Using QuickPath Plus
•
The QuickPath Plus (QPP) feature is offered as a convenient programming
method to simplify programming. This method of programming can prove
useful in simplifying the programming of a part directly from a part
drawing. In this chapter we describe:
How to use: On page:

Circular QuickPath Plus 15-7
The most significant advantage of the QPP feature is that the programmer
no longer needs to calculate the end-point of every block or every point of
intersection. QPP will determine these points from angles and lengths.
QPP uses the following addresses:
,A Angle - This word is always displayed as by the control even if the angle is
named differently in AMP. If you have a 9/240 program that uses a different
address than ,A and you want to run the program on a 9/230, 9/260 or 9/290
control the angles will work but the control names them ,A.
L Length - This word is used to define the length of a linear tool path, the direction
of which is determined by the angle (A). The length will always be interpreted as
an incremental distance.
The control offers a variety of sample patterns with prompting to aid in the
programming of QPP. These are found under the QuickView feature
discussed in section 5.3.
Keep the following in mind when programming QPP:
When programming using QPP, any axis words that are programmed
must be in the current plane; and angles are measured from the first axis
defining that plane. All examples in this section will assume the XY
plane is active (angles are measured relative to the X axis).
QPP always uses “,A” as the angle word. When creating new programs,
you should always program the QPP angle with ,A. The system
installer has the ability to define in AMP an additional letter that can
also be used for the QPP angle. Refer to your system installer’s
documentation. This additional QPP angle word is provided only for
program compatibility with older systems.
