THE EVOLUTION OF A CANTILEVER SENSOR TO MEASURE NORMAL AND FRICTIONALFORCES IN THE ROLL GAP DURING COLD-ROLLING

A description is given on the evolution of a cantilever sensor for the measurement of normal and frictional forces acting at the roll-billet interface. This study is an attempt to develop a reliable sensor from which experimental measurements are accurately obtained. A developed sensor which has successfully detected interface forces in the roll ga p during cold rolling of 1100 aluminium is presented. The accurate res ults obtained with this sensor show this design to be a marked improve ment over previous sensor designs to measure frictional forces. Theref ore, the developed sensor is a viable proposition for measuring normal and frictional forces in the roll gap.
