This research aims to investigate using spindle power consumption signals obtained directly from an industrial drilling system to monitor tool wear evolution.
Additionally, the complexity of drilling in hybrid stacks further compounds the challenges of this process.

In-process monitoring and empirical modeling of the tool wear in turning of aluminum alloys using thermoelectric signals.

Introduction Titanium (Ti) and its alloys are widely used to manufacture of dental implants, maxillofacial and orthopaedic prostheses.
Using the same approach of controlled anodization in dilute fluoride electrolytes, nanotubes of intermetallic titanium compounds such as Ti-Al [123], binary alloys such as TiNb [119], TiZr [126] or on complex biomedical alloys such as Ti-6Al-7Nb [121] and Ti-29Nb-13Ta4.6Zr [124] were successfully fabricated.

AISI H11 tool steel is a complex tool steel alloy used to manufacture hot forging dies.
The main aim was the development of a novel WP-LMD process, and consequently a new H11 tool steel with improved toughness and hardness.
Nonetheless, several other materials can also be used, which are difficult to obtain in wire form such as tantalum, titanium diboride compound, and tungsten.

These oxidation products are mostly volatile organic compounds that cause off-odors [3].
Since some of these compounds are colored, their use is limited [10].
The lower frequency value represents the presence of carbonylic compounds and the more advanced oxidation process.
It means photo-oxidation happens very quickly and causes loss in phenolic compounds [40].

As a result of studying the increase in scale during firing in depending on the steel grade, it was found that if alloying additives (Ni, Cr) are present in the steel, its mass increase at 800°С for 10 min 0.2 mg / cm2, for ordinary mild unalloyed steel 4 ... 6 mg / cm2.
