1.2 Unattended Operation
Fully enclosed Haas CNC machines are designed to operate unattended; however, your
machining process may not be safe to operate unmonitored.
As it is the shop owner’s responsibility to set up the machine safely and use best practice
machining techniques, it is also the owner’s responsibility to manage the progress of these
methods. You must monitor your machining process to prevent damage, injury, or loss of
life if a hazardous condition occurs.
For example, if there is the risk of fire due to the material machined, then you must install
an appropriate fire suppression system to reduce the risk of harm to personnel, equipment,
and the building. Contact a specialist to install monitoring tools before machines are
allowed to run unattended.
It is especially important to select monitoring equipment that can immediately detect a
problem and perform an appropriate action without human intervention.
1.3 Door Rules - Run / Setup Mode
All Haas CNC machines are equipped with locks on the operator doors and a key switch
on the side of the control pendant to lock and unlock setup mode. Generally, setup mode
status (locked or unlocked) affects how the machine operates when the doors are opened.
Setup mode should be locked out (the keyswitch in the vertical, locked position) at most
times. In Run and in Setup mode, the enclosure doors are locked closed during CNC
program execution, spindle rotation or axis movement. The doors automatically unlock
when the machine is not in cycle. Many machine functions are unavailable with the door
open.
When unlocked, setup mode allows a skilled machinist more access to the machine to set
up jobs. In this mode, machine behavior is dependent on whether the doors are opened or
closed. The following charts summarize the modes and allowed functions.
NOTE: All these conditions follow assuming that the door is open and stays
open before, during and the actions occur.
