An approach to fixture systems management in machining processes

Abstract

Starting from the premise that the management of fixture systems in the area of machining has been somewhat neglected from the standpoint of its technological development, the work reported on herein focuses on the development of a methodology for the management of these systems. Based on the findings of a survey carried out at companies operating in this sector and on a review of the literature on the subject, both of which confirm this lack, hypotheses are drawn up and supporting data compiled to underpin the development of a systematic, extensive and flexible model. The model, founded on principles of standardization and modularity, basically consists of four main stages: the company's definition/characterization of fixtures management, selection of the type of fixture suitable for the company, rationalization and organization of the area, and the construction of planning and control architectures within the company. We foresee that the formalization of the scientifically-based management support model proposed here will contribute significantly to productive and R&D sectors, computerizing the fixtures management methods used by companies and integrating their managerial philosophies and procedures for machining tools and fixtures

“…he management of fixtures system in machining remain relatively stagnant especially the progress of technology development. This condition governs to the needs of scientifically-based management of model formalization which can give significant contribution to the development of fixture systems [1].…”

“…Gears are used to transmits power and rotational motion between two shafts arranged parallel. The type of the gear used in this design is the straight spur gears, which has the in the following equations to used in the engineering process [1,12].…”

A method for fixturing, scanning, and reorienting an additively manufactured part in preparation for subsequent machining

“…Traditional, dedicated fixtures were introduced as a solution for batch product manufacturing and to counter machine idling time [49]. These fixtures may be effective if the industry produces only a few types of components with a high production rate for a long time period because, once these fixtures have been designed, it can be difficult and expensive to remove or change locating features of the fixture [50].…”
