Quality Control

Design for Machining

  • Prioritize Simplicity: Opt for straightforward geometries to reduce costs and manufacturing complexities.
  • Specify Tolerances Wisely: Overly tight tolerances can increase production costs. Define them based on functional needs.
  • Material Selection: Choose materials that balance performance and machinability. Aluminum and mild steel are economical for prototyping.
  • Include Finishing Allowances: Allow for material removal during surface finishing processes like polishing or anodizing.

Machining Cost Drivers

Category            Description
Material
  • Material Type: Different materials have varying costs and machinability.
  • Material Grade: Higher-grade materials or specialty alloys cost more.
  • Material Wastage: Larger raw material blocks result in higher wastage and costs.
Design Complexity
  • Geometry: Complex shapes and intricate features require more time and advanced setups.
  • Tolerances: Tighter tolerances require slower speeds and more quality checks.
  • Surface Finish: High-quality finishes need additional passes or post-processing.
Volume
  • Batch Size: Smaller batches have higher per-unit costs due to setup overhead.
  • Economies of Scale: Larger runs reduce per-part costs by spreading fixed expenses.
Tooling and Setup
  • Custom Tools: Custom cutting tools or jigs increase upfront costs.
  • Setup Time: Longer setup times for complex parts add to costs.
  • Machine Type: Advanced multi-axis machines are more expensive to operate.
Post-Processing
  • Secondary Operations: Processes like anodizing, polishing, and heat treatment add expense.
  • Inspection and Testing: Advanced quality checks, such as CMM inspections, require time and resources.

CNC Machining Parts
Challange Description Action
Material Challenges Hard-to-machine materials and rapid tool wear. Use high-quality tools, proper coatings, and optimized machining parameters for tough materials.
Complex Designs Intricate geometries and tight tolerances are difficult to achieve. Leverage advanced 5-axis machines and simulation tools to handle intricate geometries.
Programming Errors Mistakes in G-code or inefficient toolpaths lead to scrap or delays. Minimize mistakes by simulating G-code, double-checking toolpaths, and training operators.
Tooling Issues Choosing the right tools and handling tool breakage can be challenging. Select the right tools for the material, monitor wear, and replace tools proactively.
Workholding Securing irregular or soft parts without damage is tricky. Design custom fixtures or soft jaws to secure complex or delicate parts safely.
Heat Management High temperatures can affect accuracy and damage tools. Use cutting fluids, air blasts, and heat-resistant tools to manage high temperatures effectively.
High Costs Expensive machines, tools, and operating costs can strain budgets. Optimize processes, reduce waste, and invest in versatile equipment to improve cost efficiency.
