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 کاملDevelopment of an Empirical Model for Surface Roughness in a Non- Conventional Drilling Process - Evolutionary Approach
Prediction of surface roughness is essential in any machining process as it plays a vital role in determining the quality of components. The present work involves the development of an empirical model for surface roughness of a non-traditional hole-making method, friction drilling process based on a recently emerged evolutionary approach called Genetic programming (GP). The parameters such as d...
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 کاملOptimization of Cutting Parameters for Surface Roughness of Stainless Steel Ss304 in Abrasive Assisted Drilling
This paper is concerned with optimization of surface roughness when drilling of stainless steel SS304 with HSS drill. This study included drilling of SS304 with supply of Sic abrasive having grain size 650 and 1250 mesh size through abrasive slurry system. Abrasives not only used for cooling purpose but also increases the surface finish, MRR and reduce tool wear. Experiments were conducted on a...
