1.2 Application of Q parameters
1, the same type of parts |
| Use Q parameters instead of critical dimensions, or process parameters, to achieve program generalization |
2, free contour curve |
| Automatically calculate coordinate points on the formula curve |
3, 3D contour |
| Various 3D contour machining |
1.3Q parameter command
Press the iTNC530 system keyboard 
After the key, there are 8 sets of soft keys at the bottom of the screen:
Their functions are:
Basic numerical operation | BASIC ARITHM. | Negative value, addition, subtraction, multiplication, division, etc. |
Trigonometric function | TRIGO-NOMETRY | SIN COS TAN, etc. |
3 or 4 point calculation arc | CIRCLE CALCU-LATION | Calculate the center of the circle diameter at coordinates of 3 or 4 points on the arc |
Conditional jump instruction | JUMP | Conditional judgment jump, such as greater than jump, etc. |
special function | DIVERSE FUNCTION | PLC, NC data exchange, printing and other functions |
formula | FORMULA | Complex mathematical calculation formula |
Contour calculation | CONTOUR FORMULA | Calculating open contours in SL loops |
String calculation | STRING FORMULA | Character processing |
