OBJECTIVES The purpose was to assess thermal changes and drill wear in bovine bone tissue with the use of twisted stainless steel and zirconia-based drills, during implant site preparation. METHODS A total of 100 implant site preparations were performed on bovine ribs using a surgical unit linked to a testing device, in order to standardize/simulate implant drilling procedures. Bone temperatu...

-Authors propose the spherical electromagnetic actuator that applied Surface Motor. The feature of this actuator is the ability to arrange the magnetic poles uniformly by distributing the stator's magnetic poles in triangular lattice. In this paper, we report that the fundamental structure of this actuator and secondary side permanent magnets arrangement, and we measure the thrust force charact...

Gait modification offers a noninvasive option for offloading the medial compartment of the knee in patients with knee osteoarthritis. While gait modifications have been proposed based on their ability to reduce the external knee adduction moment, no gait pattern has been proven to reduce medial compartment contact force directly. This study used in vivo contact force data collected from a singl...

The present study investigates the effects of machining parameters and tool coating during drilling a GLARE® hybrid aerospace material on cutting forces, hole quality generation harmful dust particles. tests were conducted using twist drills with diamond-like carbon (DLC), Cristall without coating. Obtained results indicate that feed, in contrast to spindle speed, has an important effect thrust...

Abstract Currently, the use of sustainable products and technologies is growing; consequently, mineral-origin basalt fibre-reinforced polymer (BFRP) composites are becoming more popular in industries. Although BFRP parts require mechanical drilling operations for manufacturing holes assembly, many challenges make process difficult. Considering that cutting force one main parameters characterisi...
