10.3 Describing contours with mathematical
functions
Application
The Q parameters listed below enable you to program basic
mathematical functions in a machining program:
Select a Q parameter function: Press the Q key (in the numerical
keypad on the right). The Q parameter functions are displayed in
a soft key row
To select the basic mathematical functions, press the
BASIC ARITHM... soft key.
The control then displays the following soft keys:
Overview
Soft key Function
FN 0: ASSIGN
e. g., FN 0: Q5 = +60
Directly assign value
Reset Q parameter value
FN 1: ADDITION
e. g., FN 1: Q1 = -Q2 + -5
Calculate and assign the sum of two values
FN 2: SUBTRACTION
e. g. FN 2: Q1 = +10 - +5
Form and assign difference between two values
FN 3: MULTIPLICATION
e. g. FN 3: Q2 = +3 * +3
Form and assign the product of two values
FN 4: DIVISION e.g., FN 4: Q4 = +8 DIV +Q2
Calculate and assign the quotient of two values
Not permitted: Division by 0
FN 5: SQUARE ROOT e.g., FN 5: Q20 = SQRT 4
Calculate and assign the square root of a value
Not permitted: Square root of a negative value
You can enter the following to the right of the = sign:
Two numbers
Two Q parameters
A number and a Q parameter
The Q parameters and numerical values in the equations can be
entered with positive or negative signs.
