CNC Machining

• 1. Material Costs

  The cost of raw materials (e.g., metals, plastics).

  • Aluminum: ₹150-300/kg ($2-4/kg)
  • Steel: ₹70-150/kg ($1-2/kg)
  • Stainless Steel: ₹200-500/kg ($3-7/kg)

• 2. Machining Time

  The time taken to machine the component, typically measured in hours. Factors Influencing Time: Complexity, size, and type of operation (milling, turning).

  • CNC Machining: ₹1,200-3,000/hour ($15-40/hour)

• 3. Tooling Costs

  The cost of tools used for machining (end mills, drills, inserts).

  • Tooling costs: ₹10,000-50,000 ($130-650)

• 4. Setup Costs

  Costs associated with setting up the CNC machine for production.

  • Setup: ₹2,000-10,000 ($30-130)

• 5. Labor Costs

  Wages for operators and engineers involved in the machining process.

  • Operator: ₹300-800/hour ($4-10/hour)
  • Engineer: ₹800-2,000/hour ($10-30/hour)

• 6. Overhead Costs

  Indirect costs such as electricity, maintenance, rent, and administration. Typical Rates: Generally calculated as a percentage of total costs, usually around 20-30%.

• 7. Quality Control Costs

  Costs associated with inspections, testing, and quality assurance.

  • Quality inspection: ₹1,000-5,000 ($15-70) per batch

• 8. Post-Processing Costs

  Additional processes such as finishing, coating, or assembly.

  • Finishing (e.g., anodizing, painting): ₹20-100/kg ($0.3-1.5/kg)

• 9. Packaging Costs

  Costs for packaging materials and methods.

  • Packaging: ₹50-200 ($0.7-3) per component

• 10. Delivery Costs

  Transportation costs to deliver the finished product.

  • Delivery: ₹500-2,000 ($7-30) per shipment
