Commands Calling Axis Movements

2.1 Interpolation commands

This section describes the positioning commands and the interpolation commands

that control the tool path along the s pecified functions such as straight line and arc.

2.1.1 Positioning (G00)

In the absolute programming mode (G90), the axes are moved to the s pecified

point in a workpiece coordinate system, and in the incremental programming mode

(G91), the axes move by the specified distance from the present position at a rapid

traverse rate.

For calling the positioning, the following G codes can be used.

Positioning (G00)

Format

G00 X... Y... Z... ;

Explanation

When G00 is designated, positioning is executed. The program advances to the

next block only when the number of lag pulses due to servo lag are checked after

the completion of pulse distribution has reduced to the permissible value.

In the G00 mode, positioning is made at a rapid traverse rate in the simultaneous

3-axis (*5-axis) control mode. The axes not designated in the G00 block do not mo-

ve. In positioning operation, the individual axes move independently of each other

at a rapid traverse rate that is set for each axis. The rapid traverse rates set for the

individual axes differ depending on the machine. For the rapid traverse rates of

your machine, refer to the manuals published by the machine tool builder.
