PROJECT GUIDE

Prof. Gayatri Abhyankar.1

Belongs to the family of man made or synthetic plastics.

Have excellent mechanical properties and provide an easy replacement of glass.

Wide range of application in engineering, medical and domestic fields

e.g. Aquariums, Sandals, in Furniture, Aircraft windows, Motor bike visors. [1]

INTRODUCTION

ACRYLIC

2

During the drilling process, heat is generated at tool work interface.

Heat depend upon the various factors such as speed, feed and tool geometry.

This heat changes the dimensions of the drilled hole.

It cause the trouble during assembly and poor surface finish. [1]

PROJECT AIM

Investigate the effect of drilling parameters on hole size expansion such as: cutting speed drill point angle sheet size drilling tool material. Make use of Taguchi method to achieve the minimum hole size expansion in drilling of acrylic sheet. 4

DRILLING ACRYLIC TAGUCHI

IrfanKhan,Dheeraj Luthra, MukeshVerma

Drilling Parameter to achieve minimum Hole Expansion by using Taguchi Approach

Taguchi method can successfully verify the optimum cutting parameters[1]

2 DRILLING ACRYLIC TAGUCHI

Irfan Khan, Mukesh Verma , S .S Mann.

( 2012)

Optimization of burr height in drilling of commercial Acrylic sheet using Taguchi method

higher cutting speeds and higher feed rate produces better results with higher tool angle (140 degree)[2].

force and surface roughness in drillingcomposite material using Taguchi analysis and neural network

the feed rate and the drilldiameter are recognized as the most significant factors affecting the thrust force, while the feed rate and spindle speed are seen to make the largest contribution to the surface roughness[3]

Alper Uysal , MirigulAltan&Erhan Altan (June 2011)

Effects of cutting parameters on tool wear in drillingof polymer composite

response of the S/N ratios and ANOVA showedthat cutting speed was the least effective factor while feed was the most significant followed by the drill pointangle for minimum tool wear[4]6

Drilling is to be done on RADIAL DRILLING MACHINE

as shown in Fig.

Analysis approaches like ANOVA is to be used for analysis using TAGUCHI METHOD

A - SPEED

B - TOOL ANGLE

C - TOOL MATERIAL

D -ACRYLIC SHEET SIZE

For analysis Taguchi L 18 orthogonal array is chosen

ANALYSIS

13

The level of the best cutting parameters on the Hole Expansion is to be determine.

Taguchi method can successfully verify the optimum drilling parameters.
