7.7 Assumed Tool Offset, Feedrate, and Tool #
When the INC SET key is pressed, the ProtoTRAK EMX will automatically program the following
for these prompts:
TOOL OFFSET:
for a Mill or Arc Event, same as the last event if that event was a Mill or Arc
Event, otherwise, Tool Center.
FEEDRATE:
same as last event if that event was a Mill, Arc, Pocket, or Profile.
TOOL #:
same as last event, or Tool 1 in the first event.
You may change these assumed inputs by simply inputting the correct data when the event is
programmed.
7.8 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
CIRCLE POCKET or PROFILE:
X CENTER and Y CENTER programmed
RECTANGLE POCKET or PROFILE:
X1 and Y1 corner programmed position
REPEAT:
The appropriate reference position for the event prior to the first event that was
repeated.
Note - For 2 ½ axis programs, the Z rapid, Z end or depth and taken from the previous event.
