High-volume manufacturing benefits from reduced unit costs, where initial investments are offset by economies of scale. - Payback Period Calculation:
Calculating the payback period—how long it takes to recoup the investment through increased efficiency—helps determine the financial viability of a CNC machine purchase. - In-House CNC Machining vs. Outsourcing:
Businesses must decide whether to invest in in-house CNC capabilities for greater control and faster turnaround, or outsource machining tasks to reduce capital expenditure.
6. How to Reduce CNC Machining Costs
CNC machining can be a costly endeavor, especially for low-volume production or custom parts.
Imidlertid, by optimizing your design, materialevalg, og bearbejdningsprocesser, you can significantly reduce CNC machining costs without sacrificing quality.
Here are some strategies to help you stay within budget:
Design optimering
Optimizing your part design can have a significant impact on the overall CNC machining cost.
When designing parts for CNC machining, the goal is to minimize unnecessary complexities and ensure the part can be efficiently manufactured.
- Check Hole Sizes and Profiles: Ensure that features such as slots, huller, and threads are designed to be compatible with standard cutting tools.
Custom tools for non-standard sizes can add considerable cost. By designing around standard sizes and profiles, you can avoid the high costs of custom tooling. - Avoid Deep Cavities and Thin Walls: Deep cavities and parts with thin walls are difficult to machine accurately and often lead to part failures or scrappage.
Avoiding these design features can help reduce machining time and improve the likelihood of successful production. - Minimize Tight Tolerances: Parts requiring tight tolerances are often more expensive to produce due to the increased complexity and need for higher precision.
Hvor det er muligt, avoid specifying unnecessary tight tolerances. Use shared reference points or datum points to reduce the number of tolerances and simplify the inspection process. - Break Complex Parts into Simpler Sections: If the part is too complicated, consider breaking it into smaller, easier-to-machine sections that can be assembled afterward.
This reduces the overall complexity of the machining process, cuts down setup time, and maximizes cutting efficiency.
Review Material Selection
The material chosen for your part plays a crucial role in the machining cost. Different materials have varying levels of machinability, which affects both machine time and overall cost.
Ved valg af materialer, overveje følgende faktorer:
- Materielle omkostninger: Nogle materialer, such as titanium or specialized alloys, can significantly increase the cost of machining.
If possible, opt for less expensive materials that meet the functional requirements of your part. - Bearbejdningsevne: Some materials are more difficult to machine than others, requiring longer machining times and more tool wear.
Materials with better machinability (like aluminum) are more cost-effective in CNC machining processes.
Outsource to Low-Cost Regions
Outsourcing CNC machining projects to regions with lower labor costs can be a highly effective strategy to reduce overall expenses.
While CNC machining services in developed countries, such as the U.S. or Europe, can be expensive due to higher labor costs, outsourcing to countries like China offers substantial savings.
- Price in Developed Countries: In countries with higher living standards, CNC machining rates for multi-axis machines typically range from $75 til $120 i timen.
For 3-axis machines, rates usually range from $35 til $40 i timen. - Price in Asian Countries: Chinese CNC machining companies, såsom DENNE, offer highly competitive pricing,
with rates as low as $8 til $10 per hour for 3-axis machines and $30 per hour for multi-axis machines. These companies also maintain high standards of quality assurance.
Consider Automation and Lean Practices
Integrating automation and lean manufacturing principles can help further reduce CNC machining costs.
Automation can streamline the production process, reducing the time spent on manual labor and improving the efficiency of machine operation.
Desuden, adopting lean principles can minimize waste, reduce machine downtime, and optimize production schedules, resulterer i samlede omkostningsbesparelser.
Consolidate Orders for High-Volume Production
If you are working with a CNC machine shop on multiple orders, consolidating your orders into a high-volume batch can reduce the cost per unit.
High-volume production typically allows for more efficient use of the machine and reduces setup times.
This results in lower overall manufacturing costs per part, which can be particularly beneficial for companies that plan to produce large quantities.
