Feedrate
The feedrate depends on the speed at which a manual handle is turned.
A distance to be traveled by the tool (along a tangent in the case of linear
or circular feed) when a manual handle is turned by one pulse can be
selected using the manual handle feed travel distance magnification
switch.
The FS16/18 has three manual pulse generator interfaces to allow up to
three manual handles to be connected. For information about how to use
the manual handles connected to the interfaces (whether to use each
manual handle as a handle for feed along an axis, as a guidance handle,
or as an approach handle), refer to the relevant manual provided by the
machine tool builder.
The user can specify the direction of the tool moved along a straight line
or circle (for example, whether to make a clockwise or counterclockwise
movement along a circle) when the guidance handle or approach handle
is turned clockwise or counterclockwise. For details, refer to the relevant
manual provided by the machine tool builder.
In jog feed, the tool can be moved along a specified axis (X–axis, Y–axis,
Z–axis, ..., or the 8th axis), or can be moved along a tilted straight line
(linear feed) or a circle (circular feed).
(1)Feed along a specified axis (simultaneous 1–axis control)
While a feed axis and its direction are specified with the feed axis
direction select switch, the tool moves in the specified axis direction
at the feedrate specified in parameter No. 1423. The feedrate can be
overridden using the manual feedrate override dial.
(2)Linear feed (simultaneous 2–axis control)
By defining a straight line beforehand, the tool can be moved as
follows:
D While a feed axis and its direction are selected using the feed axis
direction select switch, the tool moves along a straight line parallel
to the specified straight line on a simultaneous 2–axis control basis.
D While a feed axis and its direction are selected using the feed axis
direction select switch, the tool moves at right angles to the
specified straight line on a simultaneous 2–axis control basis.
The feedrate in the tangential direction is specified in parameter No.
1410. The feedrate can be overridden using the manual feedrate
override dial.
(3)Circular feed (simultaneous 2–axis control)
By defining a circle beforehand, the tool can be moved as follows:
D While a feed axis and its direction are selected using the feed axis
direction select switch, the tool moves from the current position
along the concentric circle that has the same center as the specified
circle.
D While a feed axis and its direction are selected using the feed axis
direction select switch, the tool moves along the normal to the
specified circle.
The feedrate in the tangential direction is specified in parameter No.
1410. The feedrate can be overridden using the manual feedrate
override dial.
