Programming dimensions

In this section you will find descriptions of the commands, with which you can directly
program dimensions taken from a drawing. This has the advantage that no extensive
calculations have to be made for NC programming.
Note
The commands described in this section stand in most cases at the start of a NC program.
The way, in which these functions are combined, is not intended to be a patent remedy. For
example, the choice of working plane may be made at another point in the NC program. The
real purpose of this and the following sections is to illustrate the conventional structure of an
NC program.

Value assignments Information
0.001 ... 359.999 Specified in degrees; the thread
starting point with G33 will be
offset by the specified value
n =1 or =2,
axis identifier: e.g. "SP1" or "C"
0.0000 ... 359.9999 specified in degrees; the
spindle stops at the specified
position (to achieve this, the
spindle must provide the
appropriate technical
prerequisites: position control)
Spindle number n: 1 or 2
Special function;
filling of the buffer memory until
STARTFIFO, "Buffer memory
full" or "End of program" is
detected.
Special function;
the buffer memory is filled at the
same time.
Special function; the next block
is only decoded if the block
before STOPRE is completed.
Can only be set with inclined
axis (TRAANG)
