Abstract - Mass production aims at high productivity to
reduce unit cost, and interchange ability to facilitate easy assembly. It could be achieved by the use of jigs. Jigs are provided with tool guiding element such as drill bushes. In this project attempt is made to design drill jig plate. Basically this project will show drill jigs plates that are going to be manufactured and for that analysis too. So for drilling operation at different angle and different position such jigs are made for accurate, precise drill operation in this project. Drill jig increases productivity by eliminating individual positioning, marking and frequent checking. Also jig reduces the repetitive nature required for drilling holes, because the locating, clamping and guiding of the tool is done by the jig itself. Key Words: Design, Manufacturing, Total Deformation Analysis, Maximum Principle Stress, Acrylic material
1. INTRODUCTION Mass production aims at high productivity to reduce unit cost and interchangeability to facilitate easy assembly. This necessitates production devices to increase the rate of manufacture and inspection device to speed-up inspection procedure. The most common jigs are frilling and boring jigs. These jigs are almost same but differ in size, shape and placement of drill bushing. Normally, Boring jigs have larger bushes than drilling jigs. These bushings may also have internal oil grooves to keep the boring bar lubricated. Often, boring jig has more than one bushes to support the boring bar throughout the machining operation. Jigs are further classified as the construction: 1.

Open jigs- It carry out drilling operation in only one side of workpiece. Template jig, plate jig, table jig, sandwich jig are the open jigs Closed jigs- It can carry out work on more than one side of workpiece. Channel jig, box jig, leaf jig are the examples of closed jig

Jigs are special purpose tools which are used to facilitate the production like machining, assembling and inspection operation. The mass production of the workpiece is based on the concept of interchangeability according to which every part produced within an established tolerance. Jigs provide a means of manufacturing interchangeable parts since they establish a relation with predetermined tolerances between the work and the cutting tool. Once the jig is properly setup, any numbers of duplicate parts may be readily produced without additional setup.
2. LITERATURE REVIEW K.rama Subba Reddy [1] This paper shows the static structural and MODAL analysis on DRILL JIG for 3 completely different materials and results are achieved. in line with the results stress is nearly shut for 3 materials however considering deformation is a smaller amount for steel compared with grey forged iron and aluminum alloy. Thus the steel is best material for the producing for such type of the drill jig. R.S. Taufik [2] This paper shows study made in design of jigs and fixtures for hydraulic press machine in manufacturing company. The problems were occurring at industry. It is facing the utilization of hydraulic press machine. When the demand has increased it occurs on the gripping or holding the work piece tightly. The main objective is to give a new design of jigs and fixtures for hydraulic press so as to carry out the gripping problem from existing design. Several new design concepts were given and analyze using ANSYS software. The design parameters were presented are maximum deformation, maximum shear stress, number of contact faces, and maximum holding force. Based on the analysis result, the improvement of new jigs and fixtures design for hydraulic press machine was done. Midhun.R, Vignesh,A [3] From this paper we can make our drilling operation in the work piece as very easy and comfortable and without geometrical error occurring while drilling and it avoids human error also. Sawita D. Dongre, Harshal C. Kuttarmare [4] This paper is about the design and analysis of Jigs and fixture which is used in the manufacturing of chassis bracket of Bajaj car RE60 (passenger car). It shows us analysis of jigs and fixtures from which we find out stress acting on jigs and ISO 9001:2008 Certified Journal
