A Used Manual To Reduce Costs By 40% In Machining Titanium Alloy Aerospace Parts With CNC
| Optimization Dimensions | Traditional Method (High Cost) | LS Precision Solution (40% Cost Reduction) | Key Points at a Glance |
|---|---|---|---|
| 1. Tool Strategy | Using general-purpose coated inserts results in short tool life and conservative parameters. | Using specialized titanium alloy inserts with PCVD coatings or ultra-fine-grain substrates, combined with high-pressure coolant (HPC) technology | Tool life is increased by 300%. High-pressure cooling effectively breaks chips and reduces cutting temperatures, which is the key to success. |
| 2. Cutting Parameters | Using conservative parameters can lead to tool chipping and poor surface quality. | Aggressive, data-driven parameter optimization: Experimentation is used to determine the optimal combination of high linear speed (Vc) and high feed (f), rather than simply pursuing low parameters. | “Slow and steady” can be more expensive. Scientifically improving parameters can significantly shorten cycle time. |
| 3. Programming and Path | Simple constant-height cutting results in frequent idle travel and unstable cutting loads. | Intelligent CAM Programming: Utilizing strategies such as trochoidal milling and dynamic milling maintains a constant cutting load, reducing idle travel and tool impact. | This reduces machining time by 35%. Smoother cutting = higher efficiency + better quality + longer tool life. |
| 4. Fixtures and Setup | Multiple setups lead to accumulated positioning errors and lengthy tool life. | Integrated fixture design and multi-process consolidation: Designing specialized composite fixtures allows multi-faceted machining in a single setup, reducing setup times and machine time. | This reduces setup time by 60% while improving geometric and positional tolerance accuracy. |
| 5. Quality Control | Post-process offline inspection prevents problems from being discovered too late. | On-machine measurement (CMM) and process control: Probe measurement is performed directly on the machine after key processes, compensating for tool wear in real time and eliminating batch scrap. | This reduces the scrap rate from 3% to below 0.5%, saving significant rework and material costs. |
| 6. Overall Collaboration | Different departments (programming, machine operation, quality inspection) work in silos. | Establish a closed digital manufacturing loop: Seamlessly transfer data from CAD/CAM to CNC, record and analyze each part’s machining data for continuous optimization. | Data is the new gold. Data-driven decisions make the optimization process sustainable and replicable. |
A 40% savings isn’t magic; it’s the product of systematic engineering.
It is the product of:
- Technological advancement (specialized tooling, high-pressure coolant)

Case Study: Reduction Of A Flap Guide Component Cost By 40%: The Whole Process
Here, I’d like to use a live project that we completed recently as an example and describe how we brought significant cost savings and efficiency gains to our client by leveraging technological innovation.
This project was a titanium alloy flap guide component of a certain passenger aircraft. As we all know, such a part has a complex shape, is difficult to machine, and requires extremely high quality, so cost control is always a concern.
1. Initially, there were tremendous challenges:
Low Machining Efficiency: Traditional processes were conservative, with a machining time of up to 22 hours per part.
High Tool Costs: Frequent tool replacement due to the severe wear of titanium alloys was expensive.
Quality Risks: It is not difficult for incorrect cutting heat control to bring about work hardening on the surface of the workpiece, with a potential for microcracks.
2. Our Technical Solution:
Faced with this challenge, my team did not simply optimize certain parameters; instead, we reshaped the entire machining process.
“Digital First-Part” Simulation Optimization: Before generating the final machining program, we employed advanced cutting physics simulation software. As a “digital pre-machining” of the part, we precisely simulated the forces, temperatures, and vibrations of each cut. This allowed us to scientifically and significantly increase cutting parameters, more than doubling roughing efficiency and completely eliminating tool breakage risk.
“Follow-the-flow” toolpath: We substituted the previous “brute-force” approach with an adaptive dynamic milling method. The tool now moves continuously and smoothly through the cuts without altering the load. The benefits were immediate: cutting temperatures were controlled, chips were evacuated smoothly, and tool life increased by 50%.
“Unifying the Parts into One” Turn-Mill Solution: We utilized the five-axis turn-mill center capabilities to their fullest. With a multi-axis sync program that I wrote myself, we completed all turning, milling, drilling, and tapping operations in one setup. This not only eliminated multiple setup errors and saved auxiliary time, but more importantly, allowed for very high positional accuracy between all of the features.
3. Direct Value for You:
Upon implementing this combined approach, the final outcomes were impressive:
Overall costs were reduced by 40%, well beyond customer expectations.
The per-part process time was reduced from 22 hours to 11 hours, doubling the production capability.
Tooling expenses were reduced by 35%.
Most importantly, the process stability was extremely high, with 100% product quality and no scrap.
This sample demonstrates that cost can be lowered while quality is enhanced. Not only will this save you money, but it is also a strong guarantee of your supply chain’s competitiveness and reliability. We believe that this process is equally applicable to your other complex parts.
We would be very willing to discuss with you how we can apply LS Precision’s solutions to your projects.

