14) Never touch a machine control device or electrical component when your
hand is wet. Keep flammable liquids and materials away from the work area
and chips.
15) Never clean up chips while the machine is running or is in automatic mode.
16) Do not file work pieces being rotated under power.
17) At the end of the work day the machine should be placed in either “control
off” or “power off” modes.
18) When restarting a machine after it has been shut down, always assume it
has been tampered with. Recheck all phases of the job as though you were
running the first piece.
19) Never touch spindle start or spindle jog control until hands, feet, and body
are well clear of the work area.
20) Coolant and oils can make surfaces on the machine slippery. They can also
present an electrical hazard if the machine has power on. For these reasons
do not stand on any part of the machine at any time.
21) Never extend an unsupported bar out of the rear the spindle or hydraulic
cylinder a distance from a concentric support more than 10 times of its
diameter. Doing so can cause the bar to bend or break. When any bar is
extended, a large sign should be placed to warn people to stay away from the
area.
22) If your turning machine has a bar-feeder interfaced to it,
keep yourself
and others away from the exit end of the bar-feeder when the
machine running.
1.1.1 Safety instructions for work holding
1) Never run a job on this machine until you are 100% sure the work piece is
being held in such a manner as withstand the centrifugal force from rotation
and cutting forces of the tooling. If there is any doubt, whatever, consult with
your supervisor.
2) A chuck is the most common work holding device used on this machine.
Some of the factors affect the holding device used on this machine. These
factors which affect the holding ability of a chuck are :
* Clamping force of jaws
* Rotational speed of the spindle
* Type of jaw surface (serrated, smooth, etc.)
* Area of chuck configuration of the work piece…shape, weight, and balance
* Jaw weight and location
3) With air or hydraulic actuated power chuck (optional accessory), make sure
the jaws are gripping the work securely before they reach the end of their
