The unchangeable need of securing and locating parts during different manufacturing processes turned the fixtures to key elements in many part production industries. The iterations between design engineers and manufacturing planners because of late collision detection of the part/fixtures with robots cost a lot of time and money. The lead-time can be reduced by developing tools and/or methods f...

An experimental study of the effect of fixtureworkpiece conformability on system static stability is presented. Conformability is defined as the geometric similarity between the workpiece and the smallest polyhedron fit over all fixture-workpiece contacts. Two metrics, C1 and C2, are introduced to quantify global and local conformability, respectively. The elastic displacement of the workpiece ...

To investigate the biomechanical performances of artificial cervical disc (ACD) prostheses, many studies have been conducted, either with sections cadavers under physiological loads or block-like testing fixtures obeying ASTM F2346 standard. Unfortunately, both methods are almost impossible to utilize for accurate results lifetime anti-fatigue experiments at least 10 million cycles due difficul...

Cranial implants are used to secure intracranial structures, reconstruct the skull contour, normalise cerebral haemodynamic and repair cranial defects. Larger bone defects require intervention for from an implant made autologous or other material. To such using implants, materials necessitate biocompatibility with natural bone. Patient-specific designed specific following standard procedures de...
