Example
The following drawing must be supplemented by the value of the center circle point in order to be able to calculate the point
of intersection between the circle sectors of the straight lines.
Enter the coordinates of the pole, the slope angle of the straight line, the ordinate of the end point, and the circle radius as
the length.

Press this softkey to define the given end point when the abscissa value is given.
Press this softkey to define the second straight line which is rotated counter-clockwise by 90
degrees against the first straight line.
Press this softkey to define the second straight line which is rotated clockwise by 90 de-
grees against the first straight line.
4. Enter the PP coordinates, angle A, EP abscissa/ordinate, and L length in the respective
input fields. The following values of the straight line are known:
Straight line 1: Starting point and slope angle
Straight line 2: Length and one end point in the Cartesian coordinate system
5. Press this softkey to calculate the missing end point.
The abscissa value is displayed in the input field from which the calculator function has
been called, and the value of the ordinate is displayed in the next input field. If the function
is called from the part program editor, the coordinates are saved with the axis names of the
selected basic plane.
The missing center point coordinate is calculated using the calculator function, as the radius at the
tangential transition is perpendicular to the straight line.
The radius is located at an angle of 90° clockwise to the straight-line defined by the angle.
Use this softkey to select the appropriate direction of rotation.
Use this softkey to define the given end point.
