3.12 ROTARY AXIS ORIGIN COMPENSATION AND ROTARY
AXIS OFFSET
Explanation
- Rotary axis origin compensation
When a rotary axis deviates slightly due to thermal displacement, the
deviation of the origin of the rotary axis can be set in parameter No.
7518 to perform origin compensation. The three-dimensional handle
feed is calculated with the angular displacement resulting from
compensating the angular displacement of the rotary axis with the
origin compensation set in the appropriate parameter.
- Rotary axis offset
The offset for the angular displacement of a rotary axis can be set in
parameter No. 7517 to perform compensation. The three-dimensional
handle feed is calculated with the angular displacement resulting from
compensating the angular displacement of the rotary axis with the
offset set in the appropriate parameter.
The angular displacement of a rotary axis that is used in the calculation
of the three-dimensional handle feed/interrupt when rotary axis origin
compensation and compensation with a rotary axis offset are performed
is as follows:
Angular displacement of the rotary axis = (angle of the rotary axis in
the machine coordinate system) - [parameter No. 7517 + parameter No.
7518]
