Coordinate Control
Chapter 11
11-8
There are 3 methods to change the value of a work coordinate system zero
point in the work coordinate system table. You can find two methods in
these chapters:
Method: Chapter:
Manually alter the work coordinate system table 3
Alter the paramacro system parameter values 5221 - 5386 20
The third method, the one described in this chapter, alters the work
coordinate system table through G10 programming. Changing the values
in the table by using any of these methods does not cause axis motion;
however, it does immediately shift the active coordinate system by the
amount entered. The format for altering the work coordinate systems
using G10 is as follows:
G10 L2 P__ O__ X__ Z__;
Where : Tell(s) the control:
L2 that you want to alter the coordinate system tables.
P__ which coordinate system (G54 through G59.3) you want to work on. P1 through
P9 correspond to the work coordinate systems G54 through G59.3.
P1 = G54 work coord. system P6 = G59 work coord. system
P2 = G55 work coord. system P7 = G59.1 work coord. system
P3 = G56 work coord. system P8 = G59.2 work coord. system
P4 = G57 work coord. system P9 = G59.3 work coord. system
P5 = G58 work coord. system
O__ whether the value entered for the diameter axis is a radius or diameter value. (O
is non-modal, and it applies to cylindrical grinders only)
O1=value entered for the diameter axis is a radius value.
O2=value entered for the diameter axis is a diameter value.
Important: If you program O1 or O2 in a G10 code, the G10 code is not
affected by a previously programmed G07 or G08 (radius/diameter
programming). However, if no O code is specified, or if the O code is out of
range (for example, O3), then the G10 code is affected by a G07/G08.
X_Z_ the location of the zero point of the specified work coordinate system relative to
machine coordinate system.
Important: You cannot program G10 blocks when dresser/wheel radius
compensation is active.
