The first two command parameters are positioning parameters. Parameter word is the axis number (X, Y or Z)
of the two axes in current plane. The two positioning parameter specifies the location that the tool should be
moved in current plane. The third parameter word of the code parameter is the linear axis except circular
interpolation axis, which value is the height of the spiral. The specific meaning and limits of other code
parameters is the same in circular interpolation .
4.5 Feed per Minute / Feed Per Revolution (G94 / G95)
There are two ways to make the feed rate:
1.
Feed per minute(G94)
After F, specify the amount of feed of the tool per minute.
2.
Feed per revolution ( G95)
After F, specify the amount of feed of the tool per spindle revolution.
Format:
G94 F_; feed per minute, F: Feedrate command (mm / min or inch / min)
G95 F_; feed per revolution, F: Feedrate command (mm / rev or inch / rev)
Explanation:
1.
Tangential speed constant control
Cutting feed is controlled so that the tangential feedrate is always set at a specified feedrate.
2.
Feed per minute (G94)
After specifying G94 (in the feed per minute mode), the amount of feed of the tool per minute is to be
directly specified by setting a number after F. G94 is a modal code. Once a G94 is specified, it is valid until G95
(feed per revolution) is specified. At power–on, the feed per minute mode is set. An override from 0% to 150% (in
10% steps) can be applied to feed per minute with the switch on the machine operator’s panel.
3.
Feed per revolution (G95)
After specifying G95 (in the feed per revolution mode), the amount of feed of the tool per spindle revolution
is to be directly specified by setting a number after F. G95 is a modal code. Once a G95 is specified, it is valid
until G94 (feed per minute) is specified. An override from 0% to 150% (in 10% steps) can be applied to feed per
revolution with the switch on the machine operator’s panel.
Warning:
Some instructions can not be used for rate adjustments, such as tapping cycle.
4.6 Pause (G04)
Pause for a while between two programs. G04 makes the tool as no feed short finishing, generally used for
flat boring, countersink and other occasions.
Format:
G04X_; or G04P_; or G04U__;
Explanation:
G04P __; (unit: ms)
G04X __; (unit: seconds)
G04U __; (unit: seconds)
G04 specifies the pause, after a specified time delay, execute the next block. Delayed time is the specified
time by instruction, from 0.001~99999.999.Further, in order to check accurately by stopping in cutting mode (G64
mode), can specify a pause.
