3.4 Linear Interpolation (G01)
A tools move along a line to the specified position at the feedrate specified in F.
Format: G01 X/U_ Z/W_ Y(C)/V_ A_ F_ ;
X,Z,Y(C), A means motion axis.For an absolute command, the coordinates of an end point ,
and for an incremental command, the distance the tool moves.
F: Speed of tool feed(Feedrate)
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.
For feed–per–minute mode under 2–axis simultaneous control, the feedrate for a movement
along each axis as follows :
The feedrate of the rotary axis is command 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 axis β (such as A, B, or C)
are linearly interpolated, the feed rate is that in which the tangential feed rate in the α & β
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 formula, then the β-axis feedrate unit is changed to deg/min.
A calculation example is as follow.
G91 G01 X20.0 A40.0 F300.0
This changes the unit of the A axis from 40.0 deg to 40mm with metric input. The time
required for distribution is calculated as follow:
