This paper presents a novel and scalable experimental platform for biomechanical analysis of tissue cutting that exploits a triaxial force-sensitive scalpel and a high resolution vision system. Real-time measurements of cutting forces can be used simultaneously with accurate visual information in order to extract important biomechanical clues in real time that would aid the surgeon during minim...

This work proposes a process planning for machining of a Floor which is the most prominent elemental machining feature in a 21⁄2D pocket. Traditionally, the process planning of 21⁄2D pocket machining is posed as stand-alone problem involving either tool selection, tool path generation or machining parameter selection, resulting in sub-optimal plans. For this reason, the tool path generation and...

Titanium alloy Ti–6Al–4V and nickel-based superalloy Inconel 718 have been widely employed in modern manufacturing. The published literature on high speed machining (HSM) of the two materials often involves different machining set-up, which makes it difficult to directly apply the research findings from onematerial to the other to select the most appropriate tool geometry and cutting conditions...

OBJECTIVE The compressive tolerance of the cervical spine has traditionally been reported in terms of axial force at failure. Previous studies suggest that axial compressive force at failure is particularly sensitive to the alignment of the cervical vertebra and the end conditions of the test methodology used. The present study was designed to develop a methodology to combine the data of previo...

in this study, stability of geosynthetic reinforced soil retaining walls investigated using plaxis code that is based on finite element method. the effects of axial stiffness, length and vertical space between geosynthetic layers, internal friction angle of soil wall and cohesion of foundation on deformations of wall and maximum axial force of geosynthetic have been investigated. results of ana...

The paper reports an advanced finite element analysis code for the investigation of the cutting process of rectangular groove. Three different restricted contact tools (RC tools) with rectangular, trapezoidal and double-trapezoidal shapes were employed in this study. The cutting force, feed force and rake face temperature distribution during the cutting process were analysed. The simulation res...

Research of virtual surgical operations has advanced in recent years based on virtual reality technology. One basic operation is virtual cutting simulation. In order to realize the virtual cutting, there are two types of research, i.e. using a voxel model and a polygonal model.The voxel model expresses volume and is made by a small cube size. The polygonal model expresses the surface and is con...

Abstract In recent years, as a new type of gob-side entry retaining method, roadway automatically formed by roof cutting and pressure releasing (RAFRCPR) has been widely used in China. Under the condition deep mining, deformation gangue rib is difficult to control, it for traditional I-shaped steel provide needed support. To effectively control rib, U-shaped retractable prevention structure (UR...

Based on the lotus root slicing machine of crank-slider style designed by the authors, the virtual prototype model of slicing machine has been established by the software of PRO/E, and the kinematics and dynamics performances of the slicing machine were studied by utilizing ADAMS. At the same time, analyses were made on the changes of the cutting velocity and acceleration of blade, the force co...

Power reciprocating saws are used in surgical procedures to cut bone. Improved cutting rates are desirable in order to reduce operative time and improve patient outcome. A fixture was developed to test the effect of blade speed on cutting rate of bovine cortical bone. It was hypothesized that the volumetric cutting rate would increase in a linear manner for a fixed stroke length and a constant ...
