The FTM-1 is a multi-process machine that incorporates tube
straightening, cutting, forming, and bending processes into one
machine. The operator interfaces with the FTM-1 through an HMI,
where values such as part length and degree of bend can be selected
for tube processing. Tubing is received from a coil via the payoff.
Upon receiving the tubing from the coil, the tubing is pulled
through a series straightening rollers via the feed mechanism. After
being straightened, it will then cut the tube to length and enter an
end-former where both ends of the tube will be reduced. Upon exiting
the end-former, the tubing will be picked and moved by a fully
integrated robotic arm. The robot will transition the tubes, two at
a time, to a bender. After the bending operation is complete, parts
will be dropped down into a catch area where they can then be
removed from the machine.
The FTM-1 is guarded with both hard guarding and a light curtain
array. The use of light curtains enables the operator to gain easy
access into the machine when needed and provides optimum operator
observation while the machine is running in auto mode. There are
multiple e-stops provided, including at the HMI, robot teach pendant
and robot controller. The robot itself is tied into the safety
circuit of the FTM-1, so if a fault occurs (such as light curtain
being blocked or HMI e-stop being activated), the robot will come to
a controlled stop and robot servo power will then be dropped. The
robot cannot be moved while the light curtain is blocked, or the
machine is e-stopped.
