4 The Interpolation

Feed along the axis Y is

.............................

Feed along the axis U is

.............................

Feed along the axis C is

where x, y, u, c are the displacements programmed along the respective axes, L is the vectorial length of programmed displacement:

G01 X100 Y80 F150

Fig. 4.2-1

The feed along a rotational axis is interpreted in units of degrees per minute (°/min):

G01 B270 F120

In the above block, F120 means 120deg/minute.

If the motion of a linear and a rotary axis is combined through linear interpolation, the feed components will be distributed according to the above formula. E.g. in block

G91 G01 Z100 B45 F120

Fig. 4.2-2

feed components in Z and B directions are:

feed along axis Z:

mm/min

feed along axis B:

°/min

Being a modal code, G01 is effective until rewritten by another interpolation command. After power-on, G00 or G01 is effective, depending on the parameter value set in group CODES of the parameter field.
