6.2 LINEAR INTERPOLATION
General
Tools can move along a line
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 (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 -
axis feedrate unit is changed to deg/min.
