The Most Important Thing About Titanium Processing Is The Following Points

Low thermal conductivity; so that the heat generated by cutting is not quickly dissipated by conduction to the inside of the workpiece, but concentrated on the cutting edge and face. The high temperatures reached can cause tempering and dulling of the cut parts, further increasing the temperature and further shortening the tool life.

Highly chemically reactive with almost all materials, especially at high temperatures; this can cause wear, micro-welds and cutting tool spread.

Low-level elastic modulus: Popular in the final product, but may initially present some difficulties in processing. Under tool pressure, elastic materials tend to move away from the cutting zone, especially during light passes. Thinner parts are deflected, and instead the cutting edge tends to slide along the workpiece and vibrate and generate heat.

Work-induced hardening means that there is virtually no built-up edge. The absence of a fixed block of material in front of the tool results in a high cutting angle. This results in the formation of thin chips that are in contact with a relatively small area of the tool face, resulting in high loads on the section elements. This fact, combined with the use of tools that are not geometrically appropriate and may not be sharp, tends to push the material rather than cut, creating stress and causing plastic deformation. Plastic deformation, in turn, hardens the material, which increases stiffness and resistance so that the correct cutting speed at the start of the job becomes too high and the tool wears too much.

Stresses can occur in the material, mainly due to severe deformation of the product during the forging process. This applies in particular to high-strength alloys. For example grade 5 titanium.

Stresses and changes in mechanical values may apply to alloyed titanium with high strength. This may be caused by high forging shock, low forging temperature, or insufficient mixing of elements during ingot fusion. Titanium also has a tendency to return to its original shape. This can cause problems when machining thin-walled products with narrow tolerances.

Often, those trying to work with titanium spend a lot of time finding tools. Their calculations were based on traditional data for other materials and did not observe the described characteristics, which clearly define the working criteria to be employed and are applicable to basically all types of machine tools and titanium.
