An Estimation of Required Rotational Torque to Operate Horizontal Directional Drilling Using Rock Engineering Systems
Horizontal directional drilling (HDD) is widely used in soil and rock engineering. In a variety of conditions, it is necessary to estimate the torque required for performing the reaming operation. Nevertheless, there is not presently a convenient method to accomplish this task. In this paper, to overcome this difficulty based on the basic concepts of rock engineering systems (RES), a model for ...
متن کاملA new approach to enhance final surface quality in drilling operation: evaluation of using alumina micro-particle additives on oil-water emulsion cutting fluid
Reaming is a common finishing process for improving the drilled holes surface quality. Choosing an appropriate finishing method in drilling process has a significant effect on the surface quality of holes and in decreasing the process total cost and time. In this study, four similar holes were drilled on the AISI 4340 workpiece with different two pair feed rates. The drilling process was perfor...
متن کاملTibial Tunnel Aperture Irregularity Following Drilling with Five Different Reamer Designs: a Qualitative Micro-CT Analysis
INTRODUCTION: Historically, tibial tunnel creation in ACL reconstruction was performed by antegrade insertion of a tibial guide pin followed by antegrade reaming from the anteromedial tibial metaphysis (distal aperture) to the tibial plateau (proximal aperture). In the last few years retrograde reaming has been introduced.[1, 2] It has been theorized that the retrograde tibial tunnel drilling t...
متن کاملA COMPARISON OF PERFORMANCE OF SEVERAL ARTIFICIAL INTELLIGENCE METHODS FOR ESTIMATION OF REQUIRED ROTATIONAL TORQUE TO OPERATE HORIZONTAL DIRECTIONAL DRILLING
Horizontal Directional Drilling (HDD) is extensively used in geothechnical engineering. In a variety of conditions it is essential to predict the torque required for performing the reaming operation. Nevertheless, there is presently not a convenient method to accomplish this task. To overcome this problem, in this research, the application of computational intelligence methods for data analysis...
متن کاملA Bone Reaming System with Tactile Temperature Display
A bone reaming system with temperature tactile sensation display was developed for potential use during bone internal fixation surgery. The developed reaming system will allow tracking of the amount of heat generated inside fractured bones by surgeons throughout the reaming process. It consists of a temperature sensing system to measure the bone cavity temperature, a rotor system to provide the...
