ABSTRACT:
A machine is presented for measuring normal and tangential belt forces as well as the grinding friction force all versus the angular position for abrasive belt grinding. Normal and tangential force transducers, having the same surface shape and surface finish as the contact pulley, are assembled in the contact pulley. The instrumented contact pulley is used as a driving or driven pulley. A variable speed D.C. motor rotates the driving pulley. A cylindrical workpiece is driven by a variable speed A.C. motor through a torque sensor. The torque sensor determines the grinding friction force between the workpiece and the belt. The A.C. motor-torque sensor assembly is mounted on a carriage plate which slides on two rails with linear bearings. Means are provided for applying a predetermined belt tension and means are also provided for applying a workpiece grinding normal force.
