Inverted-U T-Slot Mounting Bracket

Create a one-piece CNC-machined aluminum mounting bracket from a solid rectangular billet. Overall dimensions: Width: 200 mm Height: 200 mm Thickness: 18 mm Material: 6061-T6 aluminum The finished part should have an inverted U-shaped profile when viewed from the front. The upper portion remains solid and forms a horizontal bridge, while a large rectangular/U-shaped opening is machined upward from the bottom edge to create two vertical mounting legs, similar to an inverted U bracket. Vertical mounting legs: Create one elongated vertical mounting slot in each leg. Each slot is 9 mm wide. Each slot is approximately 140 mm long. Slots should have fully rounded semicircular ends with a 4.5 mm radius. Position the two slots symmetrically left-to-right. Slots pass completely through the 18 mm thickness. Keep the slots centered within their respective legs. Upper horizontal mounting slot: At the upper section of the bracket, opposite the open end of the two legs, create one horizontal slot. Slot dimensions: 180 mm long × 9 mm wide. Center the slot horizontally in the 200 mm-wide part, leaving approximately 10 mm of material at each end. The slot runs parallel to the 200 mm width of the bracket. This 9 mm-wide slot should open through the front/top mounting surface. T-slot nut channel: Directly beneath and aligned with the 9 mm × 180 mm horizontal slot, machine a wider internal channel. Channel width: 14 mm. Channel depth: 12 mm. Channel length: 200 mm, extending completely from one side edge of the part to the other. The 14 mm channel should intersect the narrower 9 mm slot to create a T-shaped cross-section. The channel must be open at both ends of the 200 mm-wide part so that T-slot nuts or sliding nuts can be inserted from either side. The intention is for the 9 mm slot to act as the narrow opening while the 14 mm-wide internal channel captures the wider body of the sliding T-slot nut. Machine the entire component from one solid piece of aluminum. Do not model it as bent sheet metal. Keep all major faces flat and perpendicular. Use modest edge chamfers, approximately 0.5-1.0 mm, on exposed exterior edges unless otherwise specified. Internal corners of CNC-machined pockets may have realistic cutter radii.
