Using QuickPath Plus

Chapter 15

15-3

If an angle is programmed in a circular QuickPath Plus block, an error is
generated.

If an L-word is programmed in a G13, or G13.1 block an error is
generated.

One End Coordinate

Many times part drawings give a programmer only one axis dimension for

a tool path and require that the other axis dimension be calculated by the

angle. This QuickPath Plus feature eliminates the need for this calculation.

This must be a linear block. See section 15.3 for circular block.

The format for this block is:

,A__

X__

Angle

This word is used to define the angle of a tool path. This manual

assumes that the ,A-word is used. The angle is a positive value when

measured counterclockwise from the first axis defining the currently active

plane and a negative value when measured clockwise. The angle is in

units of degrees.

X,Z End Point

This word is used to program one of the coordinates of the end point of a

linear path. The control calculates 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 can be programmed in this

block. Any axis word that is not in the current plane is executed as a

normal linear move to that coordinate and combined with the QuickPath

Plus 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 assume that the ZX 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 not parallel to the tool path. This

means if the value of the angle (,A-word) is 0°or 180°, the second axis in

the plane must be programmed in the block. If the value of the angle is

90°or 270°, the first axis in the plane must be programmed in the block.
