The prompt
Create a highly detailed mechanical bearing housing designed specifically for indexed 4-axis CNC machining. The part starts from a cylindrical billet. Overall dimensions: - Length: 50 mm - Maximum diameter: 40 mm Main features: - Central cylindrical housing with concentric stepped bearing bores. - Front face contains a large circular bearing pocket with multiple concentric steps. - Four equally spaced mounting holes on a bolt circle around the main bore. - Flat machined mounting pad on the top side of the cylinder. - Rectangular pocket on the top mounting pad. - Side rectangular pocket on the right side of the housing. - Through hole crossing the side pocket. - Large rectangular pocket on the opposite side. - Two smaller mounting holes inside that side pocket. - Bottom side contains two support feet separated by a central relief slot. - Long shallow slot running parallel to the rotational axis. - Internal cavities and weight reduction pockets. - Multiple bosses and reinforcing ribs. - Fillets on all transitions. - Chamfers on all external edges. - Realistic manufacturable geometry suitable for CNC milling. Manufacturing constraints: - Designed for indexed 4-axis machining. - Features accessible from A0°, A90°, A180°, and A270° positions. - No undercuts. - No impossible tool access. - Suitable for machining with standard end mills, drills, and boring tools. - Industrial mechanical design similar to gearbox housings, bearing blocks, and small engine crankcase components. Appearance: - Precision machined aluminum 6061-T6. - Engineering prototype. - Functional industrial design. - Realistic mechanical proportions. - Complex but manufacturable geometry. - Professional CAD model. - STEP/CAD-ready mechanical component. Generate a single solid body with engineering-grade dimensions, proper wall thicknesses, realistic bearing seats, and fully manufacturable CNC geometry.
