Not Any Mutual Sliding On Grinding Surfaces

Friction plots of polymers sliding on smooth metal surfaces are generally characterized by two regions of distinct dependency on the normal load, with low sensitivity at low stress levels followed by a sharp change in the rate of decrease of friction with increasing pressure at levels above the plastic flow limit of the polymer. A simplified model is proposed to describe this behavior which

  • Fishtailing Wikipedia

    Fishtailing is a vehicle handling problem which occurs when the rear wheels lose traction, resulting in can be caused by low friction surfaces sand, gravel, rain, snow, ice, etc.. Reardrive vehicles with sufficient power can induce this loss of traction on any surface, which is called poweroversteer.

    Unlike centertype or chuckertype grinding, parts made using a centerless process do not require center holes, drivers or workhead fixtures. Instead, the workpiece is supported on its own outer diameter by a workblade located between a high speed grinding wheel and a slower speed regulating wheel with a smaller diameter.
