Positioning Direction - HEIDENHAIN ITNC 530 - CYCLE PROGRAMMING User Manual

Positioning direction

The positioning direction of the rotary axis to be measured is
determined from the start angle and the end angle that you define in
the cycle. A reference measurement is automatically performed at 0°.
The TNC will issue an error message if the selected start angle, end
angle and number of measuring points result in a measuring position
of 0°.
Specify the start and end angles to ensure that the same position is
not measured twice. As mentioned above, a duplicated point
measurement (e.g. measuring positions +90° and -270°) is not
advisable, however it does not cause an error message.
Example: start angle = +90°, end angle = –90°
Start angle = +90°
End angle = –90°
No. of measuring points = 4
Stepping angle resulting from the calculation = (–90 - +90) / (4-1)
= –60°
Measuring point 1= +90°
Measuring point 2= +30°
Measuring point 3= -30°
Measuring point 4= –90°
Example: start angle = +90°, end angle = +270°
Start angle = +90°
End angle = +270°
No. of measuring points = 4
Stepping angle resulting from the calculation = (270 - 90) / (4-1)
= +60°
Measuring point 1= +90°
Measuring point 2= +150°
Measuring point 3= +210°
Measuring point 4= +270°
