BACKGROUND The relationships between hip abductor and extensor strength and frontal plane hip and knee motions that are associated with anterior cruciate ligament injury risk are equivocal. However, previous research on these relationships has evaluated relatively low-level movement tasks and peak torque rather than a time-critical strength measure such as the rate of torque development (RTD). ...

This present investigation uses the Taguchi and response surface methodology (RSM) for modelling and optimization of the temperature produced during bone drilling. The drilling of bone is a common procedure in orthopaedic surgery to produce hole for screw insertion to fixate the fracture devices and implants. A major problem which is encountered during such a procedure is the increase in temper...

An on-going comparative study of wear rates and tool lives under varying cutting parameters is presented in this paper, along with results indicating the abilities and limitations of the hard turning process to produce finished surfaces with acceptable roughness and integrity. To date, the study has consisted of thirteen combinations of machining conditions. The tests were performed with four d...

-The Aluminum Hybrid Metal Matrix Composites (Al-HMMC) are finding numerous applications in many areas like Automobile, Piston and Cylinder and Aerospace, etc. Adding a third element into the metal matrix composite makes it hybrid. The Reinforcement of SiC and Graphite used in this Al-HMMC improves its strength. The present investigation is to find the optimum machining parameter of CNC turning...

The development of new cutting tool materials during the last few years is based mainly on submicron hardmetal substrates as well as on new PVD and CVD coatings. The development of submicron and nanopowders with higher strength and higher fracture toughness solves problems in machining high-temp alloys, hard materials, and in dry cutting. Based on physical models used to calculate stress in the...

High speed machining (HSM) may produces parts with substantially higher fatigue strength; increased subsurface micro-hardness and plastic deformation, mostly due to the ploughing of the round cutting tool edge associated with induced stresses, and can have far more superior surface properties than surfaces generated by grinding and polishing. Cutting edge roundness may induce stress and tempera...

Imwalle, LE, Myer, GD, Ford, KR, and Hewett, TE, Relationship between hip and knee kinematics in athletic women during cutting maneuvers: a possible link to noncontact anterior cruciate ligament injury and prevention. J Strength Cond Res 23(8): 2223–2230, 2009—The purposes of this study were to compare lower-extremity kinematics during a 45 and 90 cutting maneuver and to examine the relationshi...
