6.2 Feedrate related functions
6.2.1 Feedrate programming units (G93/G94/G95)
The functions related to programming units permit selecting whether mm/minute
(inches/minute) or mm/revolution (inches/rev.) are programmed or, instead, the time the
axes will take to reach their target position.
Programming
The functions related to programming units are:
G94 Feedrate in millimeters/minute (inches/minute).
G95 Feedrate in millimeters/revolution (inches/revolution).
G93 Machining time in seconds.
These functions may be programmed anywhere in the program and they don't have to go
alone in the block. If the moving axis is rotary, the programming units will be in degrees
instead of millimeters or inches as follows:
G94
Feedrate in millimeters/minute (inches/minute).
After executing G94, the CNC interprets that the feedrates programmed with the "F" code
are in millimeters/minute (inches/minute). If the moving axis is rotary, the CNC interprets that
the programmed feedrate is in degrees/minute.
G95
Feedrate in millimeters/revolution (inches/revolution)
After executing G95, the CNC interprets that the feedrates programmed with the "F" code
are in mm/rev (inches/rev) of the master spindle of the channel. If the moving axis is rotary,
the CNC interprets that the programmed feedrate is in degrees/revolution.
If the spindle does not have an encoder, the CNC will use the programmed theoretical rpm
to calculate the feedrate. This function does not affect the movements in G00 which are
always executed in millimeters/minute (inches/minute).
G93
Machining time in seconds
After executing G93, the CNC interprets that the movements must be carried out in the time
period (seconds) indicated by the "F" code.
This function does not affect the movements in G00 which are always executed in
millimeters/minute (inches/minute).
Properties of the functions
Functions G93, G94 and G95 are modal and incompatible with each other.
On power-up, after an M02 or M30 and after an EMERGENCY or a RESET, the CNC
assumes function G94 or G95 as set by the machine manufacturer [G.M.P. "IFEED"].
