Purpose: of this paper is to present some technological problems with forming of the titanium implants and medical tools by the plastic working methods. Design/methodology/approach: Application of the new biomaterials such as titanium alloys needs to carry on tests on optimisation of the methods and parameters of the plastic working, therefore some experiments in order to determine the friction coefficient or analyse the influence of the cutting methods on the cut-surface appearance were done. Findings: As far as stamping is concerned, it was found that the proper lubrication not only decreases frictional resistance but also limits or even completely eliminates creation of the titanium "build-ups" on the tools. As far as cutting methods are concerned, the cut-surface significantly depends on the applied cutting method. Guillotining, laser and abrasive waterjet cutting were taken into consideration. Guillotining and laser cutting influence the titanium microstructure mostly. Abrasive waterjet cutting does not cause any changes in microstructure. Research limitations/implications: An application for the implants almost unworkable biomaterials, such as titanium alloys, needs overcoming many technological barriers such as proper selection of the lubricant, deformation temperature, strain velocity etc. Moreover, titanium belongs to the very expensive materials, so material costs are the main research limitation. Practical implications: The investigations of the friction coefficient or the influence of the cutting method on the cut-surface quality are important for producing both implants and surgical tools by such methods as: cutting, blanking, bending, stamping, etc. Originality/value: There are only a very few works on the sheet-metal forming processes of the titanium alloys, so each new information on the titanium deformation is valuable.
