Conditions
Î This function makes it possible to make
the execution of processing dependent on
a condition
- Transfer to the NC program
Î If a condition is met, processing is
executed; if it is not met, processing is not
executed
Î Condition fields can be switched on and
off using the Processing - Conditions
menu bars
The program system offers the following
options:
• Conditions with variables
L > 800 Î Variable L must be greater
than
800 mm
B < 600 Î Variable B must be less than
600 mm
Example:
Processing should only be executed with a
workpiece length (variable L) greater than
1000 mm. Î Condition: L > 1000

• Conditions dependent on processing
position
_mirror
Î Processing is only
executed in the mirrored
part
_nonmirro Î Processing is only
r
executed in the normal
part
Example:
• A “right-hand” and a “left-hand”
(= mirrored) part should be processed
Î Generation of the normal and the
mirrored NC program
• One of the processes, however, should be
executed in the “left-hand” (= mirrored)
part
Condition:
_mirror Î The macro is only written in
the mirrored NC program
Condition:
Macro active or inactive
1 Î Processing is always executed.
0 Î Processing is never executed.

4.7.3
It is possible to link conditions to one
another.
Î There are two operators available
AND link
The macro is active if all linked conditions
are met.
OR link
The macro is active if at least one of the
linked conditions is met.
Example:
Condition
_nonmirror AND L > 750
Condition is met for a normal part if the
variable L is greater than 750.
The condition is never met for the mirrored
part.
Note:
¾ Separate the AND and OR operators from
the conditions that are to be linked using
empty spaces
Î Variable names, functions, and conditions
must be used with the correct
capitalization rules

Other options
Hiding macros
¾ Press the space bar in the macro list
Ö The current macro will be displayed or
hidden
Î Hidden macros (green check-mark) are
not transferred to into the NC program
during NC generation
Î Is possible to write macro programs
containing the processes from various
workpiece versions and then to hide the
macros that are not needed depending on
the version.
IF...THEN...ELSE
This function can be used to make the value
of a parameter dependent on a condition.
Example of use:
A contour process is to be executed with a
cutter that cuts to the right and with a cutter
that cuts to left in the mirrored part.
Tool:
IF _nonmirror THEN 150 ELSE 151
15
Tool number, cutter that cuts to the
0
right
15
Tool number, cutter that cuts to the
1
left

woodWOP checks to see whether the
expression entered is computable.
• If so, then this expression is calculated
under the application of common
algebraic rules.
- Parenthetical priority, period before
dash, etc.
Î If the expression entered is faulty, then a
corresponding error message is
generated
The following elements are allowed:
• Numbers: e.g.. 34, 546.45, 0.455, .78, 004
• Variables from the list of variables
• Predefined constants and variables: e.g.
_mirror, _nonmirror
• Functions: e.g. SIN(45), COS(60),
TAN(22.5), SQRT(2)
• Operators: +, -, *, /, ^
• Comparisons: =, <, >, < =, > =, < >, (= <, =
>, > <, AND, OR)
Î The result of a comparison is 0.0
Ö The condition is not met
Î The result of a comparison is 1.0
Ö The condition is met
