Measurements of Surface Roughness in Conventional and Ultrasonically Assisted Bone Drilling
Bone fracture due to an accident, aging or diseases is a feature of everyday life. One of the principal methods of repair and reconstruction of such a fracture is based on drilling the bone and fixing its separate parts together using screws, wires and plates. Morphology of the drilled hole surface and fixative components such as screws, pins and hooks influences strength of the bonds between t...
متن کاملExperimental investigations of forces and torque in conventional and ultrasonically-assisted drilling of cortical bone.
Bone drilling is widely used in orthopaedics and surgery; it is a technically demanding surgical procedure. Recent technological improvements in this area are focused on efforts to reduce forces in bone drilling. This study focuses on forces and a torque required for conventional and ultrasonically-assisted tool penetration into fresh bovine cortical bone. Drilling tests were performed with two...
متن کاملultrasonic assisted drilling of bone
ultrasonic assisted drilling (usd) is new technique to drill difficult to machine materials. in this method, tool or workpiece vibrates with amplitude of few microns in addition to conventional drill bite rotation. in this experimental research, the bone was drilled both conventionally and using uad, then the thrust was measured in two methods at feed rates of 50, 75 and 125 mm/s and 500, 710 a...
متن کاملEnhanced ultrasonically assisted turning of a β-titanium alloy.
Although titanium alloys have outstanding mechanical properties such as high hot hardness, a good strength-to-weight ratio and high corrosion resistance; their low thermal conductivity, high chemical affinity to tool materials severely impair their machinability. Ultrasonically assisted machining (UAM) is an advanced machining technique, which has been shown to improve machinability of a β-tita...
متن کاملPurification of single-wall carbon nanotubes by ultrasonically assisted filtration
Ž . An efficient method for purification of single-wall carbon nanotubes SWNT synthesized by the laser-vaporization process has been developed. Amorphous and crystalline carbon impurities and metal particles are removed from SWNT samples by ultrasonically-assisted microfiltration. Sample sonication during the filtration prevents filter contamination and provides for a fine nanotube–nanoparticle...
