ABSTRACT

This paper proposes component level optimization of Reconfigurable Machine

Tool by considering its design reconfigurability in configurable machine tool designs.

The potentiality of a configurable system is to be reconfigured and allows to perform

well under different consider loading conditions in different configurations. The

Performance is measured in this paper as machining accuracy, subject to structural

limitations. The ADAMS, Ansys, MATLAB/SIMULINK softwares are used to enable

the component level optimization. In this paper the Configurable Machine tool will be

taken for Optimization process and to achieve the Optimized Components to enable

Reconfigurability in Configurable machine tool components. The algorithm for

Component level optimization is developed in the MATLAB/SIMULINK software.

Keywords: Reconfigurable, ADAMS, MATLAB/SIMULINK#

1. INTRODUCTION

Typically, component or structural level design optimization is carried by means of

considering the structural performance of machine tool and its design based on the

optimization process for a single load case. Predictably the structural performances of

machine tools are stress, mass, deformation, or natural frequencies induced in the machine

tool. Another important aspect is in structural optimization the configurable machine system

is loaded under various conditions. This paper proposes a new design optimization technique

that deals with structural (component level) optimization by considering various different

loading conditions arises in its configuration variations.

The loading conditions are assumed to the structure and it never be applied

simultaneously. The task is not to make the system unresponsive, but to make it

reconfigurable such that the machine tool can deal with the assumed various loading

conditions well. While the robust design is a inactive response to different loading conditions,

M.Sundarraj, T.Raja and M.Karthick


the design for reconfigurability is an active response. The incorporation of this

reconfigurability into structural design can lead to major advantages such as reduced

manufacturing cost, increase sustainability of machine tool.

2. MATERIALS AND METHODS

The figure shows the basic methodology of component level optimization of reconfigurable

machine tool in that a set of structural components for the various configuration are taken into

consideration, these components are analyzed and optimized by means of considering

operating conditions to satisfy different configuration.

The satisfied components are taken individually and not-satisfied components are

considered for optimization based on gradient based optimizer to satisfy the configuration

requirement of reconfigurable machine tool.

3. RESULTS AND DISCUSSION

3.1 Reconfigurable Machine tool Simulation in ADAMS

The Reconfigurable machine tool Model is Simulated in the ADAMS Environment and the

joint and tool forces are calculated, these joint forces are considered as a Structural load for

the Reconfigurable Machine Tool

3.2 Reconfigurable Machine tool Simulation ADAMS model

After getting Results from ADAMS the RMT model is Analysed in Ansys the force from

ADAMS are given into the structure and the Stress Values of the RMT are calculated then the

Variable and Objectives for the Component are selected and design optimization for

reconfigurability is now applied to an RMT.

3.3 Component Level Design requirements

Designing a component that can assist all load cases for structural design. If all load

differences are considered during structural design optimization. And also the component for

different configurations is the attempt for the component level design optimization. The

Reconfigurable Machine Tool designs resulting from optimization in which all different

loading cases are considered at-once is nearly equal. This is cause of the fact of loading

conditions, that the two load cases considered are same images of each other. This structural

design is incapable since the one structural design must adapt all loading conditions.

Elemental Stress values are considered and the Objectives of the Stress component are set in

the Ansys Environment. The results from component level design optimization process are

given below.

CONCLUSION

The structural optimization for reconfigurability in machine tool, all the models from CAD

software CATIA and exported to the ADAMS there the joint forces of the Machine tool will

be analyzed and the Reconfigurable machine tool model are modelled in Ansys based on the

parametric modelling concepts, and the structures, analysis of the Reconfigurable machine

tool is analyzed using the ANSYS software. Based on the results of machine tool system the

optimization of the machine tool components of the desired requirements is identified and the

parameter based optimizations are carried out to get the optimized RMT components for

achieving reconfigurability in machine tool component.

For the automation of Optimization process the Co-simulation is carried between

Ansys/MATLAB SIMULINK, the Algorithm is developed in MATLAB
