Three-dimensional movement
The NC block contains three coordinates. The TNC thus moves the
tool spatially to the programmed position.
Example
N50 G01 X+80 Y+0 Z-10*
Circles and circular arcs
The TNC moves two axes simultaneously on a circular path relative
to the workpiece. You can define a circular movement by entering
the circle center with
I
and
J
.
When you program a circle, the control assigns it to one of the
main planes. This main plane for a
T
must be defined when the
spindle axis is set:
Spindle axis
Main plane
(G17)
XY
, also UV, XV, UY
(G18)
ZX
, also WU, ZU, WX
(G19)
YZ
, also VW, YW, VZ
You can program circles that do not lie parallel to a
main plane by using the function for
Tilt working
plane
or with Q parameters.
the working plane (software option 8)", page 435
Direction of rotation DR for circular movements
When a circular path has no tangential transition to another contour
element, enter the direction of rotation as follows:
Clockwise direction of rotation:
G02/G12
Counterclockwise direction of rotation:
G03/G13
