4.3 LINEAR INTERPOLATION (G01)
Tools can move along a line
Format
Explanation
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.
- 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
¿(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 and
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 1min.
G01 IP_ F_ ;
IP_ :For an absolute command, the coordinates of an end
point , and for an incremental commnad, the distance
the tool moves.
