4. INTERPOLATION FUNCTIONS
Tools can move along a line.
F_: Speed of tool feed (Feedrate)
_: For an absolute command, the coordinates of an end
point , and for an incremental command, the distance
the tool moves.
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.
For feed–per–minute mode under 2–axis simultaneous control, the
feedrate for a movement along each axis as follows :
Feed rate of α axis direction :
Feed rate of β axis direction :
