Introduction to Programming
Chapter 10
10-21
This section describes general features of the words used in programming.
Later chapters in this manual describe in detail how to use these words.
Axis words are made up of an axis name followed by the desired numeric
value for that word.
For axis names, the system installer chooses from:
A B C U V W X Y Z $X $Y $Z $B $C
These are assigned in AMP. This manual assumes primary axes one, two,
and three to be labeled X, Y, and Z respectively. Integrand words for these
axes are assumed by be I, J, and K respectively.
Incremental or parallel
axis names for these axes are assumed to be U, V, W, respectively.
To simplify programming an angle, corner radius, or chamfer between two
lines, all you need is the angle between the lines and the radius or chamfer
size connecting them. You can use this method of programming to
simplify the grinding of many complex parts.
QuickPath words are made up of the addresses below followed by the
desired numeric value.
If you see: It means:
A angle
L length
,R corner radius
,C chamfer size
Important: A comma “,” must precede the R and C address characters for
the control to recognize them as radius (,R) and chamfer (,C) words.
For details and examples using these words, see chapter 12.
