DEVELOPMENT A GROUP FIXTURE SYSTEMS FOR MACHINING CENTERS

Abstract

A special problem in the construction of the fixture is a limited workspace of machines and large overall dimensions of the workpiece. This problem is especiall pronounced during machining in more work plane at machining centers. In these cases, recognize fixture systems can not be applied. The dedicated fixture systems, in parinciple, could satisfay the basic function but have a number of disadvantages in terms of high costs and low flexibility, especially when it comes to machining process of geometrical and technological similar workpiece. This paper presents a model of group fixture system that allows cutting process with different cutting tools in four work plane. Construction of group fixture system has been optimized from the aspect the minimum required workspace of machines. This very complex problem of design was solving through optimization phase of a large number of conceptual solutions, phases of numerical analysis of structures and phase of calculate making errors.
