Departure function DEP CT
Application
With the NC function DEP CT, the control departs from the contour on a circular path tangential to the last contour element.
Description of function
The tool moves on a circular path from the last contour point PE to the end point PN.
The circular path is defined by the center angle CCA and the radius R.
The direction of rotation of the circular path depends on the active radius compensation and the algebraic sign of the radius R.
The table shows the relationship between tool radius compensation and the algebraic sign of the radius R and the direction or rotation:
Radius compensation | Algebraic sign of radius | Direction of rotation |
---|---|---|
RL | Positive | Counterclockwise |
RL | Negative | Clockwise |
RR | Positive | Clockwise |
RR | Negative | Counterclockwise |
If you change the algebraic sign of the radius R, then the position of the auxiliary point PH changes.
The following applies regarding the center angle CCA:
- Only positive input values
- Maximum input value 360°
