edm fixture 3d model

Design a precise mechanical fixture for EDM wire cutting of a small cylindrical tube. The tube has an outer diameter of 5 mm and an inner diameter of 1 mm. The fixture must securely hold the tube and allow accurate indexing for machining four flat surfaces (facets) around the circumference. Each facet should be rotated exactly 90 degrees relative to the previous one, resulting in four evenly spaced cuts. Key requirements: High-precision clamping system suitable for delicate, small-diameter tubing Accurate 90-degree indexing mechanism (manual or integrated rotary indexing feature) Stability during EDM wire cutting to prevent vibration or deformation Accessibility for EDM wire path without obstruction Compact and manufacturable design Material suitable for EDM environment (e.g., non-corrosive, rigid metal) Optional features: Alignment guides for repeatability Fine adjustment mechanism for centering the tube Markings or detents for indexing positions The output should be a detailed
