Absolute or incremental dimensions
The setting of the
Increment
soft key determines which type of
coordinate is active. Incremental parameters will have the appendix
i ( Xi , Zi , etc.).

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 unresolved contour elements, the control
must know the type of transition that connects the contour
elements. The transition to the next contour element is determined
by soft key.
Error messages that occur during definition of the
ICP contour are often caused by forgotten tangential
transitions.
Soft key for tangential transition
Activates the tangential condition for the
transition in the end point of the contour
element
