You may change these assumed inputs by simply inputting the correct data when the
event is programmed.

Incremental Reference Position
When X and Y data for the beginning position of any event are input as incremental
data, this increment must be measured from some known point in the previous event.
Following are the positions for each event type from which the incremental moves are
made in the subsequent event:
POSITION/DRILL:
X and Y programmed
BOLT HOLE:
X CENTER and Y CENTER programmed
MILL:
X END and Y END programmed
ARC:
X END and Y END programmed
IRREGULAR POCKET or PROFILE:
X and Y Begin of the programmed leg
CIRCLE POCKET or PROFILE:
X CENTER and Y CENTER programmed
RECTANGLE POCKET or PROFILE:
X1 and Y1 corner programmed position
REPEAT, ROTATE or MIRROR:
The appropriate reference position for the
event prior to the first event that was repeated.
Note - For 3-axis programs, the Z rapid, Z end or depth and taken from the previous
event.

Finish Cuts
The Pocket and Profile events are designed with built-in finish cut routines because they
are complete, stand-alone pieces of geometry. Shapes machined with a series of Mill or
Arc events don't have an automatic routine for making finish cuts.
Instead, it is very easy to get a finish pass by overstating the size of the tool for the
events in the initial pass, and then using a Repeat Event and programming a new tool
with the actual size of the tool.
For the first pass, the cutter will be positioned away from the final cut half the amount of the
difference between the actual size of the cutter and the diameter you put in. When the
Repeat Events are run, the same cutter will be positioned correctly to do the final pass to size.

Look
You can look at part graphics while in the Program Mode. At any time an event is
finished programming and the Select Event prompt appears in the conversation line,
simply press the LOOK hard key. The programmed events are automatically sized so
that everything fits on the screen.
To return to the programming, press the RETURN softkey.
