6.6.2 Contours of the Lateral Surface
Cartesian or polar dimensions
The ”linear dimension CY” is given with respect to the unrolled
surface under ”reference diameter.”
Milling depth
For figures, enter the parameter ”Depth P.” If you use individual
elements for describing a milling contour, TURN PLUS opens the
”Pocket/contour” dialog box after you have finished your entries,
which requests ”Depth P.”
”Depth P” > 0 defines a pocket.
Starting point of lateral surface contour
To define the starting point, select Contour.
Parameters
Z:
Starting point of contour
P: Starting point of contour – polar
CY: Starting point of contour – angle as linear dimension
C: Starting point of contour – angle
Position of lateral-surface contours
TURN PLUS takes the selected reference plane and suggests it as
reference diameter.
”Reference data” dialog box
X:
Reference diameter
”Dimensions of lateral surface” soft key
Polar dimensions
Angle or angle as linear dimension
Polar dimension (parameter ”P”):
n ”P” is given with respect to the unrolled
lateral surface.
