-Abstract
This work is carried out to design and analyse an assembly fixture for the column used in a CNC horizontal
machining centre. Here the efforts are made to reduce overall set up time required for assembling the column in the
machine. The objective was to study the existing mechanism and identifying critical parameters which influence the
design of the assembly fixture. In this process, various new concepts were generated and comparison is made between
them. A systematic new product design approach has been followed for generating new assembly fixture concepts. In this
process, various tools & techniques such as Concept Classification Tree, Concept Combination Table and Concept
Scoring Matrix are used. 4 different assembly fixture concepts were generated and best concept is selected with help of
above stated tools. System design, detail design of the selected concept was carried out and 3D modelling was done
using PTC Creo Elements Direct Modelling 17.0. Two dimensional manufacturing drawing of the fixture subcomponents were generated in the last stage of design process.
