Use the scaling feature to reduce or enlarge a programmed shape. This

feature is enabled by programming a G14.1 block as shown below:

G14.1 X__ Z__ P__;

Where: tell(s)the control :

X, and Z theaxis oraxesto be scaledandthecenterof scalingforthoseaxes. Canbe

anyvalidaxis name(s).

P the scaling magnification factorforthe specifiedaxes.

The axes programmed in the G14.1 block determine which axes are scaled.

The corresponding axis word values specify the center of scaling for each

axis. This position is the axis coordinate around which the scaling

operation is performed.

The scaling magnification factor (P) is the amount of scaling to be applied

to the programmed axes. Each axis can have a different scale factor by

programming them in separate G14.1 blocks. The scaling range is from

0.00001 to 999.99999. A scale factor less than one reduces a programmed

move while a scale factor greater than one enlarges a programmed move.

If no P word is programmed or if P0 is programmed in the G14.1 block,

the control uses the default magnification factor. If the programmed P

word value is out of range, an error message is displayed on the CRT.

When absolute mode (G90) is active, scaling moves are referenced from

the programmed center of scaling.
