are enabled in addition to the conventional feed operation along a
specified single axis (X–axis, Y–axis, Z–axis, and so forth) based on
simultaneous 1–axis control:
D Feed along a tilted straight line in the XY plane (linear feed) based on
simultaneous 2–axis control
D Feed along a circle in the XY plane (circular feed) based on
simultaneous 2–axis control

Procedure for Manual Linear/Circular Interpolation
1 To perform manual handle feed, select manual handle feed mode. To
perform jog feed, select jog feed mode.
2 To perform manual handle feed, select a feed axis (for simultaneous
1–axis feed along the X–axis, Y–axis, or Z–axis, or for simultaneous
linear or circular 2–axis feed along a specified straight line or circle in
the XY plane) subject to manual handle feed operation. Use the
handle feed axis select switch for this selection.
To perform jog feed, select a feed axis and direction with the feed axis
direction select switch. While a feed axis and its direction are
specified, the tool moves in the specified axis direction or along a
straight line or circle at the jog feedrate specified in parameter No.

3 For manual handle feed
The tool is moved along a specified axis by turning the respective
manual handle. The feedrate depends on the speed at which the
manual handle is turned. A distance to be traveled by the tool when
the manual handle is turned by one pulse can be selected using the
manual handle feed travel distance magnification switch.
