One- end coordinate
Many times part drawings will only give a programmer one--axis
dimension for a tool path and require that the other axis dimension be
calculated by the angle. The following QPP feature eliminates the need for
this calculation. This must be a linear block (see section 15.3 for circular).
The format for this block is as follows:
,A__ {X__};
Y__
Where : Is :
,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.
X,Y End Point - This word is used to program one of the coordinates of the end point
of a linear path. The control will calculate the other end point automatically. This
can be any axis word that is in the current plane.
Only one axes word from the current plane may be programmed in this
block. Any axis word that is not in the current plane will be executed as a
normal linear move to that coordinate and combined with the QPP
generated tool path.
If both axis words from the current plane are entered in the block, the angle
is ignored and the control moves to the coordinate position programmed
with the axis words. All examples in this section will assume the XY
plane is active.
Important: If the programmed tool path is going to be parallel to an axis
in the current plane, the axis word for the end point in the block should be
for the axis in the current plane that is parallel to the tool path. This means
if the value of the angle (,A word) is 0 or 180 degrees the second axis in
the plane must be programmed in the block. If the value of the angle is 90
or 270 degrees the first axis in the plane must be programmed in the block.
