Transitions between contour elements
A transition between two contour elements is called "tangential" when
one contour element makes a smooth and continuous transition to the
next. There is no visible kink or corner at the intersection. With
geometrically complex contours, tangential transitions are useful for
reducing the input of dimensional data to a minimum and eliminating
the possibility of mathematically contradictory entries.
To be able to calculate unsolved contour elements, MANUALplus
must know the type of transition that connects the contour elements.
The transition to the next contour element is determined by soft key.
Soft keys for tangential transitions
Tangential transition
from linear to circular element
Tangential transition
from circular element to circular or
linear element (for direction of
rotation, see symbol)
Error messages that occur during definition of the ICP
contour are often caused by "forgotten" tangential
transitions.
