Influence of the process parameters of incremental forming of personified implants of the cranial bones on their geometry

This work, on the basis of experimental data, establishes a relationship between the incremental forming process parameters and the accuracy of the resulting geometry of personalized implants of the cranial bones. The authors carried out a qualitative and quantitative assessment of the values of the maximum deviation, mean average deviation and standard deviation. It was determined that the use of two passes with incremental forming does not provide an increase in the geometric accuracy of the obtainable implant. The accuracy of the obtainable products increases with a reduction in the step of movement of the deforming tool during incremental forming.
