation commence in which the reamer will finish off the small tiny particle in order to achieve desired flawless finish.
Introduction
I. INTRODUCTION
CATIA V5 is one of the advanced CAD/ CAM systems, because in addition to modelling and offers specialized attestation and product assembly accoutrements, assemblies and design areas of thin essence wastes, different strength analysis, as well as pretend turning, mulling moulds, drillingetc. 3D model created from CAD part of CATIA is also fitted to a process of simulation, where is generated NC law for the colorful control systems, CNC machining centres [1]. In moment’s CIM terrain and competition age, the main attention of manufacturer is a cost reduction. When it isn't possible to reduce the fixed cost, it's necessary to concentrate on variable cost like electricity, slice fluids. The design of the combination tool has been made on catia software and later the analysis of the tool is done on same. The analyses of different forces acting on the tool were studied. CNC milling machines are substantially used for perfection and further productivity. This requires a transfer of high speed as well as the high slice speed of machine tools [2].
II. LITERATURE REVIEW
From this paper we get to know that In Artificial world CNC machines are dominating because of its protean form of robotization. The structural accoutrements used in a machine tool play a decisive part in productivity, delicacy and face finish of the corridor manufactured in it [3].
A static analysis calculates the goods of steady lading on a structure, while ignoring indolence and damping goods, similar as those caused by time- varying loads. A static analysis can, still, include steady indolence loads ( similar as graveness and rotational haste), and time varying loads that can be approached as static original Stationary analysis is used to determine the deportations, stresses, strains, and forces in structures or factors caused by loads that don't induce significant indolence and damping goods [4].
III. PROBLEM STATEMENT
It is observed that in the company the two operation were done in the CNC machine which takes time to change the tool, Hence, increases the cycle time of the CNC machine.

The Maximum von Mises stress is 2.25e+009 Nm2
The Minimum von Mises stress is 12.9 Nm2
Conclusion
Through analysing the design of the tool it is concluded that the prototype model of the tool in which the analysis were implemented has ability to take enough load. Although, It is not fully prepared for the mass production still the further analysis needed to be done.
