4.2
Linear Interpolation (GOI)
GOlP
F
;
This comman~ate~linear interpolation mode. The values of P define the
distance of tool travel which will be conducted in absolute or incremental mode,
according to the current status of G90IG91.
For example, when this command is
specified in the absolute mode, the tool moves to a certain point in the selected work
coordinate system along a straight line at the feedrate specified by the F code. Men
commanded in the incremental mode, the tool moves from the current position to the
point separated by a certain value along a straight line at the feedrate specified by the
F code. Since the feedrate specified by the F code remains effective until a new
feedrate is commanded, it need not be specified again.

The speed specified by F is that the tool move along a line. If it is not commanded,
the feed rate is regarded as zero.
(Note 1)
Feedrate along each axis is as follows :
