Feed per revolution G95-Geo
G95 influences the finishing feed rate of G890 for basic contour
elements and form elements.
Additive compensation G149-Geo
G149 followed by a D number activates/deactivates an additive
compensation function. The Control manages the 16 tool-independent
compensation values in an internal table. The compensation values are
managed in the Program Run mode (see "Program Run mode" in the
User's Manual).
Example: Attributes in contour description G95

Parameter
F Feed per revolution
 The G95 finishing feed rate replaces a finishing feed rate
defined in the machining program.
 G95 is a modal function.
 To cancel a finishing feed rate set with G95, program
G95 without an input value.

Parameter
D Additive compensation (default: D900)
 D=900: Deactivates the additive compensation
 D=901 to 916: Activates the additive compensation D
 Note the direction of contour description.
 Additive compensation is effective from the block in
which G149 is programmed.
 Additive compensation remains in effect up to:
 the next G149 D900,
 up to the end of the finished part description.
