Abstract

See full text

An apparatus for trimming a sheet metal workpiece includes a base to support the sheet metal workpiece at a working position on the base. A shearing tool is connected to the base to trim the sheet metal workpiece by mechanically inducing a shearing stress on the sheet metal workpiece to form an edge at an edge location on the sheet metal workpiece. A heater is connected to the base to define a heated region on the sheet metal workpiece by heating at least the edge location on the sheet metal workpiece after the sheet metal workpiece is in the working position. The apparatus includes a temperature sensor to detect a surface temperature of the heated region.
