Manufacturing Specification for 9 Gold Sluice Boxes

1. Material Specifications

• Material: Aluminum Chequered Sheet (Tread Plate)
• Standard Sheet Dimensions: 2.44 m (length) × 1.22 m (width)

2. Cutting Strategy

To optimize material usage and minimize waste, the cutting process follows a specific pattern for each standard sheet.

Cutting Procedure per Sheet

1. Length Cut: Cut the 2.44 m length into two equal halves.
   • Resulting Length: 1.22 m (122 cm) per piece.
2. Width Cut: Cut the 1.22 m width into two distinct sections.
   • Primary Section: 85 cm (Used for the main body of the sluice).
   • Secondary Section: ~37 cm (Leftover piece).

Resulting Component Dimensions

• Main Plate: 2.44 m x 85 cm
• Side Plates: Derived from the remaining ~37 cm strip or adjusted from the main plate depending on the final assembly geometry. Correction based on constraint: The prompt specifies the final sluice length is 2.44 m and width is 85 cm. This implies the entire 2.44 m x 85 cm strip is the base.

Let us re-evaluate the geometry based on the final constraint:

• Final Sluice Length: 2.44 m (244 cm)
• Final Sluice Inside Width: 59 cm
• Side Height: 13 cm (vertical)

Material Yield Calculation

• Base Plate: Requires a sheet of 244 cm x 59 cm.
• Side Plates: Requires four strips of 244 cm x 13 cm (two long sides, two short ends? No, a 3-sided sluice usually has two long sides and a bottom, or one long bottom and two sides).
  • Standard 3-sided box: Bottom + 2 Long Sides.
  • Bottom Area: 244 cm x 59 cm.
  • Side Area (2 pieces): 244 cm x 13 cm each.

Optimization of Standard Sheet (244 cm x 122 cm):

1. Cut the 122 cm width into 59 cm and 63 cm.
2. The 59 cm strip becomes the Bottom.
3. The 63 cm strip can be cut into two 13 cm sides (13+13=26) with significant waste, or more likely:
   • The prompt states: “dividing 122 cm width… into one piece of 85 cm and remaining piece to be approximately 37 cm”.
   • This implies the Base Width is 85 cm? No, it says “Inside width must be 59 cm”.
   • If the inside width is 59 cm and side height is 13 cm, the Total External Width is 59 + 13 + 13 = 85 cm.
   • Therefore, the Base Plate Width is 85 cm.

Revised Cutting Plan per Sheet:

1. Cut Length: Keep at 2.44 m.
2. Cut Width:
   • Strip 1: 85 cm (This is the Total Width of the assembled sluice).
   • Strip 2: ~37 cm (Waste/Offcut).

Fabrication from the 85 cm Strip:

The 85 cm wide strip is folded or welded to create the 3-sided box.

• Center Section (Bottom): 59 cm wide.
• Two Side Sections: 13 cm high each.
• Check: 13 cm (Side) + 59 cm (Bottom) + 13 cm (Side) = 85 cm.

This confirms that one standard sheet (2.44 m x 1.22 m) yields one complete sluice body (bottom + two sides) if the sides are formed by bending/folding the 85 cm strip, or welding separate plates. Given “aluminum chequered sheet”, bending is efficient.

3. Manufacturing Steps

Step 1: Sheet Preparation

• Take one standard aluminum chequered sheet (2.44 m x 1.22 m).
• Cut the length to 2.44 m (if not already).
• Cut the width into two pieces:
  • Piece A: 85 cm width.
  • Piece B: ~37 cm width (Discard or use for other purposes).

Step 2: Forming the Sluice Body (Piece A)

The 85 cm wide strip is transformed into a 3-sided channel.

• Inside Width: 59 cm (Center section).
• Side Heights: 13 cm (Left and right flanges).
• Method:
  1. Mark lines at 13 cm from each edge of the 85 cm width.
  2. Bend or fold the sides up along these lines.
  3. Alternatively, cut the 85 cm strip into three separate plates (59 cm bottom, two 13 cm sides) and weld them. Bending is preferred for integrity.

Step 3: Assembly

• Ensure the inside width is strictly 59 cm.
• Ensure the vertical side height is 13 cm.
• Seal all joints to prevent water leakage.
