6.2 Fundamentals of Path Functions
Entering more than three coordinates
The TNC can control up to 5 axes simultaneously (software option).
Machining with 5 axes, for example, moves 3 linear and 2 rotary axes
simultaneously.
Such programs are too complex to program at the machine, however,
and are usually created with a CAM system.
Example:
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 CC.
When you program a circle, the control assigns it to one of the main
planes. This plane is defined automatically when you set the spindle
axis during a TOOL CALL:
N123 G01 G40 X+20 Y+10 Z+2 A+15 C+6 F100 M3 *
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 tilting the working plane
(see User's Manual for Cycles, Cycle 19, WORKING
PLANE) or Q parameters (see "Principle and Overview",
page 254).
