G233 2D/3D axis correction

With 2D/3D axis correction, an axis is corrected in dependency on one or two
axes via one of a maximum of 3 grid point tables.

G233 AXE

AXE

Identification of the axis, which should be corrected.
0: correction tables for the specified axis "off"
1: correction table 1 "on"
2: correction table 2 "on"
3: correction table 3 "on"

With this function, the position of an axis is corrected in dependency on one
to two basis axes via a previously loaded table with equidistant grid points.
In this case, the axis to be corrected may be one of the two basis axes. The
correction takes place with the offset specified in the table. The
interpolation between the grid points is linear.

The tool offset of the current tool Tn is calculated with G233 when the
function is switched on and therefore must not already be considered in the
loaded grid point table. The coordinates of the grid point table must be
related to the reference coordinate system including the basic offset, i.e. to
S0 without shift.

Up to 3 such correction tables can be loaded and be superimposed at the
same time. The same target axis can be involved several times. If several
correction tables are activated, the execution sequence of the corrections is
important:

Table 1: correction of Y depending on X

Table 2: correction of Z depending on X, Y

First 1 then 2: The correction of Y is included in the correction of Z and the
corrections are superimposed.

First 2 then 1: The corrections are independent and are not superimposed.

The sequence of the corrections to be executed corresponds to the
programming sequence of the G233 functions.

The correction tables are deactivated for all axes by programming G233
without axis letters and at the end of the program or in the event of a
program termination.

G233 Z2

Correction table 2 "on", target axis in the table must be Z

G233 Y1

Correction table 1 "on", target axis must be Y

G233 Y3

Correction table 3 "on", target axis must be Y

This defines the sequence: 2,1,3

G233 Z0

Correction of Z "off"

The remaining sequence is 1,3

G233 Y0

All correction tables of Y "off"
