Introduction to Programming
Chapter 10
10-22
This section describes general features of the words used in programming.
Later chapters in this manual describe, in detail, how to use these words.
To simplify programming an angle, corner radius, or chamfer between two
lines, all that is necessary is the angle between the lines and the radius or
chamfer size connecting them. This method of programming can be used
to simplify the cutting of many complex parts.
Quick path words are made up of the addresses below followed by the
desired numeric value.
,A ... angle
L ... length
,R ... corner radius
,C ... chamfer size
Important: A comma “,” must precede the, A ,R and ,C address characters
for the control to recognize them as radius or chamfer words.
For more details and examples using QuickPath Plus see chapter 15. For
more details and examples using radius and chamfer words see chapter 16.
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.
Specify a D address followed by a numeric value to call a value for the tool
diameter from the offset tables discussed in chapter 3. The diameter called
out from the table is used as the tool diameter when cutter compensation is
active (G41, and G42). For details on compensation see chapter 21.
Specify an H address followed by a numeric value to call a value for the tool
length offset from the offset tables discussed in chapter 3. The length called
out from the table is used as the tool length offset when programming Z
axes moves. For details on tool length offsets see chapter 20.
