Program code Comment
N130 G95 G1 FZ0.03 X20 ; Path motion, the effective feedrate is dependent upon:
- The tooth feedrate FZ
- The speed of spindle 2
- The number of teeth of the active tool T1
Note
Following the change in the master spindle (N100), a tool actuated by spindle 2 must be
substituted (N110).
Further information
Changing between G93, G94 and G95
FZ can also be programmed when G95 is not active, although it will have no effect and is
deleted when G95 is selected. In other words, when changing between G93, G94, and G95, in
the same way as with F, the FZ value is also deleted.
Reselection of G95
Reselecting G95 when G95 is already active has no effect (unless a change between F and FZ
has been programmed).
Non-modal feedrate (FB)
When G95 FZ... (modal) is active, a non-modal feedrate FB... is interpreted as a tooth
feedrate.
SAVE mechanism
In subprograms with the SAVE attribute FZ is written to the value prior to the subprogram
starting (in the same way as F).
Multiple feedrate values in one block
The "Multiple feedrate values in one block" function is not possible with tooth feedrate.
Synchronized actions
FZ cannot be programmed from synchronized actions.
Read tooth feedrate and path feedrate type
The tooth feedrate and the path feedrate type can be read using system variables.