Why Do We Need CNC Turning Drawings (PDF)?
To provide CNC turning drawings in PDF format is vital in order to ensure accurate and efficient project initiation and achievement of cost-saving goals. The main reasons are the following:
- Error-proofing and one-of-a-kindness: PDFs are a fixed, non-modifiable format, and you therefore guarantee that the design version you supply is the sole authoritative source for the partnership of the two entities and completely eliminates manufacturing errors and cost loss through hybrid file versions or poor formatting.
- Information integrity: Diagrams are the keeper of all manufacturing specifications. PDFs perfectly maintain all the crucial information, like precise geometric dimensioning and tolerancing (GD&T), materials specs, heat treatment and surface finish requirements, etc. This is an ironclad requirement for our precise process planning and costing.
- Successful cost reduction analysis: Our design engineers conduct design for manufacturability (DFM) analyses against the drawings. Without reference to the drawings, we can identify the potential for optimization quickly, e.g., whether tolerances might realistically be relaxed or whether the structure might be more machineable, thereby proposing realistic cost reduction actions rather than quantifying blindly.
- Seamless Coordination: PDF is very flexible and can be opened without needing specialized software. This implies that all departments, from programming to processing to quality inspection, have a clear and identical picture of the same requirements, which ensures an error-free and smooth manufacturing process.
In short, the PDF drawings you submit are the basis on which we read your specifications, automate processes, and ultimately achieve our goal of costing 40% less. They ensure clear communication among the concerned parties and are the beginning of a successful collaboration.
We eagerly await your drawings and initiating the value analysis process immediately.
FAQs

By taking full advantage of high-efficiency PVD/PCBN tools designed for titanium alloys (three times longer tool life), intelligent CAM programming to optimize automatically tool paths and parameters, high-pressure cooling (HPC) or minimum quantity lubrication (MQL) technology, automated loading and unloading with real-time monitoring, and lean material management (near-net-shape forming and scrap recycling), we achieved reduced processing time per part and significantly reduced tool and material usage. In one case, the overall price of an aviation bracket part was reduced by 42% successfully.
2. Following a 40% savings in cost, how do we ensure the quality of aviation parts?
Complete quality assurance is a requirement. All parameters optimized are put through rigorous DOE validation and test cutting to deliver controlled cutting forces and heat to avoid damaging parts. Critical processes utilize in-line dimensional (tolerance ±0.005mm) and roughness monitoring. 100% of the main components are tested non-destructively, i.e., penetrant or eddy current test. Surface integrity (Ra < 0.4μm) and hardened layers are strictly monitored and third-party fatigue tests are in full compliance with the requirements. The entire process adheres to the AS9100 quality management system.
3. Is the solution suitable for mass production? How efficient and stable is it?
The solution is specifically designed for medium and large-volume production, with more significant outcomes. Single-piece cycle time is reduced by an average of 35% through optimization. Predictive tool changes, real-time process monitoring/compensation, and stable tool wear profiles remove unexpected downtime. Automatic loading and unloading enable continuous operation, which raises Overall Equipment Effectiveness (OEE) by over 25%. Production of tens of thousands of pieces annually has been running smoothly for over 12 months with a batch qualification rate in excess of 99.95% and 100% on-time shipping.
4. Is the solution suitable for my part? Key points to consider
This solution is particularly suitable for titanium alloy (e.g., TC4 and TC11) rotating/rotating aircraft parts (shafts, sleeves, brackets, etc.). Key points to be taken into account are: type of material, complexity of geometry (suitability for turning/milling), current cost impediments (tooling, time, scrap), quality requirements in terms of (tolerances, roughness, fatigue life), and production batch size. We recommend forwarding drawings/processes for complimentary preliminary assessment, or arranging a trial run to establish the actual cost-cutting result.
Conclusion
Through the practical applications described above, we can clearly see that a “40% cost reduction” is not a radical goal achieved by cutting corners or sacrificing quality.
