The Pocket Event will rapid to the center of the circle or rectangle. After you set the cutter and
press GO, it will move in a logical path through the material (leaving the finish cut, if one is
programmed), using 70% of the cutter diameter. After the center is cleared, it will do the finish
cut and ramp away from the part at the end by the amount of the programmed finish cut.
7.3.5 Subroutine Events
The Subroutine Events are used for manipulating previously programmed geometry
within the XY plane.
The Subroutine Event is divided into two options: Repeat and Rotate.
Repeat and Rotate may be connective. As long as the rules of connectivity are satisfied, the
ProtoTRAK EMX will continue milling between preceding and subsequent events.
REPEAT
allows you to repeat an event or a group of events up to 99 times with an offset in X
and/or Y. This can be useful for drilling a series of evenly spaced holes, duplicating some
machined shapes, or even repeating an entire program with an offset for a second fixture.
Repeat events may be "nested." That is, you can repeat a repeat event, of a repeat event, of
some programmed event(s). One new tool number may be assigned for each Repeat Event.
Repeat events may be "nested" up to five deep.
ROTATE
is used for polar rotation of parts that have a rotational symmetry around some
point in the XY plane. In addition to specifying the events to be repeated, you must also
indicate the absolute X and Y position of the center of rotation, the angle of rotation
(measured counterclockwise as positive; and clockwise as negative), and the number of
times the specified events are to be rotated and repeated. You may not rotate another
rotate event. Consider the figure below:
FIGURE 7.3
Shape A programmed with 4 MILL events and Conrads. Using ROTATE,
these 4 events are rotated through a 45 degree angle about a point offset from absolute
zero by X Center and Y Center dimensions. A is rotated 3 times to produce shape B, C,
and D.
