5.8.2 Setup sequence
The setup sequence varies according to the type of workpiece support device mounted on the table. As
the machine may use support equipment made up by the customer, the customer is required to
adequately instruct the personnel responsible for machine operation about the specific workpiece
support devices used for processing.
5.8.3 Checking proper piece blocking
The counter-profiles are not supplied with the machine.
The following example is provided only for information purposes.
NOTE
Safety warning
DANGER!
Danger of the piece or tool parts flying off the machine.
Improper or inadequate blocking may cause:
The piece to fly off
The tool to break and fly off the machine.
Check that the piece is properly blocked before starting the work cycle.
After having fitted and adjusted the blocking devices, including any counter-profile, check that the piece
has been blocked properly. Check that the piece is blocked in every direction in which machining
pressure may be applied.
5.8.4 Machining check
NOTE
Safety warning
DANGER!
Danger of the piece or tool parts flying off the machine.
An erroneous piece program or a piece program applied to a piece that is not blocked
properly may cause the tool to break and tool fragments to fly off the machine.
Check the piece program before starting machining.
Once the machine has been equipped, the operator in charge of running the machine must check that
the work cycle is executed as required. Generally, checks carried out in the original conditions are the
best. The only difference with the final cycle is that the operator holds the portable control and reduces
the machining speed using the potentiometer in order to be able to intervene quickly in the event of
programming or equipping errors, etc.
