Non-uniform rational B-spline (NURBS) curves are combined with the Kriging model to present a prediction method of the rail grinding profile for a grinding train. As a worn rail profile is a free-form curve, the parameterized model of a rail profile is constructed by using the cubic NURBS curve. Taking the removed area of the rail profile cross-section by grinding as the calculation index of ...

Grinding hand tools. A die grinder is a high-speed rotary tool that is typically powered by compressed air. The tool has a small-diameter abrasive bit that rotates to get the job done. Check out Choosing the Right Air Die Grinder for more information and some recommended models. Angle grinders are also abrasive hand tools. Unlike die grinders, however, they run electrically.

A universal method of grinding force modeling in arbitrary 2D freeform grinding is proposed, which is based on the infinitesimal approach. The main idea of this method is to discretize the freeform surface into a group of surfaces with very small widths along the profile of the surface cross section, which can be considered as flat surfaces inclined at different angles.

A method is described for grinding a crankpin of a crankshaft using computer controlled wheelfeed and headstock drives ( 44,30,24 ). During a final grinding step leading to finish size the cutting force is maintained on the wheelhead ( 38 ) to keep the wheel ( 34 ) and pin under a moderate constant load and the rotational speed of the headstock drive ( 24 ) is reduced.
