9.3 Describing contours with
mathematical functions
Application
The Q parameters listed below enable you to program basic
mathematical functions in a part program:
Select a Q-parameter function: Press the Q key (in the
numerical keypad at right). The Q-parameter functions are
displayed in a soft-key row
Select the mathematical functions: Press the
BASIC
ARITHMETIC soft key. The TNC then displays the following soft
keys:
Overview
Function Soft key
D00: ASSIGN
e.g.
D00 Q5 P01 +60 *
Directly assign value
D01: ADDITION
z.B.
D01 Q1 P01 -Q2 P02 -5 *
Form and assign sum from two values
D02: SUBTRACTION
e.g.
D02 Q1 P01 +10 P02 +5 *
Form and assign difference between two values
D03: MULTIPLICATION
e.g.
D03 Q2 P01 +3 P02 +3 *
Form and assign the product of two values
D04: DIVISION e.g. D04 Q4 P01 +8 P02 +Q2 *
Form and assign the quotient of two values Not
permitted: Division by 0
D05: SQUARE ROOT e.g. D05 Q50 P01 4 *
Form and assign the square root of a value Not
permitted: Square root from negative value
To the right of the "=" character you can enter the following:
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.
