Installation
Autobend 6 November, 1999 2-55
Referencing the Gauging Surface
Prior to forming parts, the gauging surface must be referenced to the
forming tools. The programmed dimension is the distance from the
gauging surface to the punch centerline. This centerline changes for each
set of tooling.
Two zero reference bars are provided with each Autobend to provide a
quick and controlled method of squaring the gauge bar. Each zero
reference bar has a 90° “V” notch in the center and a machined edge on
one end. The distance from the center of the “V” notch to the machined
edge is 5" (127 mm).
Warning
Do not use the reference bars if the rubber pad is
damaged or missing. This pad is a safety feature to
reduce the possibility of breakage from slight over-
pressure. The pads will not prevent the bars from
breaking in the event of severe over-pressure from the
press brake.
