The graphic shows the simultaneous
movement of the A axis and the Y axis. In

they are interpolated linearly with one another.
A straight path of machine axes Y and A has
been programmed. Such a traversal command
G1 Y... A... produces the red, curved path for
A
the tool tip.
As a rule however, the behavior shown in
situation

regard to the tool tip is wanted for the G1
programming even when the A axis moves
simultaneously. In this case, the machine axis
movement follows the curved path. The Z axis
also moves to hold the tool tip in a straight
line.
