How To Eliminate Edge Oxide In Aviation Titanium Alloy Machining Via Gas Purity?

When grade 5 titanium alloys are cut at temperatures higher than 1500, they will readily react with oxygen to produce a brittle layer that compromises the strength of your product parts. This is a major issue you might encounter in aerospace grade titanium laser cutting services. Properly adjusting assist gas purity is the main factor to not only eliminate this problem but also ensure part quality.

Core Requirements for Assist Gas Purity

Making LS Manufacturing your choice for grade 5 titanium laser cutting guarantees that they will only use 99.999% pure argon or helium, instead of the industry standard 99.9% purity gases.

How To Compensate Thermal Deformation For Titanium Laser Cutting Service​ At ±0.02mm Tolerance?

Laser cutting thin walled aerospace structural components is an easy way to build up heat in the metal, which can cause the metal to warp and therefore it can be difficult to get the 0.02mm tolerance requirement. This is one of the big problems in precision titanium laser cutting that you may face. LS Manufacturing's proprietary technology can really help you sort this issue.

Segmented Cooling Cutting Algorithm

One of the ways that LS Manufacturing's segmented cooling cutting algorithm achieves the same part temperature is by using a cutting path that starts with cutting non critical holes first and only then cuts the contours. It facilitates the dispersion of thermal stresses in the parts, and also prevents deformation resulting from the local overheating of the parts by keeping a stable temperature for the parts that you want. Furthermore, it guarantees the dimensional accuracy of the parts that you require.

Real Time Focus Compensation Technology and Practical Data

Real time focus compensation technology changes the laser focus position moment by moment to offset dimensional deviations resulting from thermal deformation.

Here are some test data of cutting a 3mm thick plate of grade 5 titanium by which you can be 100% sure about the precision that this technology can give you:

Cutting Method	Hole Roundness Deviation	Contour Tolerance	Flatness	Pass Rate
Conventional Laser Cutting	0.032mm	±0.035mm	0.08mm	78%
Segmented Cooling + Focus Compensation	0.015mm	±0.018mm	0.03mm	99.2%

How To Solve Slag Hanging In Laser Starting For Aerospace Titanium Parts?

Depending on the circumstances during the laser arc ignition, hard slag can easily form on the underside of the part and it will affect assembly accuracy of your product, and in some cases may even cause part scrap, which leads to higher cost. Indeed, it is a frequent issue that may arise in the laser cutting of complicated airframe titanium parts.

Progressive Drilling and Energy Ramp Control Technology

With LS Manufacturing's progressive drilling and laser energy ramp control technology, the laser energy can be controlled so that it gradually increases from very low to very high levels. Material is then penetrated slowly. Reducing the production of slag, improving the cutting quality during the very first step, preventing the subsequently cleaning operations and saving you both time and money are the results of this new procedure.

Parameter Optimization Based on Titanium Alloy Properties

Given that titanium alloy has a melting point of 1668, our team at LS Manufacturing is able to accurately adjust the nozzle height and laser frequency for you. This results in the slag being blown away by the auxiliary gas and not sticking to the part surface, which in turn leads to a higher assembly accuracy of your desired parts and a reduced scrap rate.

Case Study: LS Manufacturing Customizes Grade 5 Titanium Plates For Top Aerospace Agencies

Thermal deformation control and high accuracy in the dimensions are the main obstacles to tackling the machining of complex aerospace titanium parts. Here is a case study of how LS Manufacturing supported a top 10 global aerospace agency in solving these issues, and you can also use it as a reference.

Client's Problem

One of the top 10 aerospace agencies worldwide had to machine a 0.8mm thick grade 5 titanium alloy fluid distribution plate containing more than 500 irregularly shaped, slender holes, with a hole spacing of only 1.5mm. Due to the previous supplier's poor thermal deformation control, the part yield rate was less than 30%, the development cycle was delayed, and there was a significant wastage of raw materials, these are problems that you may also encounter.

LS Manufacturing Solution

The team did a free DFM review of the part drawings after getting the request and we discovered that the cutting path of the old supplier was very unreasonable and caused the heat from the cutting to be concentrated at one point, thus leading to thermal stress. Based on this, we came up with a multi technology collaborative solution:

1. The addition of a water cooled laser cutting stage so that the heat generated during the cutting process is absorbed in real time and the surface temperature of the parts is kept below 80℃, thereby a reduction in the heat deformation of the parts from the source.
2. The use of a nanosecond level short pulse laser to limit the laser material interaction time, thus decreasing the heat affected zone and avoiding that the lining of the hole be melted and the porous walls deformed.
3. Designing a special silicon carbide fixture which not only fixes the parts but also helps in heat dissipation, at the same time physically shaping the parts to prevent warping after cutting.
4. Changing the cutting path, using the logic of an "inside out, segmented cutting" in order to thermal stress dispersal and thus preservation of hole position and flatness.

Results and Value

The aerospace agency managed to control the flatness of fluid distribution plate within 0.03mm and the deviation of hole position 0.015mm by using the above approach. The yield rate of the component increased dramatically from less than 30% to 99.5%, at the same time, the R&D turnaround time was shortened by 40% and the expensive process of electropolishing was completely avoided. This is the real benefit of partnering with LS Manufacturing, the company the agency is going to work with on a long term basis as they've already signed the contract.
