1.5 Setting the part zero.
The part zero is set on the Z axis.
Programming gets complicated when done from the
machine reference zero (O
M
) and it is only good for that part
in that position. When programming from a part zero (O
P
),
the part dimensions may be obtained from the blueprint.
When machining several parts, the distance from machine
reference zero (O
M
) to the part is different for each of them.
It would require running a program for each part. When
programming from a part zero (O
P
), it is irrelevant where the
part is fixed.
O
M
: Machine zero.
O
P
: Part zero.
