Abstract
A method of monitoring and inspecting an edge of strip metal includes providing at least one image producer having a field of view that substantially frames the edge, using the at least one image producer to form a first series of images of the edge after the edge has been formed by a knife; and analyzing in real time the first series of images to determine the shear angle and/or the burr height of the edge.
Claims13
A method of monitoring an edge of strip metal, comprising the following steps:
- providing at least one image producer having a field of view that substantially frames the edge;
- using the at least one image producer to form a first series of images of the edge after the edge has been formed by at least one knife;
- and
- analyzing in real time the first series of images to determine the shear angle of the edge.
1 more element
An apparatus for monitoring an edge of strip metal, the apparatus comprising:
- at least one image producer having a field of view that substantially frames the edge, said at least one image producer operable to form a first series of images of the edge after the edge has been formed by at least one knife;
- and
- an analyzer connectively associated with said at least one image producer, said analyzer operable in real time to determine the shear angle of the edge and to compare the shear angle to a standard operating parameter for shear angle.
