Tools can move along a line
F_:Speed of tool feed (Feedrate)
IP_:For an absolute command, the coordinates of an end point ,
and for an incremental commnad, the distance the tool moves.
G01 IP_F_;
A tools move along a line to the specified position at the feedrate
specified in F.
The feedrate specified in F is effective until a new value is specified. It
need not be specified for each block.
The feedrate commanded by the F code is measured along the tool path.
If the F code is not commanded, the feedrate is regarded as zero.
The feedrate of each axis direction is as follows.

Feed rate of Ζ axis direction :
The feed rate of the rotary axis is commanded in the unit of deg/min (the
unit is decimal point position).
When the straight line axis α(such as X, Y, or Z) and the rotating axisβ
(such as A, B, or C) are linearly interpolated, the feed rate is that in which
the tangential feed rate in the αandβ cartesian coordinate system is
commanded by F(mm/min).
β–axis feedrate is obtained ; at first, the time required for distribution is
calculated by using the above fromula, then the β –axis feedrate unit is
changed to deg 1min.
