Tool Offset
MILLPWR
G2
will calculate the actual tool path when using left and
right offsets. Program the dimensions of the part as identified by the
part drawing.
Program a line, arc, frame, etc. using the “Tool Offset” field to tell
MILLPWR
G2 which side of the line the tool is to be on. See "Tool
Radius Offset" on page 50.
To determine which offset to use: If the tool needs to be on the left
side of the line, use a LEFT offset. If the tool needs to be on the right
side of the line, use a RIGHT offset.
When using a CENTER offset, the programmed dimensions are for the
center of the tool. For some milling functions, like frame and arc,
INSIDE and OUTSIDE offsets are available to make it easier to define
the tool offset.
Datum Selection
The datum is where workpiece (absolute) zero is located. See "Steps
to Establish the datum" on page 81.
If the datum isn't defined on your print, then determine the datum
based upon where most of the dimensions originate.
 Pick a point which will let you enter most of the dimensions directly,
with fewest calculations.
 Establishing a datum requires that the Z retract position be provided
(the position the quill returns to between program steps).
 By setting a retract position, you can ensure that the tool you are
using does not make contact with your workpiece when the quill
moves from one position to the next.
 Establish a retract position for the Z axis each time the console is
powered, otherwise the MILLPWR
G2
will use the quill’s previous
retract position.
A two axes system also requires the Z depth, and Z retract
position. The operator will be prompted to manually move
to a depth, or retract position.
