DESIGN AND DEVELOPMENT OF A FIXTURE FOR VALVE BODIES ON VERTICAL TURNING LATHES (VTLS)

Fixtures are essential components across various industrial applications, designed to securely hold, position, and support workpieces during machining operations to ensure precision and consistency. The process of fixture design and fabrication is intricate, requiring a solid understanding of geometry, dimensional tolerances, operational procedures, and manufacturing methods. This study presents an overview of the 3-2-1 location principle as it applies to the fixture design for complex geometries, alongside a discussion of effective clamping strategies. It also outlines a systematic approach for designing fixtures, with comparisons between modular and dedicated fixture systems, offering practical insights into their implementation in machining valve bodies on VTL machines.
