WebMar 1, 2024 · This study investigated the grinding force in rotational atherectomy, a clinical procedure that uses a high-speed grinding wheel to remove hardened, calcified plaque inside the human arteries. The grinding force, wheel motion, and ground surface were measured based on a ring-shape bovine bone surrogate for the calcified plaque. At … WebMar 2, 2024 · Tangential force is influenced by coolant lubricity, grinding wheel sharpness, abrasive grain density, workpiece material properties and wheel profile. It is possible to calculate the tangential forces (F t) acting on the wheel in creepfeed grinding in two ways. The first is directly from the grinding spindle power and wheel speed as shown:
