Machining time or feedrate (G93/G94/G95/G194)

Syntax:

G93

Specify machining time in seconds

modal

G94

Feed per minute

modal, initial state

G95

Feedrate per revolution

modal

G194

Feedrate calculation based on maximum weighted axis feeds

modal

The action of the F word can be optionally switched over by using the G functions G93, G94, G95 and G194.

G93 combined with the F word defines a machining time in [s].

G94 combined with the F word:

G95 combined with the F word defines a feedrate per revolution in [mm/U, inch/U]. The function is described in greater detail in Section Feedrate per revolution (G95).

G194 combined with the F word defines a weighting factor in [%] for maximum feedrates. The maximum permissible feedrate on the path then results from the axis-specific values P-AXIS-00212. At least one axis then moves at its maximum weighted velocity. Only weighting factors less than 100% are permitted.

Programing Example

Machining time or feedrate (G93/G94/G95/G194)

N10 G90 F1000 X100   (Feedrate 1000 mm/min (G94 default))

N20 G194 F90         (Weighting 90% to max. axis feedrate)

Nxx X200             (Feedrate e.g. 9000 mm/min at vb_max=10000 mm/min)

N80 G94 X50          (Feedrate 1000 mm/min valid from N10)

N120 G93 F20         (Machining time 20 s)
