Pathology involving the long head of the biceps tendon is a common and significant cause of shoulder pain. For active patients with refractory biceps tendinosis, tenodesis of the tendon to either soft tissue or the humerus is the preferred surgical treatment. Subpectoral biceps tenodesis to the humeral diaphysis with an interference screw has been gaining popularity as an effective method for t...

The aim of this investigation is to devise a robust detection method for drill bit break-through when drilling into long bones using an automated drilling system that is associated with mechatronic assisted surgery. This investigation looks into the effects of system compliance and inherent drilling force fluctuation on the profiles of drilling force, drilling force, drilling between successive...

Drilling operations have an important role in manufacturing industries and the application range is about 33% among machining methods. In drilling processes, hole quality affected by workpiece material, parameters, drill diameter, bit features. this study, surface of wear were investigated experimentally when AISI 1040 steel Al7075 aluminum workpieces with twist drills. Three different types bi...

Information transmission is an important part of the wellbore trajectory automatic control system. Combined with the characteristics of the guided drilling system, drilling fluid pulse is selected as a tool for trajectory control. Negative pulse transmission of drilling fluid is one of the key technologies to realize wellbore trajectory automatic control. In this paper, the working principle of...

The aim of this work is to analyze the micro mechanisms underlying the wear of macroscale tools during diamond machining of SiCp/Al6063 composites and to develop the mechanism-based diamond wear model in relation to the dominant wear behaviors. During drilling, high volume fraction SiCp/Al6063 composites containing Cu, the dominant wear mechanisms of diamond tool involve thermodynamically activ...

This work studies the open hole surface integrity of Al 2024-T3/Ti-6Al-4V stacks, which have been subjected to different making methods, namely, conventional drilling and helical milling. The resulting hole-exit burr, roughness machined surface/sub-surface microstructures characterized impact on fatigue performance coupons has revealed. Results show that milling can effectively reduce burr form...
