With the NC function APPR PLCT, the control approaches the contour in a straight line, followed by a circular path tangential to the first contour element.
Coordinates of the first contour point are programmed with polar coordinates.
With the NC function APPR PLCT, the control approaches the contour in a straight line, followed by a circular path tangential to the first contour element.
Coordinates of the first contour point are programmed with polar coordinates.
You must define a pole CC before programming with polar coordinates.
The straight line is tangential to the circular path.
The auxiliary point PH is determined based on the starting point PS, the radius R and the first contour point PA.
The circular path is uniquely defined by the radius R.
If you program the Z coordinates in the approach function, then the tool approaches simultaneously in three axes from the starting point PS to the auxiliary point PH.
NC programs contained in this User's Manual are suggestions for solutions. The NC programs or individual NC blocks must be adapted before being used on a machine.
Some NC programs depend on the machine kinematics. Adapt these NC programs to your machine kinematics before the first test run.
In addition, test the NC programs using the simulation before the actual program run.
With a program test you determine whether the NC program can be used with the available software options, the active machine kinematics and the current machine configuration.
