“…After implementing a 3D design of the fixture a NC program simulation including an interference check is carried out by installing the model into the Computer Aided Manufacturing (CAM) system [47]. The procedure of finding an appropriate fixture configuration can also be optimized by the use of object/rule based automated fixture design systems [48], [49], [50]. Such a system is calculating locating, supporting, clamping planes and points from geometric and textual information.…”

“…The search for flexible clamping solutions has been a prior task over the last decades, 1,2 as the fixturing process is a critical factor with influence on the machining accuracy of high-precision parts. 3 Among the different machining cases, the floor-milling process of thin parts is one of the most critical operation due to the thickness and roughness quality tolerances required in the industry.…”

“…There are variant and generative systems in automatic fixture generation also. Nee et al [5] proposed a variant fixture design system based on a feature-based classification scheme for fixtures. A workpiece belonging to the same part family is assumed to have similar machining features and/or requires similar operation sequences and setups.…”

Fixturing is the most commonly used manufacturing constraint in setup planning. The computer-aided fixture design technique is being rapidly developed to reduce the lead-time involved in manufacturing planning. An automated fixture configuration design system has been developed to select modular fixture components automatically and place them in position with satisfactory assembly relationships. In this paper, an automated fixture generation system for prismatic components is presented. Sequential steps for automatic fixture layout planning for machining setups, focusing on determining the most suitable locating and clamping positions in accordance with the 3-2-1 configuration, considering geometrical and dimensional constraints are presented. A software has been developed which takes two-dimensional-manufacturing drawings of the prismatic components as input and generates fixture design automatically. The modularity concept is incorporated in the developed software application and enables locating positions to be as wide apart as possible. The clamping positions are obtained directly opposite to the respective locators as far as possible. The software is tested successfully with numerous examples of prismatic parts involving similar design characteristics.
