The conventional threshold for the minimum web or recessed surface depth in precision-machined titanium alloy components, particularly those utilized in aircraft spars, stood at 0.100 inches, barring the utilization of costly supplementary tools that could sustain the typical tolerance range of ±0.010 inches for thinner recessed surfaces. Alternatively, chemical milling methods were often employed to achieve the desired thinness.

Regarding the rigidity and ease of processing in pure titanium variants, we commence with Ti-99.5, categorized as grade 1, which exhibits a firmness level of 100 on the HRC scale and a processability rating of 46%. Progressing to Ti-99.6, designated as grade 2, it demonstrates a reduced hardness of 90 HRC and a marginally lower machinability at 40%. Lastly, Ti-99.7, classified as grade 3, boasts a further diminished hardness of 80 HRC accompanied by a decreased machinability of 35%.

Regarding machinability, aluminum's reduced mass and inherent softer texture facilitate machining processes compared to titanium. Nevertheless, titanium's remarkable resistance to corrosion far surpasses that of aluminum, rendering it a preferable material for applications that encounter severe environmental conditions. 19th October, 2023

Advice on machinery selection for titanium processing

Additionally, maintaining a low RPM range, oftentimes, a setting of 3000 RPM suffices, considering the employment of carbide cutting tools that necessitate a slow cutting velocity, ranging from 45 to 100 meters per minute. The utilization of internal coolant is imperative, and its efficacy enhances with increased levels.

Techniques such as water jetting, band sawing, laser-based slicing, and plasma cutting are all viable options for achieving precise and productive titanium cutting operations.

The prevalent choice for laser cutting titanium sheets typically involves utilizing CO2-based machinery, with nitrogen or oxygen serving as auxiliary gases to facilitate the process.

The processing of titanium alloys poses significant challenges, stemming from their inherently elevated tensile strength, diminished ductile yielding capacity, a modulus of elasticity that is approximately 50% less (at 104 GPa), and a thermal conductivity markedly lower by roughly 80% compared to steel.

When it comes to machining titanium, the optimal choice of tooling lies in carbide-tipped instruments endowed with a PVD coating. Furthermore, advancements in technology have introduced novel, enhanced coating alternatives, notably TiAIN (Titanium Aluminum Nitride), which offer additional benefits. Given titanium's inherent resilience and springiness, the utilization of a keenly sharpened tool becomes paramount to achieving efficient and precise cutting operations.
