SETTING A MULTI-CHANNEL SYSTEM.<br />
CNC <strong>8065</strong><br />
(REF: 1103)<br />
·38·<br />
Setting the machine parameters.<br />
The CNC displays the ·G· functions associated with the work planes.<br />
Configuration of "plane" type axes.<br />
Execution channels<br />
This configuration has two axes forming the usual work plane on a lathe. There may be more<br />
axes, but they cannot be part of the trihedron; there must be auxiliary, rotary, etc.<br />
With this configuration, the work plane is always G18 and will be formed by the first two axes<br />
defined in the channel. If the X (firs axis of the channel) and Z (second axis of the channel)<br />
have been defined, the work plane will be the ZX (Z as abscissa and X as ordinate).<br />
The work plane is always G18; machine parameter IPLANE is not applied and it is not<br />
possible to change planes via part-program. The ·G· functions associated with the work<br />
planes have the following effects.<br />
Function. Meaning.<br />
G17 It does not change planes and shows a warning about it.<br />
G18 It has no effect (except when function G20 is active).<br />
G19 It does not change planes and shows a warning about it.<br />
G20 It is permitted if it does not change the main plane; i.e. it can only be used to change<br />
the longitudinal axis.<br />
The CNC does not display the ·G· functions associated with the work planes because it is<br />
always the same plane.<br />
Configuration of "plane" type axes. Arc programming.<br />
Programming the arc center I K depends on the active work plane.<br />
With function G18, in circular interpolations, the arc center I is associated with the first<br />
axis of the channel (usually X) and K with the second axis of the channel (usually Z).<br />
With function G20, in circular interpolations, the arc center I is associated with the<br />
abscissa axis (usually Z) and K with the ordinate axis of the channel (usually X).<br />
Configuration of "plane" type axes. The longitudinal axis.<br />
In this configuration, the second axis of the channel is considered as longitudinal axis. If the<br />
X (first axis of the channel) and Z (second axis of the channel) axes have been defined, the<br />
work plane will be the ZX and Z will be the longitudinal axis. Tool length compensation is<br />
applied on this longitudinal axis when using milling tools. With lathe tools, tool length<br />
compensation is applied on all the axes where a tool offset has been defined.<br />
When using milling tools on a lathe, the longitudinal compensation axis may be changed by<br />
means of the #TOOLAX instruction or the G20 function.<br />
Configuration of "plane" type axes. Axis swapping.<br />
The axes may be swapped, but it must be borne in mind that the previous behavior stays<br />
the same for the first and second axes of the channel resulting from the swap.<br />
CONFIGURING THE SPINDLES OF THE CHANNEL.<br />
CHNSPDL<br />
Number of spindles of the channel.<br />
Possible values: From 0 to 4.<br />
Default value: 1.<br />
Associated variable: (V.)[ch].MPG.CHNSPDL<br />
This parameter sets the number of spindles of the channel, whether they are servo-controlled<br />
or not.<br />
A channel may have initially one, several or no spindles associated with it. In any case, the<br />
number of spindles assigned to the channel cannot be higher than the number of spindles<br />
of the system, defined by parameter NSPDL. The sum of the spindles assigned to the<br />
channels cannot exceed the number of spindles of the system either.
